Due to the Loads and Loads of Characters spread out among multiple factions among the game's various routes, this character page is split into multiple sections.
- Main Protagonists note
- The Black Eagles note
- The Blue Lions note
- The Golden Deer note
- The Church of Seiros note
The Three Houses in GeneralThe houses of the Officers Academy are each made up of students from one of three nations in Fódlan. They are the titular protagonist groups of the game. As teacher, the player gets to choose one of them to lead and instruct.
- Animal Motifs: Each house is represented by an animal: Eagle, Lion, and Deer.
- Color-Coded for Your Convenience: Each of the factions, as with the nations they represent, is associated with a color:
- Black Eagles/Adrestian Empire: Red
- Blue Lions/Holy Kingdom of Faerghus: Blue
- Golden Deer/Leicester Alliance: Yellow
- Church of Seiros: Silver on their flag, Purple on the world map, but the leadership is associated with Green.
- "Those who slither in the dark"/Nemesis: Black
- Team Title: Because of the game being known outside of Japan as Three Houses and its setting, the houses are the focus of the story and gameplay.
The Three Nations of Fódlan - Adrestian Empire
The Adrestian Empire
The oldest and largest nation in all of Fódlan, encompassing the southern part of the continent. Founded 1000 years ago by Seiros & the Ten Elites after the War of Heroes, the Adrestian Empire has been ruled by the same dynasty for its entire existence. Over time, various territories seceded from the Empire, forming both the Holy Kingdom of Faerghus and the Leicester Alliance. Despite its power having waned over the millennium, the Empire remains one of the most powerful forces on the continent. Adrestian students at the Officers Academy are members of the Black Eagles.
- The Empire: Once had dominion over the entirety of Fódlan, and still controls the southern half & at least one vassal state.
- Faction Calculus: Powerhouse. The empire primarily relies on hard-hitting magic-users and armour knights to overwhelm the enemy.
- Fantasy Counterpart Culture:
- Germany, particularly the Holy Roman Empire. Evident with the names of the students & the twin-headed eagle banner of the empire.
- To the Austrian Empire. The black eagle and the color red of their associated house both call to mind the House of Habsburg, which ruled over the Empire. Unlike the Holy Roman Empire which was more a confederacy of states, the Adrestian Empire is an authoritarian Empire. Their political situation even sort of mirrors the later Austrian Empire at the dawn of WW1, having had many parts of it break off and becoming independent but the Empire being militaristic and inclined towards reconquering lost lands.
- Fighter, Mage, Thief: Mage. Adrestia relies heavily on its mages in its military.
- Hegemonic Empire: After the resurgence of the Unified Empire in Crimson Flower's ending, the Empire became this under Edelgard's rule.
- The Purge: Upon taking power, Edelgard and Hubert conduct one on the corrupt nobility and those who oppose them. The lucky ones, such as Count Varley, are simply stripped of their titles and placed under house arrest. The unlucky ones, such as Hubert's father, are killed outright.
- Resurgent Empire: On the Crimson Flower route, the empire successfully unifies Fódlan once again by conquering Faerghus and the Leicester Alliance, restoring it to its original size.
- Vestigial Empire: Downplayed. While Adrestia is nowhere near the peak of its power like it once was, it's still the most powerful force on the continent. And should Byleth side with Edelgard and the Black Eagles, "vestigial" goes right out the window.
The Brigid Archipelago
An archipelago off Fódlan's west coast. They serve the Adrestian Empire as a vassal state.
- Born Under the Sail: Petra mentions they have a rather strong sailing tradition, fitting for an archipelago nation.
- Fantasy Counterpart Culture: Ireland, though it has some aspects of various Native American cultures and a strong sailing tradition.
- Voluntary Vassal: They act as a vassal state to Adrestia. Interactions with Petra show that the vassalage is less than voluntary, and Petra is in Fódlan as a prisoner/bargaining chip. In the non-Crimson Flower routes, they are rather quick to throw their support behind whichever faction Petra joins. Provided Petra survives, they regain their independence in the aftermath of every route, but maintain their alliance with the newly unified Fódlan.
- Alas, Poor Villain: The former duke is killed by Hrym people who blamed him for their current hardships, since he was the ruler who initially taxed them harshly. Though Lysithea, who's from House Ordelia and knows the history of Hrym and Ordelia, has reason to hate him, she remarks that it really wasn't his fault this time, as he hasn't been in charge of Hrym for several years, and feels his murder wasn't deserved.
- Asshole Victim: While he was killed because of something that wasn't his fault this time, the fact that he's a corrupt Evil Chancellor who masterminded the Crest experimentation that gave Edelgard her second Crest and killed or crippled the rest of her siblings can make it hard to feel sorry for him.
- Bald of Evil: He's noticeably losing hair, and he's corrupt.
- The Dog Bites Back: After the insurrection, Duke Aegir was put in charge of Hrym, and he levied brutally heavy taxes and fines on the people, more than that of his own territory. Once he was stripped of his power, Arundel took his place. A group of rogues from Hrym found Aegir traveling alone in the forest. Blaming him for their misery, they killed him and stole his belongings.
- Evil Chancellor: He led a conspiracy of nobles to seize power for themselves, leaving the emperor their puppet. According to Edelgard, he also masterminded the Crest experimentation that gave Edelgard her second Crest and killed or crippled the rest of her siblings.
- Fat Bastard: He has a noticeable gut, and he's counted amongst the corrupt nobility.
- Killed Offscreen: He dies during the timeskip if Ferdinand isnt in your party.
- Know When to Fold 'Em: When Edelgard is made Emperor and makes one of her first decrees to strip him of his titles, Duke Aegir tries to argue before backing down, realizing that he's not dealing with a feeble old man anymore but someone with every reason and ability to have him killed.
- Like Father, Unlike Son: Duke Aegir is pretty much the exact kind of noble Ferdinand despises, and is likely the reason why Ferdinand tries to act as a proper noble. In fact, though Ferdinand is not happy about Edelgard deposing his father, he will still readily admit that the man was indeed greedy and arrogant.
- Misplaced Retribution: Played with. He did in fact harshly tax the citizens of Hrym, far more so than those of his home territory, to the point of causing droves of people to attempt to flee to Ordelia in desperation. After he lost his noble title, he's imprisoned in Enbarr for years while Lord Arundel took charge of Hrym. Arundel imposed even heavier taxes on the people, and they're conscripted for war as well — this Arundel did in the name of Aegir, stoking the people's fury and directing it at Aegir. When the former duke finally escapes imprisonment, rioters at Hrym kill him. As Lysithea explains, he was by no means a great ruler, but he was not the villain this time.
- No Name Given: He's only referred to as "Duke Aegir" or "Prime Minister" with no first name given aloud.
- Unwitting Pawn: Ultimately, the main beneficiary of his conspiracy was Lord Arundel/Thales, who used the opportunity to amass power and conduct experiments on the imperial family. Indeed, Arundel openly turns against him the moment Edelgard takes the throne.
Lord Volkhard von Arundel
Class: Dark Knight
Voiced by: Masaki Terasoma (Japanese), Christopher Corey Smith (credited as Chris Smith) (English)
- Evil Uncle: He's Edelgard's uncle and Dimitri's step-uncle, who experiments on and kills the siblings of the former and tries to kill the latter. Naturally, as he's really a disguised Thales.
- Face Death with Dignity: On the Azure Moon route, where he finds the light he longed for in death.
- Faux Affably Evil: In Hubert's Paralogue, Arundel remains polite throughout and asks for "help" in dealing with some Black Beasts that went out of "those who slither in the dark's" control, and even allows Hubert and Byleth to take the "Arrow of Indra" as a gift for their work in saving the mages caught up in the chaos. Hubert, however, makes it abundantly clear Arundel was using the incident as a means of demonstrating "those who slither in the dark's" power with even the "gift" being a prototype magical lance nearly as powerful as a Hero's Relic yet capable of being wielded by anyone.
- Karmic Death: On the Azure Moon route he is killed by Dimitri's army, the man who lost his family in the Tragedy of Duscur which Arundel helped orchestrate. The kicker being is Dimitri never found out who was responsible for it. So he avenged his family without even knowing it.
- Kill and Replace: While it is ultimately left ambiguous, it is noted on the Azure Moon route that Arundel was a very generous donor to the Church of Seiros up until a few years before the game started, and so it is heavily implied that the real Lord Arundel was replaced by Thales at that point.
- Manipulative Bastard: Instigated the Tragedy of Duscur via his underling Cornelia and Edelgard's mother.
- Sugary Malice: On the Crimson Flower route, after the battle at Arianrhod, he politely talks to Edelgard the way one would expect a lord to speak to his empress, but the underlining sentiment behind his words makes it clear he sees the death of his underling Cornelia as a betrayal and that he will exact penance. True to his word, Hubert almost immediately comes running after this declaration to reveal Arianrhod has been destroyed entirely by "those who slither in the dark"'s javelins of light.
- The Unfought: Arundel is never faced on the Crimson Flower, Verdant Wind, or the Silver Snow route. Subverted for his real identity, Thales, who you actually get to fight on the Verdant Wind and Silver Snow.
- The Usurper: According to Hubert, it was Lord Arundel who spirited Edelgard off to Faerghus as a child and later, with the aid of Prime Minister Aegir and Hubert's father rendered Ionius politically impotent.
- Weapon for Intimidation: On the Crimson Flower route he has the fortress city of Arianrhod destroyed and a good portion of the Imperial army stationed there slain by the "javelins of light" to try and put Edelgard in her place for killing Cornelia. This only motivates Edelgard, Hubert and Byleth even further to give him and his group what's coming to them.
- Wolf in Sheep's Clothing: His real identity is Thales, the leader of "those who slither in the dark," himself.
- You Remind Me of X: Hubert in his B-Support with Byleth mentions that he senses something similar about them to Arundel, specifically that they have a "second self" they are in constant dialogue with. This doesn't bode well since Hubert hates Arundel.
Fleche von Bergliez
Voiced by: Yui Nakajima (Japanese), Eden Riegel (English)
- Alas, Poor Villain: On the Azure Moon route, after Byleth mortally wounds her to prevent her from killing Dimitri, she dies crying for her already dead brother, begging him to save her.
- Anti-Villain: Just like her brother Randolph, she's technically considered a villain outside of the Crimson Flower route because she is with the Adrestian Empire, opposing the Faerghus Kingdom/Leicester Alliance/Church of Seiros. On the Azure Moon route, she tries to kill Dimitri and Rodrigue dies taking the blow, but she does it to avenge the death of her brother.
- Avenging the Villain: While Randolph isn't really evil, she hates and tries to murder Dimitri in response to his death, even though Randolph was an enemy general trying to invade Dimitri's base in an offensive war.
- Big Brother Worship: She's shown to have quite the high opinion of Randolph. Her attempt at avenging him on the Azure Moon path most certainly came from a place of love.
- Broken Bird:
- She's ordinarily a Nice Girl; however, on the Azure Moon path she can't stand how Randolph met his end and plots to kill Dimitri once he drops his guard.
- Averted in the other routes where she handles her brother's death better. She's sad, but she doesn't wish to seek revenge, likely because he dies on the battlefield instead of her believing he was tortured to death.
- Death by Irony: On the Azure Moon route, she tries to kill whom she thinks murdered her beloved brother, but she gets struck down by the person who was actually responsible.
- Irony: It's strongly implied on Azure Moon that she acts as she does based on the belief her brother was tortured before Dimitri killed him. Not only does Dimitri never get the chance, Byleth does the deed to spare him. Fleche ends up being Not So Different to Dimitri in misplacing their target of revenge due to lacking key details.
- Nightmare Face: She sports an absolutely deranged scowl as she attacks Dimitri and rants at him for murdering her brother.
- Revenge: Attempts to avenge Randolph on the Azure Moon route, stabbing Dimitri before being struck down. Rodrigue's death and last words from her assassination attempt causes him to realize the pain he's caused and start the path of atonement.
- You Monster!: On the Azure Moon route, she snarls that Dimitri is a monster after swearing that she'll never forgive him for Randolph's death, right before she attempts to stab him in the back.
Emperor Ionius IX
Voiced by: Kouichi Souma (Japanese), Paul St. Peter (English)
- Abdicate the Throne: Just before the Time Skip, he abdicates his throne in favor of Edelgard, believing that she will be a more capable monarch than he was.
- Adult Fear: He confesses this regarding the experimentation done on Edelgard and her siblings. The Insurrection of the Seven, which reduced him to a mere figurehead, left him powerless to help his children, and he was horrified by what happened to them.
- The Casanova: Downplayed. According to Edelgard, out of necessity and need for heirs, he had a bevy of lovers despite being married. He fathered a total of eleven children during his reign, though only Edelgard survived.
- Creepy Shadowed Undereyes: They highlight his age and illness.
- First Love: Also doubles as Love at First Sight. Meeting Edelgard at the Goddess Tower will reveal that her mother, Patricia, was this for him. Ionius was a student of the Officers Academy before becoming Emperor and when he was crowned after graduation, he married for political reasons. One day, he visited the monastery and snuck up the Goddess Tower out of nostalgia. There, he met Patricia, who had just enrolled, and the pair fell in love immediately. But:immediately afterward, Edelgard admits that's how the "story" goes, implying it could just be Imperial propaganda and that she wants to believe her parents were in love with each other, even if it isn't the truth.
- Good Parents: There are plenty of signs that he truly loves Edelgard, and he expresses regret at how he could do nothing to help her when she was experimented on with the rest of her siblings and how she was taken to the Holy Kingdom of Faerghus. The fact that Edelgard doesn't hold him in contempt further cements this.
- Incurable Cough of Death: His speech is peppered with coughs, showing just how weak he's become.
- Killed Offscreen: After abdicating and passing on his throne to Edelgard, he is not seen again. Given that he was already half-dead from illness at that time, it should come as no surprise when Edelgard mentions near the end of the story that he died quite a while ago, as she reflects on all the tragic events that have shaped her life.Edelgard: Everything that's happened... it's all just part of the ebb and flow of history. The Tragedy of Duscur, our days at the academy, Father's death, and the five years you were gone... After all of that, at long last, we're here at this point in time. I hope you'll stay by my side until the very end.
- King on His Deathbed: Given his constant coughing and the weariness in his voice, it is evident that he is not long for this world.
- Puppet King: What he's been reduced to as a result of his age, illness, and the machinations of the corrupt nobility, all of which have left him too weak to effectively fight policies he doesn't agree with. However, it is still he alone who has the ability to crown his successor as Emperor, which he grants Edelgard when she comes to him for it.
- Small Role, Big Impact: The man appears in only one scene on the Crimson Flower route, and an optional one at that. In spite of this, the events of this scene canonically happen in all routes, and it forever alters the entire course of the continent.
- Strong Empire, Shriveled Emperor: Adestria may be a Vestigial Empire in the current day, but it's still the most powerful nation in Fódlan. Ionius himself, by contrast, is an old man wracked with illness and reduced to a Puppet King by several traitorous nobles, and he hates it for what his weakness cost his children and sole surviving heir Edelgard.
Class: Cavalier → Wyvern Rider → Wyvern Lord
Voiced by: Noriko Namiki (Japanese), Katelyn Gault (English)
- A Hero to His Hometown: She's rather popular amongst the citizens of the empire, who see her as a war hero.
- Anti-Villain: Even outside of the Crimson Flower route, Ladislava is not what you would call evil, as she's an honorable woman well loved among the Empire's citizens as a hero, only being considered a villain because her faction opposes the Faerghus Kingdom/Leicester Alliance/Church of Seiros.
- Dragon Rider: She's a powerful Wyvern Rider, although oddly she's a Cavalier in her Guest-Star Party Member appearance on the Crimson Flower route during the battle of Garreg Mach.
- Killed Offscreen: According to Randolph, she meets her end during the Church's attempt to recapture Garreg Mach on the Crimson Flower route.
- Humble Hero: Despite her abilities, she doesn't boast about them, which makes her rather relatable to citizens.
- Mauve Shirt: On the Crimson Flower route, she's basically a high-ranking mook with her own face and personality.
- Rank Up: Post-timeskip on the Crimson Flower route, she's gone from head of Edelgard's personal guard to a general in the army. Of course, this means she's no longer capable of protecting Edelgard herself and thus she entrusts that role to Byleth.
- Red Baron: She's called the "Scarlet Warrior."
- Supporting Leader: On the Crimson Flower route, she takes care of important logistical concerns in running the Adrestian army that Byleth can't (such as maintaining order in recently occupied territories).
Randolph von Bergliez
Voiced by: Jun Konno (Japanese), Ben Pronsky (English)
- Anti-Villain: Even outside of the Crimson Flower route, Randolph is not what you would call evil, only being considered a villain because he is with the Adrestian Empire, opposing the Faerghus Kingdom/Leicester Alliance/Church of Seiros. This is somewhat Deconstructed on the Azure Moon route, as Dimitri points out that he's still killed countless people in battle.
- Big Brother Instinct: He keeps Fleche from joining him in battle, especially on the Azure Moon route, where he fears the "One-eyed man" (Dimitri), who is infamous for brutally killing soldiers.
- Break the Haughty: At the receiving end of a Breaking Speech in a combination of Armor-Piercing Question, Not So Different, and These Hands Have Killed by Dimitri to which he tries to deny, but Dimitri refutes his responses because they're in a war while shooting down his excuses.
- Deconstructed Character Archetype: On the Azure Moon route only, of the Noble Top Enforcer antagonists often seen in Fire Emblem. While he fights for sympathetic reasons, his honour-bound tendencies end up being his downfall, and Dimitri makes a solid point that trying to claim the moral high ground in war doesn't make one any less of a killer.Randolph: This... this is war. I did what I had to; for the Empire... for my people... for my family.
Dimitri: So, you are piling up corpses for the people and your family. And I'm doing the same for the salvation of the dead. After all is said and done, we are both murderers, both stained... both monsters.
- Fatal Flaw: His Hot-Blooded nature and glory seeking tendencies prove to be this, as in every route except the Crimson Flower route, during the defense of Garreg Mach from Imperial forces, one of Byleth's allies (Claude on the Verdant Wind route, Gilbert on the Azure Moon route, and Seteth on the Silver Snow route) taunts him, intending to trick him into marching his soldiers headfirst into a fire trap. In every route where this crops up, Randolph is so incensed by the taunting that he sends his men forward, right into said trap.
- Glory Seeker: Seeks glory for the sake of his family and little sister.
- Heroic Sacrifice: On the Crimson Flower route, he dies of his wounds from defending Garreg Mach from the Churchs surprise attack.
- Hot-Blooded: He's not too far off from his nephew Caspar in this department. Fleche is constantly worried about him because of it.
- Mauve Shirt: On the Crimson Flower route, he's basically a high-ranking mook with his own face and personality.
- Mercy Kill: On the Azure Moon route, after he is defeated and captured by the Blue Lions, Dimitri contemplates how he is going to torture him, either by forcing Randolph to watch his comrades be killed one by one before him or by simply gouging his eyes out. To spare him, Byleth steps in and quickly executes Randolph before Dimitri is able to do either of these things.
- Parental Favoritism: His father, the previous Count Bergliez and Caspar's grandfather, favored his second wife, Randolph's mother, and she hoped that Randolph would succeed him to the countdom, despite the previous count having an older son from his first marriage, Caspar's father and Randolph's half-brother. Ultimately, Caspar's father inherited the countdom after the previous count was forced to retire early on account of poor health.
- Supporting Leader: On the Crimson Flower route, he takes care of important logistical concerns in running the Adrestian army that Byleth can't (such as keeping the monastery secure when Byleth and co. are on the front lines).
The Minister of Religious Affairs and Bernadetta's father.
- Abusive Parents: He treated his daughter terribly, such as tying her to a chair in order to mold her into an obedient wife, and prohibiting her from befriending commoners. Some of Bernadetta's behavior implies he may have been physically abusive.
- The Ghost: He never appears onscreen. However, he is allegedly behind the reinforcements Enbarr recieves during the final stage of the Azure Moon route.
- Hate Sink: He's perhaps the most despicable character in the game who isn't part of "those who slither in the dark".
- Laser-Guided Karma:
- Count Varley's abuse of his daughter resulted in her becoming a reclusive shut-in. After Edelgard takes the throne, he's forced into house arrest.
- Count Varley's goal was to marry Bernadetta off to Ferdinand to improve House Varley's status. If Bernadetta ends up with Ferdinand, she renounces her claim to House Varley, meaning that Count Varley gets what he wants, but doesn't benefit in the slightest.
- The abuse he afflicted on her, causing her extreme shut-in nature, led to rumors about her (that she was a scary shut in princess who made cursed dolls) that caused Ferdinand to beg his parents not to engage them as he was terrified of her, as revealed in their A+ support. His treatment of his daughter actually made her appear less marriageable.
The Minister of Military Affairs and Caspar's father.
- The Dreaded: Caspar is terrified of his father, and worries that his army can't possibly win if Count Bergliez takes the field.
- A Father to His Men: On Verdant Wind and Silver Snow, after the conquest of Enbarr, he apparently gives up his life so that his men would be spared.
- Four-Star Badass: At least according to Caspar.
- The Ghost: He never appears onscreen.
- Heroic Sacrifice: On Verdant Wind and Silver Snow, Count Bergliez sacrifices himself to save the lives of his men.
- Interservice Rivalry: He and Count Hevring, the latter of whom is the Minister of Domestic Affairs, can't stand each other.
- The Unfought: He's never actually faced on any of the routes that feature the Empire as an enemy.
The Three Nations of Fódlan - Holy Kingdom of Faerghus
The Holy Kingdom of Faerghus
Founded by Loog I, King of Lions in Imperial Year 751 after the Griffon War, the Holy Kingdom of Faerghus is an autonomous region to the north of Fódlan crowned by the Church of Seiros. Due to the harsh cold of the continent's frigid north, Faerghus's is a highly disciplined kingdom that values chivalry & its knights above all else. Students from Faerghus are placed in the Blue Lions.
- Decapitated Army: On the Crimson Flower route, despite Dimitri's death, this situation is averted, as Faerghus' military and populace then rally behind Rhea and the knights of Seiros instead, due to the country's long-standing support for the church.
- Faction Calculus: Balanced. Faerghus's knights rely less on raw power or numbers, preferring to balance out their forces.
- Fantastic Racism: A large portion of Faerghus' population despises the people of Duscur and treats them poorly. Relations had been bad for some time already, but they completely fell apart when King Lambert and many Kingdom officials and soldiers with him were horribly slaughtered during a diplomatic mission to Duscur. This assassination was blamed on the people of Duscur and came to be known as the Tragedy of Duscur. In truth the assassination was a high level conspiracy that utilized "those who slither in the dark" and took advantage of the pre-existing prejudices toward Duscur to make them the scapegoats and sow instability in the Kingdom. Said prejudices meant most in the Kingdom did not question that Duscur was to blame, despite the many things that did not add up about it. As Sylvain notes, the people of Duscur logically lacked the power and numbers needed to so completely slaughter the king's elite forces, and also lacked motive due to how Lambert was a reformist who advocated for the people of Duscur and therefore should have been the last person they would want to kill. Prince Dimitri's own testimony was ignored despite being the sole available witness and adamantly testifying that the people who attacked were not of Duscur.
- Fantasy Counterpart Culture: France. The Kingdom's treatment of knights & chivalry parallels how real-world France treated theirs.
- Fatal Flaw: Their Knight Templar tendencies. The people of Faerghus tend to view themselves as righteous, acting on nothing but zealotry to destroy those who disagree with them and falling straight into self-righteous hypocrisy, whether it be the Western Church, the Tragedy of Duscur, Lonato's rebellion, or the Dukedom. Notably, they are usually blind to it and don't recognize when they aren't acting nobly, unlike Dimitri who even at his worst is wracked with guilt over what he's become or on Crimson Flower where it's the desperation of being forced into a corner, with their loved ones, nation, and king on the line, that leads to the soldiers turning themselves into demonic beasts (even knowing what Dimitri would have to do even if they defeated the empire).
- Fighter, Mage, Thief: Fighter. The kingdom's military is disciplined and has a sense of chivalry instilled in them.
- God-Emperor: After Dimitri is slain by Edelgard on the Crimson Flower route, Rhea seizes leadership of Faerghus and becomes this to the kingdom.
- Grim Up North: Downplayed. Faerghus is able to sustain a functioning kingdom with little issues, but the cold environment forced them to adapt and made them vulnerable to sieges.
- Knight in Shining Armor: The Holy Kingdom has a proud tradition of knights, and chivalry is one of their most important values. Their banner is decorated with a knight atop a griffon.
- The Remnant: On the Crimson Flower route, the last remnants of the Faerghus army (led by Annette and Ashe, if they didn't defect) comprise about a third of the enemy composition of the final battle.
- Succession Crisis:
- King Lambert's assassination as a result of the Tragedy of Duscur briefly caused one of these, as while crown prince Dimitri survived he was deemed far too young and inexperienced to take the reins in a tumultuous time. The Grand Duke of Itha and Lambert's older brother Rufus (who was passed over the line of succession originally due to his lack of a Crest) took charge of the kingdom with the intent of passing it back to Dimitri once he came of age, though his rule has had its own share of problems thanks to the Western Church stirring up trouble.
- Depending on the route taken, this can potentially spring up again post-timeskip. Specifically in the routes where Dimitri is framed for the assassination of Rufus and forced to go on the run, with the major conspirator and court mage Cornelia becoming Faerghus' Puppet King.
- The Theocracy:
- It is called the Holy Kingdom of Faerghus, and was founded due to mediation from the church to end the war that Loog initiated to fight for its independence from the Adrestian Empire. That said, it is noted that the country's rulers are long-time supporters of the church and this automatically puts them at odds with the empire when Edelgard initiates her plan to destroy the church's grip on Fódlan.
- On the Crimson Flower route, Dimitri readily grants Rhea and the knights of Seiros asylum after the empire attacks the monastery, and even fights the empire's troops to the death to protect her. Despite his death, the country's support of the church also prevents it from collapsing, as its people and military then submit to Rhea's authority as archbishop.
- Undying Loyalty: The people of the country respect and adore serving both their royal family and the church. On the Azure Moon route, despite his long absence, the violent acts he committed, and the fact that he had been publicly declared a traitor by Cornelia, Dimitri receives a warm reception from his subjects when he finally returns to Faerghus to assume his responsibilities as king, having even openly rebelled beforehand when he returned. On the Crimson Flower route, after Dimitri is killed in battle by Edelgard, the populace then submit to Rhea's authority as the archbishop of the church. Despite Rhea's decision to burn Faerghus' capital to slow down the empire's advancement, the kingdom's soldiers still fight alongside the Knights of Seiros out of loyalty to their fallen liege.
Christophe GaspardThe son of Lord Lonato, and brother to Ashe.
- Posthumous Character: His death motivates Lord Lonato's actions, and is key to the supports between Ashe and Catherine.
- Unwitting Pawn: Ashe's support with Catherine reveals that while he wasn't involved with Duscur, he was part of another plot by the Western Church to assassinate Rhea, and she comments he was too naive and idealistic because he was easily swayed by their reasons.
Voiced by: Akemi Okamura (Japanese), Jessica Gee-George (English)
- Absolute Cleavage: She has a deep plunging neckline to compliment her enormous breasts.
- Break Them by Talking: When she's defeated, she reveals to Dimitri that it was his step-mother, the woman whom he saw as his own mother, who arranged for his father's assassination at Duscur for selfish reasons. The revelation greatly shakes an already unstable Dimitri, but didn't last quite long since Dimitri has also recovered a majority of his psyche thanks to Byleth and a previous incident.
- Chronic Backstabbing Disorder: On the Crimson Flower route, despite the Black Eagle Strike Force aiming to kill her, Cornelia still orders her Titanus warriors to kill Kingdom soldiers if they can, despite the fact said soldiers are her only other hope of surviving.
- Court Mage: Cornelia's position in the Faerghus, awarded for curing the plague that ravaged it.
- Defiant to the End: Even in her last moments, she spends her final act revealing uncomfortable truths to Dimitri to mess with him.
- Fallen Heroine: In the past, she was known as a holy woman that cured the plague that ravaged the country, though the real one was likely killed and replaced by Those Who Slither In The Dark, if she wasn't a plant from the beginning.
- Golem: On the Crimson Flower and Azure Moon routes, she commands several Titanus, giant metal warriors armed with BFSes that can fire Sword Beams. These are the very same mecha that guard Shambhala in the other two routes.
- Graceful Loser: Takes her death on the Crimson Flower route well, declaring how everything is going as planned as she dies.
- Impossibly-Low Neckline: Her revealing dress appears to be strapless, so it looks as if it could fall off from a single motion.
- Kill and Replace: Sometime after saving the kingdom from the disease afflicting it, Cornelia's personality completely changed. It's strongly implied she was replaced by a member of "those who slither in the dark," even being entrusted with tech only they use, and Arundel/Thales is pissed at her death, even retaliating against Edelgard on the Crimson Flower route for doing so.
- Lady of Black Magic: A cruel and self-serving Gremory, whose true allegiance lies with "those who slither in the dark", with powerful dark magic spells at her command.
- Ms. Fanservice: Falls into the series tradition of being the designated sexy mage antagonist. She wears a very revealing dress that exposes her back and cleavage, and has an enormous bust size.
- Older Than They Look: Pre-timeskip Sylvain speaks of her and considers how beautiful she was said to be back when she saved the kingdom. He then adds how long ago that was and that he expects her to be pretty old by now. He hasn't actually seen her at this point, but she clearly doesn't look her age. Of course we don't know how old the person who likely replaced her was, either, but it's not addressed if she gave some explanation to others for her seeming lack of aging.
- Pragmatic Villainy: When Dimitri's return inspires uprisings among the Kingdom citizens, Cornelia refuses to send troops to suppress them. It's not out of any sense of mercy to the people, but rather because she knows she has to confront Dimitri with every soldier she has and can't afford to send any elsewhere if she is to have any chance of winning.
- Recurring Element:
- While the franchise is no stranger to the 'corrupt older politician that sold out the good kingdom and ruling like a tyrant' which was kickstarted by Jiol, Cornelia is the first female example of this type of character; other differences include a lack of cowardice and being competent at her job.
- Cornelia is also an example of the Dark Lady Archetype, being a skimpy, evil sorceress, and is heavily implied to be part of "those who slither in the dark".
- Screw This, I'm Outta Here!: On the Verdant Wind route, Cornelia is The Unfought, opting to to abandon Faerghus after Edelgard's defeat.
- Theme Song Reveal: The second clue that she is part of "those who slither in the dark"? The fact the Shambhala theme initially plays for her before the battle.
- The Quisling: She's put in charge of the parts of Faerghus the Empire conquered, and wages war on the loyalists in the Empire's stead.
- The Unfought: She is fought and killed on the Crimson Flower and Azure Moon routes, but ditches the kingdom after Edelgard's death on the Verdant Wind route.
- The Un-Reveal: Unlike Thales, Solon, and Kronya, who have their identities and true forms revealed, Cornelia dies in her presumably disguised form and doesn't revert back when she dies.
- You Have Outlived Your Usefulness: On the Crimson Flower route, Edelgard opts to have her killed during the assault on Arianrhod, viewing it as a useful preemptive first strike against "those who slither in the dark".
Glenn FraldariusThe firstborn son of Lord Rodrigue, Felix's older brother, and fiance of Ingrid.
- The Ace: Rodrique states that at the age of 15, he was already serving the King and Dimitri as a loyal knight.
- Alternative Character Interpretation: An In-Universe example. Felix, Dimitri, Ingrid, and Rodrigue have conflicting opinions on him due to the nature of his death. Rodrigue and Ingrid see him as a heroic figure who died doing what he thought was right, and that his death was noble. Dimitri sees him as a tragic and loyal knight whose death was a Senseless Sacrifice, and not heroic. Felix sees him as being a Lawful Stupid fool who gave up his life for a pointless reason as a result of his ideals. Nobody is painted as being right or wrong for their outlook on it, and Rodrigue concedes that Felix has a point about his frustration with it but argues Glenn would have felt horrible for running away.
- Always Someone Better: To Felix, as Felix tells Byleth in their A support how he was never able to best him before he was killed.
- Chronic Hero Syndrome: According to Rodrigue, Glenn wouldn't have been able to forgive himself if he survived the Tragedy of Duscur through cowardice and instead chose to die protecting Dimitri.
- Cynicism Catalyst: His death was this for Felix and Ingrid, causing Felix to become cold and angry, and causing Ingrid's Fantastic Racism towards the people of Duscur to manifest.
- Heroic Sacrifice: He died protecting Dimitri during the Tragedy of Duscur.
- Knight in Shining Armor: By all accounts he was this, given how everyone talks about him posthumously.
- Posthumous Character: Died in the Tragedy of Duscur.
- Small Role, Big Impact: He's a Posthumous Character whose physical appearance is never revealed and has only one known truly noteworthy deed to his name, yet his Heroic Sacrifice at the Tragedy of Duscur and the fallout as a result contributes to no less than four different characters' current outlooks (Dimitri, Felix, Ingrid, and Rodrigue).
Class: Great Knight
Voiced by: Ryo Sugisaki (Japanese), Michael Sorich (English)
- Alas, Poor Villain: Defied. While he's relatively sympathetic, some of the knights around the monastery say that mourning Gwendal's death would be an insult to the way he lived his life.
- Blood Knight: He wishes to fight to the death in combat, and is unforgiving to his enemies even if they were kids. On the Azure Moon route, he even betrays the kingdom and fights against Dimitri's forces because he thinks they'll be a good challenge.
- A Good Way to Die: Is happy when he meets his end, thanking Byleth's army for killing him.
- My Master, Right or Wrong: As a true knight, he and others muse that he would have been happy to fight for whatever side his master chose.
- Overprotective Dad: Not seen in game, but according to Ingrid, he was not happy when Sylvain hit on his daughter.
- Red Baron: Known as the Gray Lion.
Lambert Egitte Blaiddyd
Voiced by: Shinobu Matsumoto (Japanese), Patrick Seitz (English)
- Childhood Friends: Much like their sons Dimitri and Felix, Lambert and Rodrigue grew up together and attended the Officers Academy alongside each other.
- Former Teen Rebel: According to Rodrigue, he and Lambert used to sneak out of lectures during their days at the Academy. Evidently, though, both men grew up into heroic and noble figures.
- The Good King: By all means he was one, even attempting a major political reform that would benefit the people of Duscur.
- Love at First Sight: He was apparently taken with Patricia the moment he saw her, according to Dimitri.
- Nice Job Breaking It, Hero!: Assuming Dimitri's memory of events is correct, then Lambert's last words to his son was a plea to avenge their deaths. Boy, did he take that to heart.
- Off with His Head!: How he died, according to Dimitri. This is the reason Dimitri is so focused on beheading the Flame Emperor, once he believes they had a hand in the Tragedy of Duscur.
- Posthumous Character: Assassinated during the Tragedy of Duscur.
- Recurring Element: Serves as the 'long dead father of the Lord character' archetype started with Cornelius for Dimitri, who's the closest to Marth among the three Lords.
- Uncanny Family Resemblance: If he grew a beard and kept his hair neater, post-timeskip Dimitri would look exactly like his father.
- Youngest Child Wins: Like Sylvain, he is the second son of his family who became heir because he had a Crest. His older brother, Rufus, was passed over in the line of succession for Faerghus' throne because he lacked a Crest, and was instead given the title of Grand Duke of Itha.
Lord Lonato Gildas Gaspard
Voiced by: Kazuhiro Anzai (Japanese), Dave B. Mitchell (credited as Raymond K. Essel) (English)
- Anti-Villain: Most people who know Lonato say he's a good man, and he's rebelling because he believes his son was wrongfully executed by the Church of Seiros. He even expresses remorse over fighting Dimitri.
- Fog of War: Intentionally causes this in his battle, with a Gaspard Commander creating the fog via magic.
- Genius Bruiser: Aside from being a skilled warrior, talking with Ashe reveals Lonato taught him all about various herbs, such as identifying them and how to make medicines out of them.
- Good Parents: Lonato loves Ashe as if he were his own blood, teaching him to read and offering him all the benefits of nobility despite Ashe's lowly birth. This is after he caught a young Ashe snooping around his mansion looking for valuables to steal. Thus his actions against the Church of Seiros shock the poor boy.
- Revenge: Desires revenge against the Central Church for executing his oldest son Christophe for the Tragedy of Duscur. Specifically Catherine herself, who is the one who detained his boy.
- Revenge Before Reason: Lonato got so caught up in anger against the Central Church and Catherine he allowed himself to be set up by the Western Church, the ones truly responsible for the incident Christophe got involved in and was executed for.
- Undying Loyalty: His men have this towards him, with many generics declaring their loyalty to him.
- Unwitting Pawn: The Western Church uses his grief over his eldest's death to make him attack the Central Church. Making it even more tragic because they were responsible for why Christophe got executed having swayed him into assisting in a different plot to assassinate Rhea.
- Villain Has a Point: For as many lives as he ends and jeopardizes to get back at the Central Church, he's correct to believe they executed Christophe under false pretenses. In truth, he was killed for assisting in an assassination attempt on Rhea, and not for any involvement in the Tragedy of Duscur.
- Well-Intentioned Extremist: Rises a rebellion against the Central Church because he rightly believes it lied about the reasons for his son's execution, thus in his mind making the entity hopelessly corrupt. Catherine argues it was necessary to avoid further public panic and disorder in the wake of the king's murder, that the people didn't need to know Rhea herself was now being targeted.
Miklan Anschutz Gautier
Class: Armored Knight → Black Beast
Voiced by: Daisuke Endou (Japanese), Armen Taylor (English)
- Asshole Victim: His transformation into a beast was something unexpected and a horrible way to go, but given how he's a thief who bullied Sylvain for most of his life, it's hard to feel sorry for him.
- Big Brother Bully: His resentment toward Sylvain resulted in him bullying him growing up. One of the worst instances was pushing Sylvain down a well and then leaving him there.
- Cain and Abel: Has a murderous grudge against his younger brother Sylvain.
- For the Evulz: His gang of thieves raids several villages, apparently for fun. While Dimitri can understand stealing in order to survive, even if he disapproves of it, he considers this unforgivable.
- Freudian Excuse: He was denied his inheritance as a first-born just because he wasn't born with a Crest, something he had absolutely no control over. This prompted his murderous resentment that eventually led to him being disowned and then becoming a bandit.
- Good Scars, Evil Scars: He's the leader of a gang of bandits that steal a Hero Relic to aid in their plundering of villages. Unlike his smooth-skinned younger brother, Miklan has a large nasty-looking scar running down his face and a smaller one on his chin.
- Green-Eyed Monster: Envied Sylvain all his life, blaming every problem on him due to his brother bearing a Crest in his stead.
- I Just Want to Be Special: Wanted the power of the Crests or their weapons for himself after being denied it by his birth.
- Karmic Transformation: Wanted to be special and so ended up transforming into the Black Beast, a special form of monstrosity, from misusing a Relic weapon without a Crest.
- Lone Wolf Boss: He's the only enemy in Part 1 who isn't connected in some way to the Flame Emperor or "those who slither in the dark".
- Tarot Motifs: Death, which signifies change. He certainly changes alright, and his transformation into a Black Beast leads to his own death. Interestingly, his Beast form has a marking on the face that has 'DEATH XIII' and the Gautier Crest on it, implying that it was completely intentional.
- The Unfavorite: Margrave Gautier desired only a child with a Crest to be his heir (as had been the custom for the family for ages, as being able to wield their Relic weapon was essential for defending their land). Miklan being born without it already made him a disappointment, but Sylvain being born with it just cemented Miklan's status as the eternal unfavorite.
- Wake-Up Call Boss: His second form is a brutal wake-up, introducing monster enemies and their tactics. He's almost certain to plaster Gilbert, and is likely to take out one or two of your own students if you're not careful.
- You Could Have Used Your Powers for Good: Edelgard notes that despite not possessing a Crest, Miklan managed to make something of himself by becoming the leader of a successful group of bandits, demonstrating that he had fine leadership and strategic skills and charisma. She scorns the prevailing idea among nobility that Crests are the be-all, end-all of potential, and wonders what he could have done as a noble with proper training.
Patricia von ArundelThe younger sister of Volkhard von Arundel. At different times in her life, she served as the empress of the Adrestian Empire, during which time she gave birth to Edelgard, and Queen Consort of the Holy Kingdom of Faerghus, becoming Dimitri's stepmother.
- Deal with the Devil: Queen Patricia wanted so badly to see her own daughter again, she sacrificed the King (Dimitri's father) by conspiring with Cornelia to cause the Tragedy of Duscur to make it happen. As for what happened to her and her daughter, see below.
- First Love: Doubles as Love at First Sight, but Ionius IX was this for her. However, by the time they met, he was already in a political marriage, which resulted in her being one of his paramours instead of his wife. Despite that and her exile from the capital, Edelgard believes they truly did love one another.
- Good Stepmother: According to those who knew her, she seemed to be this to Dimitri, and apparently cared for him dearly, despite not being his biological mother. However, on the Azure Moon route, after being defeated, Cornelia claims that Patricia never loved Dimitri at all and instead conspired with "those who slither in the dark" to orchestrate the Tragedy of Duscur, just so she could return to the Adrestian Empire and reunite with Edelgard.
- Love at First Sight: According to Edelgard and Dimitri, their respective fathers both fell for Patricia the moment they saw her.
- Posthumous Character: Died during the Tragedy of Duscur. Or so it seems...
- What Happened to the Mouse?: She's widely believed to have died at Duscur when her carriage was attacked. On the Azure Moon route, it's revealed she helped Cornelia start the massacre in Duscur. Someone involved in the events at Duscur confirms that they had strict orders to avoid her carriage. Furthermore, as Thales impersonated her brother, it raises further questions as to what became of her.
Lord Rodrigue Achille Fraldarius
Voiced by: Taira Kikumoto (Japanese), Jake Eberle (English)
Class: Holy Knight
- Childhood Friends: Much like their sons Felix and Dimitri, Rodrigue grew up alongside Lambert and attended the Officers Academy with him.
- Combat Medic: As a Holy Knight, he's got access to the area-of-effect heal Fortify spell and the offensive Faith magic spell Aura. In his appearance as an allied, but uncontrollable unit on the Azure Moon route at Aillel, he's there to fight the forces of House Rowe and keep Dimitri healed up as well.
- Former Teen Rebel: According to Rodrigue, he and Lambert used to sneak out of lectures during their days at the Academy. Evidently, though, both men grew up into heroic and noble figures.
- Heroic Sacrifice: He intercepts a fatal knife blow from Fleche in her attempt to kill Dimitri on the Azure Moon route. His death and the entire event becomes a huge wake-up call for Dimitri.
- Heroic Self-Deprecation: Rodrigue doesn't think too highly of himself at times; in a conversation with Byleth on the Azure Moon route, he calls himself a "failure of a man," and laments his own mistakes of turning Felix against him by speaking carelessly about Glenn's death.
- Innocently Insensitive: Rodrigue deeply regrets insisting to Felix that Glenn died a heroic death, as it embittered Felix towards both Rodrigue and the concept of chivalry. Not helping the situation is that this is implied to be his way of coping with his son's death, making it all the harder for both when it was his own way to rationalize it.
- Knight in Shining Armor: He does his best to live by this ideal.
- Light 'em Up: He's no slouch when it comes to faith magic, his Aura can deal an immense amount of damage to his foes.
- Like Father, Unlike Son: While Glenn is suggested to be cut from the same cloth, Felix is an anti-social swordsman with reason magic potential, while Rodrigue is a personable Knight in Shining Armor that uses faith magic.
- Nice Guy: Unlike his son, who's significantly rougher around the edges, Rodrigue is generally a polite and friendly individual, as shown in his interactions with Dimitri, Byleth and their allies.
- The Paladin: Although his class itself is Holy Knight, he fits the role as a Knight in Shining Armor with powerful light magic.
- Parental Substitute: To Dimitri, whom he calls a second father, and has a much better relationship with than his own son.
- Parents as People: He tries to be a good parent, but his relationship is strained with Felix over Glenn's death, and he even admits he shouldn't have said that Glenn died like a true knight as it wasn't comforting. He even appreciates you understanding him. However, when he dies on the Azure Moon route, Felix is devastated and demands that Dimitri not let the death go in vain.
- Red Baron: He's known as the "Shield of Faerghus."
- Skewed Priorities: Felix accuses Rodrigue of caring more about honoring Lambert's memory by protecting a village important to the late king than about saving the lives of his people.
- Suspiciously Similar Substitute: Storyline-wise, in Azure Moon he serves as one for Verdant Wind's Judith Daphnel post-timeskip. Rodrigue and Judith are both important lords of their respective nations and are both actively involved in the fight against the Empire. Like Judith, Rodrigue agrees to send reinforcements by way of Ailell, the Valley of Torment in the second mission of their route and thereafter becomes an important but unplayable ally. They're also both tied to their route's respective lords as parental substitutes and/or mentors. However, the main difference is that while Judith will survive Verdant Wind, Rodrigue does not survive Azure Moon. And both are required to die on Crimson Flower.
- What Happened to the Mouse?: On the Verdant Wind route, once the timeskip occurs, he is never mentioned again or appears. As the Kingdom is nearly steamrolled by the Empire in all routes but the Crimson Flower route, he likely died in battle. This is implied by Felix should you have him recruited in the route, mentioning that he hasn't heard a word from his father and the silence is worrisome.
- What the Hell, Hero?: Should Felix join the Black Eagles and confront his father on the Crimson Flower route, the latter will not mince his words about his son's decision and declares his intent to kill him. By the end of the route, it's made clear Felix agrees with him.
- You Gotta Have Blue Hair: Like his son, he's got dark blue hair.
The Three Nations of Fódlan - Leicester Alliance
The Leicester Alliance
The youngest and smallest of the three nations. The Alliance is a loose conferdation of noble houses who refuse to bow to any king or emperor located to the east of Fódlan. However, they allow one family to lead them: House Riegan. Each house's territory is technically an autonomous region, though they all swear allegiances of loyalty to each other. Leicester students are assigned into the Golden Deer.
- A House Divided: Post-timeskip, due to the Chronic Backstabbing Disorder that the country's nobles suffer from, half of them are quick to support the Adrestian Empire when it declares war on the church, which basically fractures the Leicester Alliance from within. Claude is forced to effectively pit the two sides (one for the Empire, the other for the Holy Kingdom) against each other in order to maintain their neutrality.
- The Alliance: A loose coalition of territories united under a single banner. It's deconstructed in that the nobles ruling the Alliance are far more concerned with their own personal advancement than the welfare of the nation as a whole; two of the three Part I paralogues involving the Golden Deer have you put down an ambitious and unscrupulous noble's attempts to gain more power, and in Part II the country falls apart when Adrestia declares war on everyone.
- Blue Blood: Unlike their neighbors, the Adrestian Empire and Holy Kingdom of Faerghus, they lack royalty and are governed by a coalition of nobility who refuse to swear fealty to any royal.
- Chronic Backstabbing Disorder: While the nobles of the other nations have shades of this, it is most pronounced in the Leicester Alliance. Despite the vows of loyalty its nobles swore to each other, they are ultimately portrayed as opportunistic and more invested in furthering the interests of their own houses rather than the country as a whole.
- Faction Calculus: Subversive. Leicester's military is looser than the that of the other two nations, consisting of more peasant levies.
- Fantastic Racism: Many in the country are not particularly fond of Almyrans due to many years of war and border skirmishes.
- Fantasy Counterpart Culture:
- The various Merchant Republics of Italy, and the Kingdom of England. Their refusal to be led by a king and a quarter of the playable Golden Deer characters being the children of merchants draws this parallel. Additionally, a lot of the place names are taken straight from England, the Alliance being known for the use of the bow, and the presence of a fortified wall along the border add to the real life comparison with England. In addition, many of the well known characters from the alliance are named after a Shakespearean play, King Lear.
- The country's governing system, comprised of autonomous states with their own hereditary rulers, and all of the rulers participating in a forum to decide on the governance of the country as a whole, calls to mind federal monarchies such as Malaysia and the United Arab Emirates.
- Fighter, Mage, Thief: Thief. A lot of their military are hunters proficient with bows.
- Hereditary Republic: Despite it being explicitly stated that the country is not a monarchy, its governing positions are nonetheless generally hereditary, such as membership of the governing Roundtable, which includes the country's overall leader. However, a noble house in the Roundtable can lose its position through loss of standing among its peers.
- I Fight for the Strongest Side: This is the main reason half of the country's noble houses sided with the Adrestian Empire in the face of the possibility that the empire may attack. They reasoned that their country cannot capably fight back and thus viewed capitulation to the empire as the only way to survive.
- It Is Pronounced "Tro-PAY": Leicester is pronounced the British way as "Lester," not "Lai-ches-ter." One of the most prominent noble families is House Gloucester, which is similarly pronounced "Gloster".
- Keystone Army: The coalition of noble houses that comprise the country is so fragile that without a unifying figure to lead them, they will instantly fall apart due to infighting. On the Crimson Flower route, Claude's death or desertion leads to the entire country being too weak and disunified to resist the Adrestian Empire's forces.
- Mountain Man: The Alliance's geography is quite mountainous.
- Succession Crisis: One occurs for the leading House Riegan in the Imperial Year 1179, a year before the events of the game, when Godfrey, Claude's uncle and the family's heir, passes away unexpectedly, and his sister is unaccounted for. This is resolved when Godfrey's father, Duke Riegan, legitimizes his Heroic Bastard grandson Claude. Prior to this, Holst was viewed by many as the favorite to suceed Duke Riegan.
- Thicker Than Water: This is the reason for the country's general disunity and lack of ability to put up any efficient resistance to outside aggression. Despite agreeing to mutually defend each other, the noble houses that comprise the Leicester Alliance are more loyal to their own interests than to the country's welfare as a whole.
- We ARE Struggling Together: Despite the fact that aggression from the Adrestian Empire threatens the country's existence, it is difficult to get its nobles to mount a unified resistance when half of them think that it's better off to capitulate to Edelgard rather than fight. The best that Claude can accomplish is to try and keep the country from fracturing at the seams while giving off the impression of neutrality.
Class: Mage → Cavalier/Warlock
Voiced by: Ryou Nishitani (Japanese), Doug Erholtz (English)
- Butt-Monkey: He's treated as a joke by the Golden Deer students before the timeskip; combined with his arrogance, they end up making a fool of him every time. When Claude faces him and Acheron is at his most haughty, Claude reveals they've set his castle on fire, and turns his taunt about the Alliance collapsing back at him.
- Cavalry Betrayal: Downplayed; he's sent to reinforce Judith on the Crimson Flower campaign, but the moment he sees his fellow reinforcements fall he decides to cut tail and run for his life, resulting in Judith being forced to retreat and ultimately be cut down.
- Dirty Coward: On the Crimson Flower route, he runs away and leaves Judith to die if Leonie/the generic Paladin who replaces her is killed.
- Embarrassing Nickname: He's nicknamed "The Weathervane" for his political opportunism.
- Fair Weather Friend: "Friend" is pushing it, but all the other Leicester nobles are still nominally allied to him despite his infamous opportunism. Lord Gloucester opts to spare him after he incites a violent conquest of his territory, considering it too inconvenient just to kill him. Claude, however, isn't so restrained.
- The Friend Nobody Likes: In a country characterized by its nobles suffering from Chronic Backstabbing Disorder, he stands out in particular for his political opportunism, which garners him the distaste of practically every other noble house in the nation. It is particularly notable on the Verdant Wind route, where Claude doesn't even attempt to convince him to join the other noble houses in a united offensive against the Adrestian Empire. Instead, Claude simply remarks that he is "nothing but a nuisance" and should be shown no mercy for siding with the empire.
- I Fight for the Strongest Side: He is noted for being one to gravitate towards power, and either sides with the Adrestian Empire on the Azure Moon/Verdant Wind/Silver Snow routes, or flees from its forces on the Crimson Flower route.
- Irony: Despite his infamous opportunism, he invariably ends up siding with the losing team in every route and will likely be unceremoniously cut down for it.
- The Quisling: In all non-Crimson Flower routes, he sides with the empire and ambushes the resistance army while they are battling Ladislava.
- Recurring Element: The aforementioned Cornelia isn't the game's only token 'corrupt noble that backstabbed their faction for selfish gain' like Jiol; Acheron also fulfills that role, especially for the Golden Deer (and he'll also betray them when seen in other routes).
- Screw This, I'm Outta Here!: On the Crimson Flower route, he resents having to obey Claude's orders, and if the other general defending the Great Bridge of Myrddin dies, he flees with his units.
- Tempting Fate: Brags about his fair-weather nature when engaged in combat, before quickly worrying if he's in for a beating. Given his lackluster stats, he is.Acheron: As they say, if you can't beat them, join them. I'm not in for a beating, am I?
Holst GonerilThe head of House Goneril, and older brother of Hilda. Charged with defending the Leicester Alliance from the neighboring kingdom of Almyra, he earned a reputation as the Alliance's greatest general.
- The Ace: Hilda describes her brother as perfect at everything, and he's considered the Leicester Alliance's greatest general.
- Always Someone Better: Toward Hilda. Hilda describes him as such."I have a very impressive big brother. I'm not just saying that. He's strong, smart, nice. He's basically perfect."
- An Axe to Grind: Implied; he commands an battalion of axe wielders that you can fight in the arena, and considering his sister also uses an axe, it's very likely he wields an axe.
- Big Brother Instinct: Hilda describes her brother as clingy and overprotective, and he is constantly sending her letters worrying about her life.
- The Ghost: While Hilda, Claude, and Lorenz mention him quite frequently, he never makes a personal appearance.
- Nice Guy: According to Hilda, he's always kind and hates to disappoint people.
- Tall, Dark, and Handsome: According to Hilda.
- The Worf Effect: At the end of the Verdant Wind route, he is easily defeated by Nemesis. While he survives, the fact how the characters put him as a high profile warrior shows how dangerous Nemesis is despite just being brought back from the dead.
- Worf Had the Flu: In Hilda's paralogue and Edelgard's post-timeskip after the fall of the Leicester Alliance, they're forced to take command of his position because he's suffering from severe food poisoning. Hubert describes it as him being incredibly pale and smelling bad.
Lady Judith Daphnel
Voiced by: Yoko Soumi (Japanese), Rachel Robinson (English)
- Abdicate the Throne: Before the events of the game, she willingly gave up her seat as one of the five ruling lords of the Alliance.
- Boobs of Steel: She's a celebrated heroine of the Alliance and is quite well-endowed.
- Killed Off for Real: In the Crimson Flower route, she has to be killed to progress.
- Red Baron: Hailed as the "Hero of Daphnel."
- Royal Rapier: Befitting her status as a noble, she wields a rapier in combat and is accompanied by a battalion of duelists.
- Screw This, I'm Outta Here!:
- On the Crimson Flower path, she will make a hasty retreat if the battle is turning south for her. It's to no avail however as the map requires that she be killed before she can escape.
- Claude tells this to her again on the Verdant Wind route. Unlike on the Crimson Flower route, she never has to resort to running away.
- Suspiciously Similar Substitute: Storyline-wise, in Verdant Wind Judith serves as one for Azure Moon's Rodrigue Fraldarius post-timeskip. Judith and Rodrigue are both important lords of their respective nations and are both actively involved in the fight against the Empire. Like Rodrigue, Judith agrees to send reinforcements by way of Ailell, the Valley of Torment in the second mission of their route and thereafter becomes an important but unplayable ally. They're also both tied to their route's respective lords as parental substitutes and/or mentors. However, the main difference is that while Rodrigue will always die on Azure Moon, Judith will always survive Verdant Wind. And both are required to die on Crimson Flower.
- Underestimating Badassery: On the Crimson Flower route, she notes she was told to run by "the boy" (Claude) if she was in danger but disregards it, believing she can certainly hold out until reinforcements arrive. The Black Eagle Strike Force proves her wrong, prompting her Screw This, I'm Out of Here! moment.
Class: King of Liberation
Voiced by: Naomi Kusumi (Japanese), Jamieson Price (English)
Seiros' opponent in a war ages ago. He once wielded the Sword of the Creator as well as the same Crest that Byleth possesses.
- Back from the Dead: Using Sothis's remaining parts, "those who slither in the dark" created a second Sword of the Creator and resurrected him to be their trump card.
- Dark Is Evil: Wields a Dark version of the Sword of the Creator using what's left of Sothis remains, though powered by two of her childrens' Crest Stones in place of her own.
- Evil Counterpart: To Byleth, made especially apparent after he returns as the Verdant Wind route's final boss. Both were initially mundane leaders of human parties who were suddenly bestowed a special connection with the Goddess, as symbolized by the Sword of the Creator. Both return after a long period of absence to lead their now legendary parties once more. However, while Byleth has a legitimate connection with the Goddess forced upon them at birth and eventually becomes a benevolent teacher and thoughtful warrior, Nemesis stole the remains of Sothis to acquire the Sword of the Creator and the Crest of Flames, cares nothing for the mummified husks of his old companions, and seeks nothing more than to conquer Fódlan and crush Seiros.
- Fallen Hero: According to Seteth, Nemesis was once a revered king of humanity that was gifted the Sword of the Creator by the Goddess to combat the wicked gods. He succeeded, but the power corrupted him and forced Seiros to put him down. In truth, he was a bandit who, under the advice of "those who slither in the dark," stole the remains of Sothis, acquired the Sword of the Creator using said remains, and slaughtered her children to make Crests out from their hearts. While he did liberate the continent from invaders, the atrocities he committed to do so would come back to bite him in the ass.
- Final Boss: He's the final enemy of the Verdant Wind route.
- From Nobody to Nightmare: He was originally a bandit who, seeking to save Fódlan from invaders during a time of crisis, started listening to "those who slither in the dark," leading him to plunder Sothis' tomb and carry out a massacre on her children using the Sword of the Creator made by Agarthan technology. The bodies of the Children of the Goddess were used to create more Relic weapons and used to liberate the continent from the invaders and resulted in Nemesis becoming a King. Eventually, Seiros, Sothis's daughter, would find out that he was the culprit behind the atrocities and manipulate some of his allies into infighting, as well as gain human allies of her own to fight against his army (namely giving her blood to the first Adrestian Emperor). In a conflict that lasted the better part of 100 years, she would eventually defeat him in battle herself. On the Verdant Wind route, however, that isn't enough to keep him down, as "those who slither in the dark" resurrect him to serve as their trump card.
- Generic Doomsday Villain: He doesn't show much personality beyond "Crush. Kill. Destroy!", a grudge against Seiros, and the belief that single combat is more honorable.
- Greater-Scope Villain: His actions started the entire plot of Three Houses: By murdering Sothis and her children, Nemesis is the reason why the "Heroic Relics" were created, including his Sword of the Creator, by murdering Sothis and her children and using their remains to create those weapons as well as their Crests. As a result, Seiros was traumatized by grief, and later, unwilling to move on, tries to create a suitable body to bring her mother back.
- Hypocrite: He calls Byleth and Claude cowards for not facing him one on one while spending the entire battle hiding behind the 10 Elites, not to mention he was only able to obtain his power in the first place because he slipped into a little girl's room and murdered her in her sleep.
- Ironic Name: Nemesis is named after the Greek goddess who exacts vengeance on those who become arrogant before the gods. This Nemesis was given his power supposedly to destroy gods or not and was ultimately killed in an act of vengeance.
- Jack-of-All-Trades: He has a little experience in everything except faith magic as the Final Boss of the Verdant Wind route.
- Karmic Death:
- Long before the game begins, he's killed by Seiros, the daughter of Sothis, the one he murdered to make his Sword of the Creator.
- On the Verdant Wind route, he's killed by Byleth (a person enhanced by Sothis's soul) with the Sword of the Creator (the weapon made with Sothis's corpse).
- Keystone Army: When resurrected, he serves as this for the rest of the undead with him. While Nemesis appears to retain some semblance of his mind and memories, Claude notes the 10 Elites and other undead soldiers are essentially just his puppets, and when Nemesis is defeated, they all crumble into dust.
- Leitmotif: "God-Shattering Star" plays during the final battle with him on the Verdant Wind route.
- Long-Lived: Before his death, if the timeline is correct he is almost 150 years old by the time he faces Seiros and is still as fit as ever. This is due to him being a first-generation Crest-bearer (who live for centuries with little or no visible aging past adulthood or whatever point they received their Crest).
- Multiple-Choice Past: There are three different versions of the story of his life that the player hears over the course of the game.
- The official Church version is that Nemesis was a hero of men who received the Sword of the Creator as a divine gift and defeated evil gods in battle, but was corrupted by his power and had to be put down by Saint Seiros and the 10 Elites.
- On the Crimson Flower route, Edelgard gives the version of the story passed down through each emperor. In this version, he was an all powerful king whose war with Seiros was motivated by what type of ruler should lead mankind, and that Seiros killed Nemesis to take power in Fodlan. It's also stated that the relics were created by mankind.
- On the Verdant Wind route, Rhea states that Nemesis was a bandit who murdered the goddess Sothis and created the Sword of the Creator out of her remains, and then went to Zanado to massacre the Nabateans living there and create the Heroes' Relics from their corpses. An enraged Seiros was one of the sole survivors of the event and killed him in revenge, and then rewrote history to make sure the remaining Nabateans wouldn't be killed to make more Heroes' Relics. Arundel, aka Thales, an actual Agarthan, refers to him as a "thief", supporting this version of the story.
- No-Holds-Barred Beatdown: Is on the receiving end of Seiros' punches and kicks after he disarms her, just before he gets stabbed to death.
- Oh, Crap!:
- His eyes visibly widen in fear when Seiros reminds him of what transpired at the Red Canyon. This turns out to be because he never expected any survivors from his slaughter of Sothis and her children, and that Seiros has now come to deliver swift karma on him.
- Nemesis visibly looks surprised and has sweat on his face when he realizes that Byleth wields the Crest of Flames and the Sword of the Creator.
- One-Man Army: The opening cutscene shows him cutting through Seiros' soldiers like wheat.
- Proud Warrior Race Guy: A dark take on this since he's a bandit king with all that implies yet in the final cutscene of Verdant Wind, Nemesis expresses disgust with Byleth and Claude that they're facing him together, denying Nemesis a one-on-one duel. Byleth and Claude brush it off and take him down by working together and coordinating their attacks. This harkens back to the opening cutscene where he's shown engaging Seiros in such a duel. That didn't work out for him either.
- Recurring Element: Nemesis is effectively the traditional Medeus with his Arch-Enemy Seiros. He is an incredibly powerful villainous warrior who is slain by the hero in the backstory, which ushers in an age of peace for the world. However, it is the goal of the villains to resurrect him in order to have him take revenge on the descendants of those who defeated him and rebuild his reign. Additionally, he used to be a bandit with simple motives of conquering and showing off his strength. Had Seiros been the protagonist of the game, he would've been a take of the 'starter bandit' archetype that began with Gazzak; so he ended up being a take of a Gazzak that ascends into a Medeus.
- Red Baron: Was known as the "Liberation King" in life.
- Sealed Evil in a Can: "Those who slither in the dark" keep him contained and unconscious until he is released through unknown means during the Verdant Wind route. Rhea/Seiros allude to his revival with the words, "the seal has been broken," suggesting that she contained him after failing to kill him.
- Walking Spoiler: He's shown in a cutscene at the beginning of the game, and referenced a few times throughout the story, but the truth behind Seiros's quest for vengeance, as well as the fact that resurrecting him is the ultimate goal of "those who slither in the dark" (which they succeed at doing on the Verdant Wind route), is one of the game's key plot twists that is only revealed on the Verdant Wind route.
- Worthy Opponent: Refuses to acknowledge Claude and Byleth as this because they refuse to fight him 1v1, and team up against him.
Class: Saint/The Immaculate One
Voiced by: Kikuko Inoue (Japanese), Cherami Leigh (English)
A Lady of War who fought against Nemesis ages ago. The central figure of worship in the present Church of Seiros. Unbeknownst to her followers, she was the demigod child of the Goddess, and founded the Church primarily as an act of personal hatred against Nemesis, who stole her mother's remains and killed her brethren. She's still around though, and as it turns out, her mother's end did not have good effects on her mind.
- Ax-Crazy: In the opening, and if Byleth betrays her for Edelgard.
- Big Bad: She is this on the Crimson Flower route, principally because she goes insane and can no longer be reasoned with. Seiros has been running the Church unopposed as Rhea for many years (it's unclear at what point Seiros faked her own death and then returned under the identity of Rhea). In the process, she's distorted the continent's history, kept it mostly sealed off from the rest of the world, perpetuated the Crest system by spreading the lie that Crests were gifted from the Goddess herself, and worked to resurrect her mother through any means necessary.
- Body Horror: Unlike the sleek and pristine form it is in the other routes, her Immaculate One form at the end of the Silver Snow route looks like she's rotting, possibly as a way to indicate just how out of control she is.
- Contrasting Sequel Antagonist: Previous Fire Emblem dragon antagonists were mostly male and some were even driven mad or worse, such as Duma and Anankos, due to degradation. Seiros went mad due to the loss of her mother and a severe case of misanthropy. In the Crimson Flower route, her madness worsens due to Byleth's betrayal, whereas in Silver Snow, drawing upon too much power drives her insane. Unusually, she is possibly the only Fire Emblem dragon boss who can be saved through Love Redeems if the player chooses to S-Support her.
- Dark Messiah: She admits in her S-Support with Byleth that her original intention with the Church was to keep the peace in Fódlan and to avoid another costly war, but states that creating a false history and otherwise using the Church to revive her mother was a step too far and may have directly caused the situation they found themselves in.
- Death Glare:
- Towards Nemesis in the opening if looks could kill, he'd already be a black stain on the ground.
- Gives another to Byleth should they choose to side with Edelgard in the Holy Tomb. Though this one is especially discomforting since this is the moment when we see Rhea "snap" back into Seiros.
- Dissonant Serenity:
- She stands unflinching and perfectly-still even as her own personal guard dwindles around her, only showing emotion when the time comes for her to fight Nemesis or Byleth/Edelgard.
- She maintains some degree of this in the BE route despite treading the fine line of insanity for the past 5 years. Of course, this vanishes entirely once she reprises her warrior persona and onwards.
- Fallen Hero: Saint Seiros was a straight-up Big Good back in the War of Heroes. In the present, she's much more ambiguous as Rhea, and dons the Seiros identity as an antagonist.
- Faking the Dead: Though historical accounts marks her as a deceased figure, she, in reality, is still alive, continuing to control the Church and her efforts to resurrect her mother as Rhea.
- Final Boss: In both the Crimson Flower and Silver Snow routes; on the Crimson Flower path, she's been insane for five years ever since Byleth's betrayal, and in the Silver Snow path, Rhea drawing on her powers too often and too deeply awakens her rage, consuming her.
- To Dimitri, being what would happen if he did achieve his vengeance but found it didn't solve any of his personal problems. Seiros is still trapped in the past even a thousand years on, unable to trust even those she is closest to with the full truth.
- She is also this to Edelgard. Both are characters who are deeply haunted by their pasts and have led/are leading revolutions to change the world that wronged them. While Edelgard's trauma deeply motivates her to abolish the old system and create a new future where no one else will have to suffer like her, Seiros' trauma leads her to want to maintain the power structure of the status quo to prevent another war like the one that destroyed Fódlan in the past. She also seeks to resurrect her mother to heal from her own suffering, having not been able to truly let go of her.
- Giant Space Flea from Nowhere: Her berserk Immaculate One form at the end of the Silver Snow route has little buildup or explanation as to why she suddenly loses control in such an extreme manner except for a throwaway line about how much of her power she used to stop Thales' Taking You with Me attack.
- Good Old Fisticuffs: After being disarmed, she manages to fight Nemesis head-on with only her fists.
- Made of Iron: Even for a demigod dragon, the woman is absurdly tough. Repeated direct hits from magitech ballistic missiles after five years of imprisonment and probable experimentation may be enough to fatally wound her, but only maybe and even then, it takes a long time for it to be fatal.
- It's Personal:
- She rightly blames Nemesis for an event at the Red Canyon that took everything she loved. She hates him so deeply for it that the opening cinematic concludes with her brutally stabbing him to death.
- On the Crimson Flower route, she directs this towards Byleth and Edelgard: seeing both as vile thieves and apostates who have stolen her mother away from her yet again and goes so far as to claim they're the second coming of Nemesis. From her unhinged perspective, she has every reason to believe this is true.
- Jesus Was Crazy: More like "Saint Peter Was Crazy." Her intentions were largely good (to maintain the legacy of her species and to prevent war from destroying Fódlan as it had in the past) and the church accomplished many great things, but suffice to say, as an emotionally traumatized divine dragon, Seiros was not necessarily the ideal being to oversee Fódlan's development. In routes where she survives, she even chooses to give up some (Silver Snow) or all (Azure Moon) of her authority to Byleth, believing herself no longer worthy of wielding so much influence. On the Crimson Flower route, her insanity is brought much more into the forefront and the player sees how far she is willing to go to defeat her enemies.
- Light Is Not Good: Her skills as The Immaculate One reveal she's a Divine Dragon, making her the first full-fledged villainous Divine Dragon who is insane, but not suffering from dragon degeneration (except maybe on Silver Snow). That said, her "villain" side doesn't come into existence in anything except the Crimson Flower route. Understandable in this case since the Crimson Flower route is the only one where who she believed was her mother's incarnation turns on her/she is directly confronted by the protagonist.
- Love Redeems: Perhaps one of the few Fire Emblem final bosses who can survive at the end of the Silver Snow route if the player S-Supports her.
- Mommy Issues: She's obsessed with her mother Sothis. When she's denied being reunited with her mother due to Byleth not fulfilling their intended role as Sothis's vessel, she ends up going on a rampage. Rhea implies this desire was fueled by her loneliness and isolation being left alone after the Red Canyon incident, and her difficulty in forming trusting relationships with even her remaining kin afterwards.
- One-Woman Army: Tears through Imperial Army formations with trivial ease as The Immaculate One right before the timeskip.
- Our Dragons Are Different: Despite her association with the divine and light magic, Seiros is a sky dragon.
- Psychopathic Womanchild: What she can be when broken or betrayed; a moody, immature psychopath who can't handle being separated from her mother.
- Rage Breaking Point: She was already dangerously unstable to begin with, but when Byleth rejects her at the Holy Tomb on the Crimson Flower route, she completely snaps, and becomes a bloodthirsty Screaming Warrior utterly obsessed with reclaiming Sothis' heart in the name of her mother and other slain kin.
- Recurring Element: Seiros is effectively the traditional Medeus with her Arch-Enemy Nemesis. She is a being far above mortals who, due to her fracturing mental state, runs the risk of eventually losing control and going on a rampage, and on the Crimson Flower route, becomes more in line with the archetype upon going insane and only caring for her own mad wants and willing to destroy anyone who crosses her.
- Semi-Divine: She's the goddess' last daughter and creation.
- Walking Spoiler: It's really hard to talk about her without revealing her true parentage, or that she's the true identity of Rhea.
- Yandere: At her worst. Her obsession with her mother makes her murderous and petty in the Crimson Flower route, where she loses her grip on her vengeful side. This is foreshadowed as early as the opening cinematic when she cradles the bloody Sword of the Creator (which was made from Sothis' body) after killing Nemesis and muttering to her mother that she's avenged her.
- You Gotta Have Blue Hair: She has light-green hair.
Class: Dark Knight (Blaiddyd), Bow Knight (Riegan), Gremory (Lamine), War Master (Goneril), Mortal Savant (Charon), Falcon Knight (Fraldarius), Bishop (Gloucester), Wyvern Lord (Dominic), Great Knight (Gautier), Holy Knight (Daphnel)Blessed by the Goddess with the Crests and Heroes' Relics, the Ten Elites assisted Seiros in defeating Nemesis, King of Liberation. After the War of Heroes, they became heroes of Fódlan and the founders of many of the noble bloodlines in the land. Their descendants bear their Crests, which grant them significant power.
The Ten Elites were Blaiddyd, Riegan, Lamine, Goneril, Charon, Fraldarius, Gloucester, Dominic, Gautier, and Daphnel.
- Ancestral Weapon: The Crests and the Heroes' Relics are passed down from generation to generation in their noble bloodlines.
- Back from the Dead: On the Verdant Wind route, "those who slither in the dark" resurrect ten warriors who call themselves the original Ten Elites. Though Claude is skeptical, the fact they were able to resurrect Nemesis make it possible that they are the real deal.
- Dark Is Evil: They each wield a Dark version of their original weapons, though likely powered by the heart of a different dragon.
- Generation Xerox: Downplayed. Of the ten of them, only three (Lamine/Mercedes, Gautier/Sylvain, and maybe Charon/Catherine) are likely to share classes with their descendants. Goneril and Fraldarius are actually in gender-locked classes that their descendants Hilda and Felix can't access.
- Heroic Lineage: They are a cornerstone of the Church of Seiros and Fódlan's history and their descendants bear their Crests.
- Historical Hero Upgrade: While they're hailed as heroes in the present day, the Ten Elites were allies of Nemesis during the War of Heroes, bandits who helped him slaughter the Children of the Goddess. After Seiros won, she canonized them as heroes to encourage the use of Crests among their descendants. Only the Four Saints are aware of their true nature.
- Long-Lived: Recieving Crests gave them lifespans that spanned centuries. Indeed, the Nemesis war alone spanned nearly a hundred years.
- One Extra Member: They originally had another member, Maurice, who was stricken from history after he was transformed into the Wandering Beast, though enough knowledge remained via rumors for his descendants to suffer mistreatment for bearing his Crest. Indeed, Marianne gets accused by a scholar of being the Wandering Beast.
- Posthumous Character: Though long dead, the Ten Elites continue to influence the land of Fódlan. Averted on the Verdant Wind route, where "those who slither in the dark" resurrect them.
- Precursor Heroes: They defeated Nemesis in Fódlan's distant past, and are hailed as legendary heroes in the present day. In truth, they were bandits who fought alongside Nemesis, but were rewritten as heroes in the present day.
- Recurring Element:
- The Ten Elites, along with the Four Saints, are one of the Twelve Crusaders of Jugdral, a group of heroes blessed by godlike entities with powers beyond those of ordinary people who fought a corrupt evil, and were immortalized as religious figures whose bloodlines possess great political and magical power. Unlike the Crusaders, however, the 10 Elites received a Historical Hero Upgrade and forcibly stole the power from the divine entity.
- On the Verdant Wind route, they become the game's equivalent of the Deadlords, being the undead champions of the Big Bad.
- Transhuman: They were blessed with magical powers by the goddess in the distant past, and passed these magical powers down in the form of Crests to their descendants. In truth, they murdered the goddess and magically infused themselves with her blood.
- Two Girls to a Team: Lamine and Fraldarius were the only two female members of the group.
- The eleventh Elite, Maurice, was stricken from the history books after transforming into a Demonic Beast. His Crest, passed down through House Edmund, is said to bring misfortune to those who bear it.
- There are several Crests whose originators were lost to history, their original bearers are implied to have undergone the same fate as Maurice.
- Wolfpack Boss: On the Verdant Wind route, they are all fought together as the last line of defense between you and Nemesis himself.
The Four Saints were Cethleann, Cichol, Indech, and Macuil.
- Faking the Dead: All four of them fake their own deaths, with Indech & Macuil taking the forms of dragons, while Cichol & Cethleann take on the new identities of Seteth & Flayn.
- The Four Gods:
- Seiros is the Yellow Dragon, Indech is the Black Turtle, and Macuil is the Vermilion Phoenix (well, he's a griffin, but he otherwise fits). We don't see Cichol or Cethleann's dragon forms, but based on the symbolism we do get, it is most likely that Cichol is the White Tiger and Cethleann the Azure Dragon.
- Their elemental affinity, much like the season theme of each route, is Played With. Cichol is an earth dragon, an element commonly used to replace metal for the White Tiger, Cethleann is a light dragon, something that could loosely be connected to fire due to giving warmth, and Macuil is attuned to wind, an element commonly used to replace wood due to its association with windy weather. The latter two even have their elements flipped, as the Azure Dragon is the one associated with Wood/Wind, while the Vermillion Phoenix, like its color suggests, is related to fire.
- Heroic Lineage: They are a cornerstone of the Church of Seiros and Fódlan's history and their descendants bear their Crests. Judging by Flayn's B support with Linhardt, where she insists that Cethleann never married and implies she's never had children, along with the fact that she is Cethleann and the Saints have been secluding themselves from humanity for a millenia, it's entirely possible that none of their successive Crest bearers are their blood descendants. As we learn later, Nabateans can safely (and seemingly easily) give their blood to humans and thus give them a Crest, with said Crest continuing on in that family's bloodline indefinitely.
- Humans Are Bastards: After having their mother and family killed by ambitious humans and witnessing Fódlan's violent history, and for the longest time secluded themselves from society. Macuil in particular carries the most disdain, despising Claude and Byleth for being the descendants of the Ten Elites (in Byleth's case, he seems to mistake their connection to Sothis as being a descendant of Nemesis). Indech is neutral, secluding himself from the world and killing those who fight him for his weapon, but he respects warriors who have the strength and skill to challenge him, and doesn't dislike people so much as having issues interacting with them. While Cichol and Cethleann are more positive towards humanity, they are aware that their nature makes it almost impossible to co-exist with them and they go through periods of assuming false identities before disappearing or going into hiding.
- It Is Pronounced "Tro-PAY": Cethleann is pronounced Sethleen in this game, rather than the correct Ke'len; this is puzzling, considering Cichol's name is pronounced correctly.
- Light Is Good: Cethleann's Crest is associated with light, and she's remembered as a compassionate healer.
- Odd Name Out: Macuil's name comes from Aztec mythology, while the other three are named after Fomorians.
- Our Dragons Are Different: In official history, the Four Saints and Seiros were merely long-lived humans like the Ten Elites. However, in truth, they and Seiros are the sole known surviving children of the divine dragon Sothis, with lifespans a good deal longer than even humans granted their blood.
- Precursor Heroes: Assisted the 10 Elites and Seiros in putting down Fallen Hero Nemesis in the distant past, and are lauded for it in the present day. Unlike the 10 Elites, allies of Nemesis, the Four Saints in truth were firmly on Seiros' side, being survivors of Nemesis and the Elites' massacre of Zanado's population.
- Posthumous Character: Said to have died a long time ago. Averted; they are all very much alive.
- The Smart Guy: Macuil was Seiros' chief tactician and a pioneer of the magical arts.
- The Smurfette Principle: Cethleann is the only female of the Four Saints and along with Seiros the only known female hero of the War of Heroes.
- Socially Awkward Hero: According to Seteth, Indech tended to isolate himself because he didn't know how to connect with people.
- Sole Survivor: They along with Seiros are the only survivors of their kind known. If Seteth, Flayn, and Rhea (being Seiros herself) die, Indech and Macuil will be the last of the Nabatea (at least in Fódlan).
- Transhuman: Alongside the 10 Elites, they were blessed by the goddess in the distant past, and passed these magical powers down in the form of Crests to their descendants. Averted in truth, as the Four Saints were not humans, but Nabateans who were created by the goddess and willingly given her powers, unlike the human Elites who took her power by force.
- World's Strongest Man: Indech was said to have felled many warriors across many battlefields. Cichol's Crest is also associated with strength and his Relic is one of the strongest weapons in the game.

- Chest Insignia: Has the Crest of Ernest, a "lost crest" on her clothing.
- Curtains Match The Windows: Her red eyes match her hair.
- Demoted to Extra: Unlike in Awakening and Fates (albeit as DLC for the latter), Anna is returned to being a simple merchant. She does have some prominence in a few supports. She will, however, become a playable character via DLC once again in Wave 3.
- Downloadable Content: She's scheduled to become playable in DLC wave 3.
- Memetic Hand Gesture: Wouldn't be an Anna without her finger on her cheek.
- Money Fetish: As usual, Anna's obsessed with money and charges her wares with rather high prices, something that is lampshaded by Petra early in her Support with Ashe. Unfortunately for Anna, the latter happens to be an excellent haggler and has her give them a 20% discount.
- New Job as the Plot Demands: She works as everything from a apothecary, a bookseller, to even a bartender given how she shows up in multiple supports.
- Promoted to Playable: According to Famitsu, she is to be made playable as paid DLC in wave 3.
- Secret Shop: She runs one outside the monastery, and the player can buy her wares before they engage in a skirmish, though it will only be available in Part 2.
Monica von Ochs
Voiced by: Marika Kono (Japanese), Colleen O'Shaughnessey (English)
A red-haired student attending the academy.
- Disappeared Dad: A guide to the Empire nobility in the library notes that Monica's father was killed during the war with Brigid and Dagda.
- Foreshadowing: After her rescue, Monica can often be found spending a great deal of time in Edelgard's company. The reveal that she's actually Kronya, a member of "those who slither in the dark," is a big hint towards Edelgard working with them.
- Kill and Replace: Implied to have been the victim of this, like Tomas was. It's noted that her personality before disappearing the year before was different.
- Non-Standard Character Design: Her portrait is angled and colored differently compared to the other characters, foreshadowing she's not who she claims to be.
- Wolf in Sheep's Clothing: Kronya takes her identity in order to infiltrate the Officers Academy.
Class: Wyvern Lord
Voiced by: Ryo Sugisaki (Japanese), Brad Venable (English)
A warrior general of Almyra who despite his jovial nature has no issues leading his people in raids against Fódlan. Was a teacher to Claude in the past.
- An Axe to Grind: His main weapon.
- Big Damn Heroes:
- On the Verdant Wind route, he joins forces with the Alliance to attack the Empire.
- He tries to do this on the Crimson Flower route to support Claude against the Black Eagle Strike Force, but his forces and himself are overpowered.
- Big Fun: He has a gut, but he's very jovial even to his enemies.
- Boisterous Bruiser: He goes into battle with laughter and a smile.
- Dragon Rider: His class is Wyvern Lord, and when he appears as a boss he's always accompanied by ever-spawning numbers of wyvern riders.
- Improbable Aiming Skills: As Alliance forces infiltrate Fort Merceus, Nader enters with forces of his own. He and Claude meet in a test of skill and draw their bows toward each other, and the arrows collide mid-air.
- Out of Focus: Unlike many other significant NPCs, he doesn't appear at all on the Azure Moon or Silver Snow routes.
- Red Baron:
- He is referred to as "The Undefeatable." However, Judith snarks about how the name came from him running away from battle before he could be defeated.
- On the Crimson Flower route, after the fall of the Leicester Alliance, facing him in an unlockable paralogue with Edelgard will have the two amusingly comment they'll have to call him "The Once Defeated" after his defeat at Derdriu now and that it doesn't have the same ring to it.
- Sue Donym: He poses as a retainer named Nardel whenever Claude needs him to do a favor within Fódlan.
Voiced by: Tasuku Kida (Japanese), Joe J. Thomas (English)
A bandit leader that takes refuge in the ruins of Garreg Mach monastery during the time skip.
- Alas, Poor Villain: After he's killed, Seteth remarks that Pallardó used to work in Garreg Mach, but after the monastery's defeat to the Empire, he was among the people who fell on hard times and turned to banditry to get by.
- Dirty Coward: He tries to flee the battlefield after he's defeated for the first time, and has to be defeated again before he can escape.
- Lone Wolf Boss: He's the first boss of the second part of the game in three routes out of four, but he has no ties with any of the major factions battling each other.
- Starter Villain: He's the first enemy fought during Part II for all routes save Crimson Flower, as on that route Garreg Mach has become a base of operations for the Empire.
Voiced by: Kyle McCarley (English)
The unnamed watchman who guards the monastery's main gates. He will often discuss the current goings-on with Byleth.
- Catchphrase: "Nothing to report! Except..." Always followed by a discussion of the current events.
- Manly Tears: He can barely hold himself together talking to Byleth after Jeralt's death.
- Nice Guy: He's never anything but cheerful and polite in his conversations.
- No Name Given: Despite being a recurring character, he's only ever called Gatekeeper.
- Strong Family Resemblance: He has a brother who looks and sounds just like him, but lacks his loyalty to the Church.
- Subverted Catchphrase: In Chapter 6, when Flayn is abducted, he drops his usual greeting in favor of "Greetings, Professor! Today...there is quite a bit to report!"
- Undying Loyalty: He will always side with the Church, and if the player sides with Edelgard, he is replaced with his brother.
The Wind Caller
A massive avian dragon who wields the Crest Stone of Macuil.
- Actually, I Am Him: He's THE Macuil of the Four Saints.
- The Aloner: Prefers living isolated from society, even losing track of how long he's been alone over the ages.
- Blow You Away: Has innate power over wind as a wind dragon.
- Bonus Boss: Only faced in a secret Paralogue during the Verdant Wind route.
- Cool Uncle: He has a soft spot for his niece Cethleann, a.k.a. Flayn.
- Our Dragons Are Different: He's a large feathery bird that is also a dragon.
- Humans Are the Real Monsters: He doesn't have a particularly good view of humanity. Even when Seteth asks for his aid in rescuing Rhea, he rebukes him, detesting human civilization in general and wanting nothing to do with even his fellow Children of the Goddess. That said, he does warn your regular units to leave rather than simply fight to kill from the start.Wind Caller: You have had your fun. If you are going to flee, now is your chance. If you are not going to flee... I shall take your life as payment!
- Morality Pet: He's much nicer to Flayn in their conversation than he is with Seteth, Byleth, or Claude.
- Roc Birds: Is as big as The Immovable or The Immaculate One, which means he's even bigger than a house.
- Semi-Divine: Being one of the Children of the Goddess, The Wind Caller is this by default. Flayn calls him 'uncle'.
- Spanner in the Works: Seteth and Flayn have been keeping their identities as Cichol and Cethleann a secret, and if Flayn interacts with The Wind Caller during battle, he unknowingly (nearly) spoils it by speaking fondly to her and addressing her as "Ceth-", causing Flayn to hurriedly interrupt and ask him to keep quiet.
- Sleepyhead: The battle against him ends when he decides to, of all things, fall asleep during the battle.
A massive black turtle dragon who wields the Crest Stone of Indech.
- Actually, I Am Him: The guardian of Indech's legendary bow is Indech himself. Doesn't help he's bad at hiding it and even says the bow was his own when defeated.
- Blood Knight: He enjoys a good fight and is more than willing to reward those who best him in combat.
- Bonus Boss: He appears in a Secret Paralogue only if Leonie and Linhardt are recruited into the same house. On the Crimson Flower route, he's also only accessible as long as you don't kill Seteth and Flayn in Chapter 15.
- Dented Iron: Whether it be from old injuries or simply age is unclear, but if he speaks with Seteth (who notes the turtle dragon is holding back in the fight), he admits his power is not what it used to be and the best he can do is "have fun meddling with humans who wander in here". As such, it's decided it'd be best for him not to help with the search for Rhea, as it might be too much for him.
- Humans Are the Real Monsters: Averted. Unlike the Wind Caller, The Immovable carries no grudge against humans and indeed admits he enjoys testing and rewarding them. He gives those who find him chances to run and lets them come to him if they wish to fight (though his phantom soldiers and he himself will not hesitate to strike down those who do), and upon being defeated, he gives up Indech's weapon without complaint. However, given that his Paralogue becomes inaccessible if Seteth and Flayn (his brother and niece, respectively) die during Chapter 15 of Crimson Flower regardless if Leonie is recruited, he may hold a grudge against humans who have killed both his fellow Saints and last remaining family.
- Just Toying with Them: Linhardt notes that The Immovable's movements during the fight are not those of someone fighting seriously. The Immovable acknowledges this, but as he said at the beginning of the fight, this is a test, not a true battle.
- Making a Splash: He is a water dragon and uses water-based attacks.
- Our Dragons Are Different: He's a turtle dragon!
- Semi-Divine: He is one of the Children of the Goddess. And, like The Wind Caller, Flayn calls him 'uncle'.
- Socially Awkward Hero: He shows himself as being incredibly friendly when fighting the heroes, even enjoying just how much enthusiasm Leonie has about facing him while declaring she has no crest, but actual social interaction is incredibly difficult for Indech, and so he retreated away from the world.
- Spanner in the Works: Seteth and Flayn have been keeping their identities as Cichol and Cethleann a secret, and if Flayn interacts with The Immovable during battle, he unknowingly (nearly) spoils it by speaking fondly to her and addressing her as "Ceth-", causing Flayn to hurriedly interrupt and ask him to keep quiet.
- Threshold Guardian: He acknowledges that he is mostly there to provide a challenge for heroes to acquire a special weapon.
- Turtle Power: He's a massive turtle with a spiky shell.
- Worthy Opponent: When he believes Byleth is Sothis' incarnation, he wants to face them and see such power for himself. He also acknowledges Leonie as worthy of Indech's bow upon being defeated.
A sentient Divine Beast that has terrorized the forests south of Garreg Mach for many years.
- Actually, I Am Him: He is Maurice, the progenitor of the Crest that Marianne bears.
- Bonus Boss: Only faced in Marianne's Paralogue.
- Death Seeker: Not immediately obvious due to his love of killing and eating, but Maurice secretly wants to die. Seeing the Sword of the Creator is enough for him to get his hopes up and pray that Byleth could finally kill him in battle.
- Dying as Yourself: He regains his lucidity in his final moments, and congratulates Marianne for killing him.
- Fog of War: His paralogue features this, which conceals the fact that several demonic beasts lurk around the map.
- Graceful Loser: He congratulates Marianne and her retinue in defeating him, also thanking them for freeing him from his unenviable state.
- Horror Hunger: Having retained his sentience, Maurice has been left a monster hungry for flesh and blood with a heavy amount of Bloodlust to keep him from trying to fight it.
- Laser-Guided Karma: His current state is a result of participating in the murder of Sothis and the genocide of the Nabateans, since his sword made of their bodies is what caused him to transform into a monster. It's hard to say he didn't deserve it.
- Mercy Kill: Your goal during the fight with him is to put him out of his misery.
- Take Up My Sword: Upon his death, he bequeaths to Marianne his Hero Relic Blutgang, trusting that she will be able to wield it better.
- Unperson: Maurice originally fought alongside the other legendary heroes of yore, but turned into a Divine Beast during a battle, leading to his name purged from most records and his descendants treated with scorn (if not outright executed).
The Flame Emperor
Class: Flame Emperor
- "We will cross paths again. I am the Flame Emperor... It is I who will reforge the world."
A mysterious masked figure whose identity is unknown. The Flame Emperor works in the shadows with an ill will towards the Church of Seiros, and was in fact behind the brigand attack on the Officers Academy students at the game's beginning.
- Ambiguous Gender: Their full-body armor, helmet, and mask conceal their gender, but everyone wrongly assumes they are male.
- An Axe to Grind: Wields an axe in their released artwork. It's suspiciously similar to the Victorious Axe Edelgard wields in Heroes.
- Climax Boss: The boss battle with the Flame Emperor serves as the climax of Part One in all routes. The reveal of the Flame Emperors true identity and the subsequent fallout sparks the Wham Episode and represents the point after which the routes all greatly diverge.
- Compressed Hair: After the reveal, you have to wonder how Edelgard manages to fit all of their hair into that helmet.
- Cool Mask: Wears a white and red mask and a helmet to conceal their identity and distort their voice.
- Disc-One Final Boss: They are the main antagonist for the first half of the game, but...
- On the Crimson Flower route, you (re)join her in her crusade against the Church of Seiros.
- On the Azure Moon route, this is averted, and she holds on to the title of Big Bad for the rest of the game in her true identity.
- On the Verdant Wind and Silver Snow routes, while she remains The Heavy for most of the game, she is ultimately outlasted by "those who slither in the dark", who become the true antagonists of the story.
- Dramatic Unmask: On the Azure Moon and Verdant Wind routes, which reveals the Flame Emperor is Edelgard. Averted on the Crimson Flower and Silver Snow routes, where Edelgard reveals from the start of the climactic battle that she is the Flame Emperor and forgoes the helmet completely in the resulting fight.
- Even Evil Has Standards: Despite opposing the church, the Flame Emperor does not approve of what those who slither in the dark do to achieve their goals. They state firmly that they never would have allowed the group to massacre and transform the inhabitants of Remire Village had they known the exact details, though this does little to dissuade a furious Jeralt and Byleth.
- Foreshadowing: Their true identity as Edelgard is hinted at in several ways:
- The Flame Emperors color scheme is primarily black and red, just like Edelgard's.
- They use axes as their primary weapon, which is Edelgard's strongest weapon proficiency. In addition, the axe in the Flame Emperor's artwork is the exact same axe that Edelgard wields in Heroes.
- Theyre called the Flame Emperor, the selfsame title Edelgard is supposed to inherit. Edelgard's C+ support also reveals she has the Crest of Flames.
- During the monthly battle in Chapter 6 on the Crimson Flower route, where the Flame Emperor first confronts you directly, Edelgard is listed as "unavailable." This one is a bit obfuscated by the fact that Dimitri and Claude are also unavailable during their versions of the same chapter for perfectly innocent reasons.
- Should Edelgard confront the Death Knight in Chapter 8 or Kronya and/or Solon in Chapter 10, they express surprise that they're attacking them like this wasn't at all a part of some plan. Similarly, the Death Knight is particularly bemused if Edelgard is made to fight him in Chapter 4.
- On the Crimson Flower route, after the Chapter 8 battle, Edelgard has a very suspicious conversation with you where she not-so-subtly hints that one day you might figure out the Flame Emperor's objectives and be able to look them in their unmasked face to decide whether or not you'll follow them. She doesn't even react negatively if you suggest you might be interested in teaming up with the Flame Emperor (though she does note it would be smart not to trust someone whose face you don't even know).
- On the Azure Moon route, the Flame Emperor leaves a dagger behind after she is caught talking with Kronya and Solon, right after Dimitri tells Byleth that he gave Edelgard a gift of a dagger when they were children. Dimitri visibly panics at the sight of this dagger, damning her further. As a final nail in the coffin, eagle-eyed players will notice that this dagger is the same one Edelgard used in the prologue to defend herself from Kostas.
- On the Azure Moon and Verdant Wind routes, the Flame Emperor is in command of Adrestian soldiers when they fight you in Chapter 11. In addition, the Flame Emperor has Charm (typically associated with Lord characters) and Seal Strength and Seal Magic (which Edelgard was packing as a boss in Chapter 7) in their skill pool.
- Despite having a filter on their voice, the Flame Emperor's voice still has a distinctly feminine inflection and pitch to it, similar to how the Death Knight has a very clearly masculine voice behind the filter.
- Identity Concealment Disposal: After their identity is revealed, they dump the helmet and mask for the ensuing boss fight (or fights, on the Silver Snow route). On the Azure Moon route, the mask is physically destroyed after the reveal.
- Malevolent Masked Men: They conduct terrorist operations against the Church of Seiros while hiding their face and identity behind a mask.
- Red and Black and Evil All Over: With the exception of their mask which is partially white, the Flame Emperor's attire is black and red, and they're one of the game's main antagonists.
- Red Herring: Regardless of which house you choose to lead, the game leads you to believe that your chosen lord is the Flame Emperor. None of your lords are present whenever the Flame Emperor appears, such as in Chapter 6 and Chapter 8, the former more so due to the house leader being listed as unavailable for that battle. In Chapter 8, when the Flame Emperor talks with Byleth and Jeralt, Hubert, Dedue or Hilda conveniently appears, allowing the Flame Emperor to vanish when Byleth and Jeralt's attention is drawn away. In addition, Edelgard hints that she knows more than is strictly sensible about the Flame Emperor's motivations, Dimitri makes it quite clear that hes out for revenge against certain people who may be affiliated with the Church, and Claude shows a fixation on Byleth and the Sword of the Creator after the Flame Emperor states that they need more information about both. In addition, each of your lords is friendly with, and spends a lot of time with, someone who turns out to be evil and working with the Flame Emperor: namely, Edelgard and Monica, Dimitri and Lord Arundel, and Claude and Tomas. Towards the end of Part One, each of the Lords have a moment that settles their innocence. For Dimitri, he eavesdrops on a conversation with the Flame Emperor and "Those Who Slither In The Dark" in Chapter 10. For Claude, he is present when the Flame Emperor attacks the Holy Tomb in Chapter 11. For Edelgard, she flat out admits it was her in Chapter 11 and spends the rest of the fight unmasked.
- Samus Is a Girl: Is actually Edelgard in disguise.
- Secret Identity: When not conspiring against the Church of Seiros, they live a double life as Edelgard von Hresvelg, princess of Adrestia.
- Villain Teleportation: Makes use of this to escape whenever they confront Byleth, and they also make their entrance in Chapter 6 this way.
- Walking Spoiler: The reveal of the identity of the Flame Emperor has major ramifications on the games story and sets the stage for the majority of the rest of the game.
- We Can Rule Together: They try to convince Byleth to join them a couple of times, though by the battle in the Holy Tomb, they seem to resign themselves to the idea that Byleth most likely won't. On the Crimson Flower route, you take her up on her offer, to her surprise and gratefulness.
Class: Death Knight
- "One of us will die, the other will live. I will enjoy this dance of damnation."
A grim reaper-themed knight who is rumored to prowl the streets of Garreg Mach at night, attacking people and abducting them. Their appearance invokes an otherworldly origin.
- Achilles' Heel: As dangerous as he is, he is a mounted unit that still has a fatal weakness to anti-cavalry weapons, most notoriously the Dark Spikes spell, which Lysithea can learn early enough to have by the first encounter with him.
- Alas, Poor Villain: On the Azure Moon route, if Mercedes and Casper's paralogue was completed before the final battle against him, when he dies, Mercedes cradles him, tearfully apologizing for being a lousy older sister.
- Ambiguous Gender: Their full-body armor, helmet, and mask conceal their gender, but everyone correctly assumes they are male.
- Blood Knight: They refer to their conflict with the heroes as a game, and the Flame Emperor tells them they'll have "more opportunities to play soon".
- Bonus Boss: The first four times (or three, if you jump ship to work with his boss) you encounter him, he's far, far stronger than your units can reasonably hope to defeat. He's not invincible, though, and beating him nets you a rare Dark Seal.
- Cain and Abel: Acts as the Cain to his half-sister Mercedes's Abel. ...Unless you poach Mercedes to the Black Eagles and stick with the Adrestians.
- Card-Carrying Villain: In his summoning quote in Heroes, he calls his own deeds "ghastly".
- The Dragon: Serves this role for the Flame Emperor, being their most powerful servant. However, by the time Part II rolls around, he's settled into the role of The Brute and either Hubert or Byleth becomes their unquestioned second-in-command (assuming the first one didn't outrank him to begin with and the second one defects to their side).
- Even Evil Has Loved Ones: Despite being a brutal villain, he still cares for his elder half-sister Mercedes, and tries to convince her to go somewhere safe in her Paralogue so he doesn't have to kill her, but instead has to settle for giving her the Relic.
- The Grim Reaper: Part of their motif. Their Japanese name is quite literally the Grim Reaper Knight.
- Guest-Star Party Member: Due to Edelgard being the Flame Emperor, he becomes an ally unit in Chapter 12 of the Crimson Flower route.
- Hypercompetent Sidekick: At least on the battlefield. He's an obscenely powerful Lightning Bruiser who is generally far stronger than your party can reasonably expect to defeat until the very end of the game; his boss the Flame Emperor is fairly slow and gets ripped up by most mages and anti-armor weaponry, and The Reveal of their true identity indicates that they start off as a poopy level 1 Noble that the Death Knight could flick off like a booger.
- Jack-of-All-Trades: While he primarily specializes in lances and riding, with the exception of faith magic he's got a little experience with everything.
- Karma Houdini: On the Crimson Flower route, he completely evades punishment for aiding and abetting Flayn's kidnapping and the Remire massacre due to becoming Byleth's ally after their Hazy Feel Turn. He also downplays this in regards to shanking Manuela; she mentions he sincerely apologized offscreen, and her comments indicate that the matter is pretty much settled.
- Kick the Dog: In his combat dialogue with Flayn, he mocks her for having been kidnapped and having her blood stolen in Chapter 6, which is something Flayn admits she has trauma over years after the fact.
- Malevolent Masked Men: He's a horrifying villain who helps villainous schemes and enjoys nothing more than combat, and he hides his face behind a mask and helmet shaped like a skull.
- Names to Run Away from Really Fast: Whether Grim Reaper Knight in Japanese or Death Knight in English, their name isn't exactly comforting. This even applies to his weapon, as Sariel is one of the archangels of death.
- The Only One Allowed to Defeat You: His attitude towards Mercedes and arguably the closest he has to a personal goal in general. That being said, he seems to be picky about the circumstances over when and how it should happen; if Mercedes engages in combat with him in his final encounter with her Paralogue completed, the Death Knight will ask her to leave, for the location the heroes are laying siege to should not be her place of death.
- O.O.C. Is Serious Business:
- When interacting with most characters, the Death Knight is either raring for battle, amused, or uninterested, depending on the character. Interactions with Mercedes are the exception, as early as the first encounter with him, where if Mercedes engages in combat with the Death Knight, he will ask in bewilderment if the encounter was preordained. This continues in a Paralogue involving Mercedes, where he is uncharacteristically nice to her (while also remaining somewhat vile, to the shock of everyone else present), leading to the Pet the Dog moment described below. A Justified Trope since he is her long lost brother.
- When fought at Fort Merceus on the Verdant Wind and Silver Snow routes, he books it once your army gets close to him, and the map's objective changes to preventing his escape which seems oddly out-of-character for a Blood Knight like him. At the chapter's end, this makes sense: he knew "those who slither in the dark" were about to obliterate the fort with "javelins of light" and obviously wanted to be as far away from that as possible, and also to goad his Worthy Opponent Byleth into following so they wouldn't die in the blast.
- Orcus on His Throne: Despite the fact that he could very easily destroy Byleth and their students in early encounters if he was proactive in attacking them, he seems content to simply sit there and watch unless you deliberately provoke him. He will only start moving in later encounters once the team is more capable of taking him on, though he's still not to be taken lightly. On Maddening Mode, however, he's a lot more proactive as early as his first appearance.
- Pet the Dog:
- He gives a sincere apology to Manuela for stabbing her before he departs to the front lines on the Crimson Flower route.
- He gives Mercedes their family's Relic in their paralogue, though not without saying he won't hesitate to kill her if they meet again.
- In Caspar and Mercedes' paralogue, should Caspar best him in combat, he likewise bestows the Scythe of Sariel to him, likely with a Worthy Opponent justification.
- Promoted to Playable: He makes his playable debut in Fire Emblem Heroes.
- Put on a Bus: After the timeskip on the Crimson Flower route, he is only mentioned in passing once or twice and spends the second half of the game fighting on another front.
- Recurring Boss: He is currently tied for the record for most appearances in one game as an enemy, with 6; you fight him in chapters 4, 6, 8, 12, 18, and 19 on the Verdant Wind route. If you count paralogues, the count goes up to 7, as you also fight him in Mercedes and Caspar's paralogue.
- Recurring Element: The Death Knight is essentially Three Houses' version of the Black Knight. They're both powerful opponents who must be avoided rather than fought as they can cut down your units with ease, they both develop a fixation on the child of a legendary mercenary as a worthy opponent, and they're both protectors to a white-haired female lord. Oh, and the name of their personal class is also identical to their name as a unit.
- Redemption Demotion: Downplayed. He's still undeniably powerful as a green NPC ally in chapter 12, provided you chose the Black Eagles and sided with Edelgard, who can take on nearly any opponent on the map save maybe the Golem enemies on his lonesome (even the stage boss Rhea will find herself on the losing end of their clashes), but he has an unfortunate tendency to go Leeroy Jenkins and get splattered into the ground by Catherine.
- Shaped Like Itself: He has a unique version of the Dark Knight class, called the Death Knight class.
- Sinister Scythe: Wields one called the Scythe of Sariel (classified as a lance for gameplay purposes).
- Spanner in the Works: During the battle to claim Fort Merceus on the Verdant Wind and the Silver Snow route, he starts fleeing the fort and points to the missiles launched by "those who slither in the dark," giving the Church and Alliance time to escape its destruction. All to keep his Worthy Opponent Byleth from dying and giving the heroes the chance to eventually defeat the empire and their allies.
- Villain Forgot to Level Grind: Averted. He actually does get stronger every time you encounter him, it's just the students will eventually start growing faster than he does.
- Villain Teleportation: Makes use of this to escape in his first three appearances.
- Worthy Opponent:
- Initially subverted with Byleth. The first time the Death Knight encounters them, they think of the professor as a mere weakling. It's only after Byleth obtains the Sword of the Creator that the Death Knight comes to consider them a worthy foe, and becomes rather annoyed when the Flame Emperor prevents them from fighting Byleth during the events of Chapter 6.
- Its implied during Mercedes and Caspars paralogue that he sees the latter as a worthy opponent, but only if Caspar actually manages to best him in combat. If the latter condition is fulfilled (both since the Death Knight is a tough opponent and the mission objective specifically says the mission can be finished without routing him), the following cutscene adds an extra bit after the Death Knight hands Mercedes a Relic where he simply hands Caspar the Scythe of Sariel, declaring that Mercedes should be safe until the Death Knight can kill her.

- An Axe to Grind: As is tradition for Fire Emblem brigands.
- Ironic Echo: Shouts, "You'll die!" before he nearly kills Byleth and Edelgard at the end of the prologue. When the job he received from the Flame Emperor goes awry and he demands to know what's going to happen to him now, the Emperor simply replies, "You die." This is foreshadowing that Edelgard in the Flame Emperor.
- Irony: Almost kills Edelgard at the end of the prologue, never mind the fact that she is the one who hired him to attack the students in the first place.
- Small Role, Big Impact: It's his attack on the students of Garreg Mach that leads to Byleth getting noticed by the Officers Academy, thus kickstarting the entire plot.
- Starter Villain: Just like in most Fire Emblem games, a bandit serves as the first villain you encounter. That said, he survives a little longer than your average prologue bandit boss, as he's also the boss of Chapter 2's mission.
- Warm-Up Boss: He's the first boss of the game, and he's fairly easy compared to what's to come.
- You Have Failed Me: The Flame Emperor leaves him out to hang at the beginning of the game after he fails to assassinate the lords. Depending on the route, she can even kill him with her own two hands.
- You Have Outlived Your Usefulness: When Kostas asks the Flame Emperor what are they going to do, given the botched attack in the prologue, the Emperor's response is a laconic "You die," before teleporting out, leaving Kostas out to dry.
Voiced by: Takahiro Miwa (Japanese), Todd Haberkorn (English)
- Just Following Orders: When he's defeated, he tries to desperately play this card as he dies.
- Smug Snake: Talks a big game when he gets into a fight and boasts about his intent to kill, but once defeated he begs for mercy and tries to claim he was Just Following Orders.
- We Hardly Knew Ye: He's only introduced immediately prior to the battle in the Holy Tomb, and most likely ends up dead by the end of the battle.
- What Happened to the Mouse?: If he is left alive (seeing as you only need to defeat the Flame Emperor to finish the battle), he makes no later appearances whatsoever and is never seen again even on the Crimson Flower route where you side with Edelgard.
"Those Who Slither in the Dark"
- Abusive Precursors: They are the descendants of the technologically advanced civilization of Agartha, who developed a god complex and tried to kill Sothis to conquer Fódlan. This did not go well, but their survivors learned absolutely nothing, instead becoming a bitter cult who pulled the Abusive Precursors gig themselves when they influenced Nemesis into murdering the sleeping Sothis and her children for use of their body parts to create the first Crests and the Hero's Relics.
- Always Chaotic Evil: The Agarthans and descendants we see in the game do not paint a positive picture of their civilisation as a whole, to put it lightly.
- Big Bad: Aside from the two countries you stand at odds with, these guys stand on equal footing with the Greater-Scope Villain. They are the main final enemies on the Verdant Wind route.
- Blood Magic: Their spells and rituals often require blood in some manner, as do many of their experiments.
- Casting a Shadow: They are proficient in dark magic. Since dark magic is associated with science in this game, it's natural darkness and technology would go hand in hand.
- Death from Above: Some of their most powerful magic and weapons are capable of this. The worst is obviously their ICBMs, which they use to destroy the fortress city of Arianrhod on the Crimson Flower route and Fort Merceus on the Verdant Wind and Silver Snow routes.
- Fantastic Racism:
- They consider the people of Fódlan to all be savages at best, or indeed no more than simple animals. This is motivated in part by their advanced technology giving them a extreme sense of superiority, but in general they seem to hate the surface humans simply for being able to live lives they believe they have been denied (Hubert noting they hold great disdain for the people of Fódlan, as well as the Children of the Goddess.
- They despise the Children of the Goddess, to the point of repeatedly trying to wipe them out. However, as Rhea notes, the one they hate the most is Sothis (and by extension Byleth).
- Fatal Flaw: Their hubris and confidence that everyone else is inferior to them. It's exactly what led to the destruction of their precursors in Agartha, and "those who slither in the dark" clearly didn't learn their lesson from that. They don't treat Edelgard, their "ally" who is constantly antagonistic towards them and not hiding too much her intentions to destroy them, too seriously. Which backfires on them in her epilogues where they are destroyed by her, and also is part of the reason they get destroyed in all other routes aside from Azure Moon, and even then they still suffer heavy losses and lose all their leadership.
- Feeling Oppressed by Their Existence: They want to wipe out the Children of the Goddess to set humanity "free". Of the five surviving Children, two completely avoid human contact, one is a stuffy but good-hearted bureaucrat who draws children's books in his spare time and is a reformist within the church system, and one is a kindly teenage girl who's obsessed with fish and thinks swords are better used for cutting fruit than for cutting people. The only one who can be called oppressive in any sense is Rhea/Seiros, who's only like that because of the trauma she went through after they drove her race to near-extinction.
- Hubris: Their precursors, Agartha, grew so technologically advanced they thought themselves gods. They still show signs of it, denouncing everyone outside their cult as a "beast" and proclaiming themselves "saviors."
- Humanity Is Superior: Due to their ancestors' war with the Children of the Goddess, they long to erase the Children and their mother Sothis off the face of the earth to ensure human dominance. Though by "human" they seem to only mean themselves, as they regard the rest of humanity as little more than simple animals to be used, experimented on, or destroyed. To them returning themselves to supreme power over Fódlan is what will make them "saviors".
- Humiliation Conga: By the end of the Azure Moon route, they've lost Edelgard and the Empire, their infiltrators in Faerghus and Garreg Mach, their role in the tragedy of Duscur is revealed by Cornelia, and Thales is killed while still disguised as Arundel, all without Dimitri even becoming aware of the group as a whole. Their plans centuries in the making is completely destroyed by accident.
- Karma Houdini: In two of the routes, they are not confronted directly, but are implied to have diminished significantly as a threat. At the end of the Crimson Flower route, Edelgard proceeds to turn against them after uniting all of Fódlan, though their implied annihilation happens offscreen. On the Azure Moon route, Dimitri never unearths their full conspiracy, but comes to realize that a secret force was behind the Tragedy of Duscur after his confrontation with Cornelia. Additionally, Kingdom forces end up unknowingly killing Thales under his guise as Lord Arundel, which would likely deal a major blow to the leadership of "those who slither in the dark". On the other hand, the Verdant Wind and Silver Snow routes avert this, as Byleth and company are able to find and wipe them all out with a little tip from Hubert.
- Kill and Replace: Dialogue from Kronya and others suggest Monica and Tomas were real people that they murdered to disguise themselves as. It's left ambiguous if this is the case for Arundel as well.
- Let's You and Him Fight: One of their key overarching plans is to manipulate Edelgard and Dimitri into instigating a major continent-wide war against each other with the hope that they would take the Church of Seiros and the vast majority of Fódlan's power structure down with them. This is why they spent the past five or six years doing things like starting the Duscur Massacre, performing Crest experimentation on Edelgard, and then pushing her against the Crests and Rhea. This plan is made most explicit on the Azure Moon route, when members of the group like Cornelia and Arundel/Thales keep urging Dimitri and Edelgard to go "kill each other."
- Mad Scientist: They are dedicated to pushing the boundaries of magic and science, to the point of breaking out of Medieval Stasis in the past, but have absolutely zero moral scruples in how they do so. Putting Remire village under a Hate Plague, performing horrific experiments on Edelgard and Lysithea to empower them with Crests at the cost of drastically reducing their lifespans, manipulating Nemesis into murdering Sothis and her children and making weapons out of her corpse, and these are just the things we know about.
- Names to Run Away from Really Fast: With a name like "those who slither in the dark," you'd think they were some kind of cult or assassin ring. You'd be right, except they're worse.
- Necromancer: They have the ability to ressurrect the dead, and on the Verdant Wind route, they bring back Nemesis and warriors who are ostensibly the Ten Elites.
- Never My Fault: They despise Sothis and the Children of the Goddess partly because Sothis near completely wiped Agartha. Keep in mind, that only happened because they tried to kill Sothis in their hubris.
- Tautological Templar: Ignatz notes that they truly believe themselves to be righteous saviors out to "free humanity", and so they'll commit any act to liberate mankind from the Goddess.
- Technologically Advanced Foe: Despite the world of Three Houses being in a renaissance-esque setting, "those who slither in the dark" have access to weapons from the modern age, such as ICBM missile tech and mechs.
- Theme Naming: All of their names are Greek in origin, and in particular, three of them share names with an equivalent number of the Seven Sages of Greece: Thales, Solon, and Myson.
- Unknown Rival: On the Azure Moon route, as Dimitri and the Blue Lions don't learn who they are, but still deal significant damage to them, having unwittingly killed their leader Thales and thwarted Edelgard, who was a major investment for them.
- Ungrateful Bastard: Sothis and the Nabatea helped them develop advanced technology and shared their knowledge with them. They respond by having repeated wars with nuke-like weapons of mass destruction, against Sothis' teachings, eventually culminating in them turning their weapons on Sothis herself. It didn't end well for them, with Sothis striking back in a war that devastated the land and left most of the humans dead, then fixing the land they ruined. Instead of admitting any fault they blame her and her children for all of it.
Solon and Kronyas leader and an important figure within "those who slither in the dark." In order to carry out his master plan, he acts in the shadows of Fódlan.
- Beard of Evil: He sports a notable goatee and is one of the main antagonists of the game.
- Big Bad: Wavers between this and Greater-Scope Villain depending on the route. As the leader of TWSITD and the one with the closest connection with Edelgard's past, he's directly responsible for Edelgard's ambitions and resources. Stopping Edelgard is stopping his main agent of Fódlan's destruction, and even in the Black Eagle route, Edelgard recognizes he's the threat that must be stopped by unifying Fódlan against the Church.
- Can't Kill You, Still Need You: When he saves Kronya from Byleth after she kills Jeralt, he states it's because she still has another role to play. He later clarifies it was to keep the nature of their bodies a secret, only for Solon to later reveal that "role" involves being a Human Sacrifice for Solon's spell to deal with Byleth in the very next chapter.
- Climax Boss: Fought right before the final bosses Nemesis and Seiros on the Verdant Wind and Silver Snow, respectively.
- Curtains Match the Window: His white hair and beard match his Prophet Eyes.
- Evil Counterpart: To Post-timeskip Dimitri. Both leaders of their respective groups dedicate themselves to avenging the deaths of their people. They're willing to sacrifice themselves and their allies ruthlessly pursuing their enemies (The Church, Rhea, and Children of the Goddess for Thales, and Edelgard for Dimitri). They differ, however, in that Dimitri was personally affected by the truly senseless Tragedy of Duscur, while Thales obsesses over a "crime" that happened to his long dead ancestors, who deserved their own destruction. Additionally, Dimitri mourns the deaths of his companions even in his most psychotic moments. Thales, meanwhile, couldn't care less about who or what he has to defile or kill to further his plans.
- Fantastic Racism: As Arundel he is downright jubilant at the prospect of Rhea's death and humanity's supremacy. And if confronted by Flayn or Seteth in battle in his true form he says the following, keep in mind that those he is speaking to were not even born when what he talks about happened:Thales: Your eyes, hair, ears and blood... we remember it all! We remember how you ruined us. How you stole our light and condemned us to eternal darkness!
- Famous Last Words: On the Verdant Wind and Silver Snow routes, when he activates the nukes to destroy Byleth, Rhea, and Shambhala:Thales: For all Agarthans, let there be light!
- Irony: For all the association with darkness he has alongside his organization, even practicing dark magic, Thales longs for the light. His vendetta is motivated by a desire to embrace the light once more, and in his guise as Arundel, he finally finds peace when dying in the light on the Azure Moon route. His obsession with the light leads his entire nation to its downfall on the Verdant Wind and Silver Snow routes. He uses the last of his strength to launch "javelins of light" onto Shambhala both to kill his enemies and shine light upon the underground city at last (quite literally, since its earth ceiling collapses around it).
- The Leader: Is the leader of "those who slither in the dark."
- Not Me This Time: In Crimson Flower Chapter 17, when Kingdom soldiers start turning into Demonic Beasts, Hubert briefly questions whether Thales was responsible. It wasn't him; it was Dedue, driven to desperation by the Imperial army breathing down their necks.
- Nice Job Fixing It, Villain!: If he hadn't decided to experiment on Edelgard and her siblings, nobody would have known his faction existed. But he did, and it gets them wiped out in three routes and their leadership destroyed in the fourth.
- Prophet Eyes: His eyes are a solid white hue without pupils.
- Recurring Element: He's basically a classical take of the Gharnef archetype: an unnaturally ugly dark mage that manipulates events to his favor and even moreso, on the Verdant Wind and Silver Snow route, he attempts to resurrect a powerful figure with godlike powers (Nemesis) from the past to help his cause. To be more precise, he takes the most influence from Manfroy, an embittered Dark mage obsessed with the past oppression of his people, a hatred of the surface dwellers of the continent, and forces an influential noble with grand ambitions for the continent to ally with him in a teeth-clenched teamwork position. Ironically the target of his hatred, Rhea, takes influence from the more modern Gharnef Archetypes.
- Taking You with Me: Spitefully tries to nuke Byleth, Rhea, and Shambhala off the face of the Fódlan once he's defeated in battle. He's willing to destroy not only himself, but the last stronghold of his own people just on the off-chance it achieves his vengeance.
- The Unfought: On the Crimson Flower route, you never actually fight him since his group is technically working for you at that point. Instead the closing text says that Edelgard's new empire went to war with his group and took them down after defeating the Church of Seiros. Zigzagged on the Azure Moon route, as while you don't fight Thales specifically, you instead kill him under his guise as Lord Arundel.
- Villainous Breakdown: Once Byleth enters Shambhala, his otherwise stoic contempt drops, and he immediately barks orders to overload the stronghold's defense sentries and release the Titanus' inhibitors, all while he rants about the coming vengeance and his own troops' incompetency.
Class: Dark Bishop
A man with the appearance of a mage. Suitable for his appearance, he uses cunning schemes and tricks. A highly dangerous individual.
- Black Eyes of Crazy: His eyes are differing shades of yellow with black sclerae, and he's referred to as highly dangerous.
- The Chessmaster: Described as someone who relies on cunning schemes and tricks.
- Defiant to the End: When Byleth returns from what should have been their Fate Worse than Death sporting Sothis' power and a Death Glare, Solon realizes how screwed he is but chooses to go down fighting to the end with the last of his troops and fell beasts.
- Evil Old Folks: Having a bent back and needing a walking stick doesn't hinder his ability to be a bastard.
- For Science!: The reason he caused chaos in Remire. It brought absolutely no benefit to the group's goals (and in fact given he had to abandon his disguise as Tomas as a result, actively hurt them if anything), but he wanted to see what would happen.
- My Brain Is Big: His forehead is big and veiny, fitting for a character described as cunning.
- Nice Job Fixing It, Villain!: Him banishing Byleth forces them and Sothis to merge, allowing them to break out of his spell and cut him down afterwards.
- Obviously Evil: Pale, veiny forehead, black eyes, and a sinister expression all point to him being no good.
- Oh, Crap!: He freaks out when Byleth escapes his spell, and even more when he realizes how they did it.
- Recurring Element: Like Thales, he is the recurring Dark Mage like Gharnef, though he avoids falling into the smug minister sub-type despite being lesser to Thales by being ultimately loyal to him and expressing confidence that Thales will finish what he started. Additionally he's much more competent than the typical smug minister archetypes, he's able to operate undetected in the monastery without Rhea or Seteth ever suspecting him, succeeds in obtaining Flayn's blood, his plan to trap Byleth works and actually forces Sothis to give up her individuality and merge with Byleth to escape, and lastly, he doesn't cravenly beg for his life and remains defiant to the end despite Byleth having the power of the goddess and is utterly furious at him. Ironically, he managed to transfer most of the 'smugness' of 'smug minister' archetype he ended up avoiding into Kronya.
- Red Right Hand: His right eye is open abnormally far, has a different color than his left eye, and has unusual markings around it.
- Tron Lines: His gloves and staff have lines that glow dark blue.
- Villainous Valor: After his plans are thwarted, he makes a last stand against Byleth and their house.
- Weapon of Choice: Both times you fight him, he has a Magitek staff called the Staff of Circe.
- You Gotta Have Blue Hair: His hair is a pale blue.
One of "those who slither in the dark." She looks like a happy young woman, but she acts like a child and exhibits a brutal disposition.
- Advertised Extra: Her unique design, as well as some early pre-release material and her appearance in Heroes suggested she'd be a major antagonist. While she is the one who kills Jeralt, she herself ends up getting killed midway through the next mission, when Solon uses her as a sacrifice to take out Byleth.
- Ax-Crazy: This woman is not right in the head. Half of her Heroes quotes involve her going on and on about bloodshed and violence and pain.
- Beat Still, My Heart: When she's cornered by Byleth for the final time, Kronya requests help from Solon, who conveniently appeared behind her moments prior. Solon gladly obliges... by plunging his hand through Kronya's chest, slowly ripping out what's implied to be her heart and crushing it to activate his banishment spell. Kronya is still alive and screaming in pain while the entire scene unfolds.
- Do Not Call Me "Paul": Inverted. If you sic Leonie on her during her boss fight, she is enraged when Leonie refers to her by her alias Monica.
- Faux Action Girl: She's one of the assassins for "those who slither in the dark" but she would have failed her assassination attempt on Jeralt had Thales not interfered. The boss battle following is also rather easy compared to fighting Solon.
- The Friend Nobody Likes: It's made clear early on that neither Solon or Thales can stand her, the latter telling her to her face that the only reason he saved her from death was because she still had a use to him. That "use" being as fuel for Solon's ritual.
- Hate Sink:
- In the midst of many complex characters in Three Houses, Kronya stands out for her screentime and she spends all of those minutes making you REALLY hate her. Between being a Dirty Coward Faux Action Girl, killing Jeralt via cheap shot, reveling in taunting the hell out of Byleth, and being a considerably less complex character, it is very difficult for players to feel sorry for her when she's begging for help as she lays dying. She certainly fulfills the necessity of a character the audience can squarely hate, when the majority of the cast of characters are morally gray, and while this could apply to everyone from "those who slither in the dark", she also lacks Thales' overall leadership and cunning and Solon's Villainous Valor.
- This even extends into Heroes. Even then, Kronya gushes about her lust for bloodshed and repeatedly insults and threatens to kill Kiran/the player in her status quotes, summoning quote, Level 40 conversation and basic castle banter, in a game where Zephiel, Gharnef and even the human hating Grima are able to show restraint and some degree of respect.
- Human Sacrifice: Solon uses her as one to cast a powerful dark magic spell that almost sentences Byleth to a Fate Worse than Death.
- Knife Nut: While there aren't any actual daggers in the game as an usable weapon, Athame is more of a dagger than a sword and is even named after a type of ceremonial blade. Heroes adapts her into a Dagger unit using Athame.
- Laser-Guided Karma: The sadistic and cruel Kronya who relishes in killing receives "help" from Solon that ends with her becoming a Human Sacrifice begging to live.
- Monster Clown: The pale-white skin and eyeliner give off that kind of motif.
- Perky Female Minion: A youthful, childlike girl on a team led by stoic old men.
- Promoted to Playable: She makes her playable debut in Fire Emblem Heroes.
- Psychopathic Manchild: Described as someone who acts like a child but is very brutal.
- Recurring Element: She is basically the first female take of the Kempf archetype, with her being the closest "those who slither in the dark" have to a psychotic attack dog whose rank is in the middle between leaders such as Thales and Solon AND glorified mooks like Myson and Odesse, as well as having a tendency to mock and taunt those beneath her. As part of "those who slither in the dark" and their modus operandi, she can also be similar to many Dark Ladies that 'used to be virtuous in the past', but with a twist: Kronya and Monica are not the same person, whether Monica being virtuous or not in the past had no bearing with how Kronya could be such a bitch, meaning that she is a throwback to thoroughly unsympathetic dark ladies that was mostly used by Jugdral's Hilda and Elibe's Sonia.
- Smug Snake: She loves to taunt inferior beings and mock them for being unable to harm her. Not only does she quickly turn into a Dirty Coward when easily outmatched, whining about how unfair it is, she only succeeded at killing Jeralt thanks to Thales intercepting Byleth.
- Stripperiffic: The things coming out of her back seem to cover more surface area than her Leotard of Power, which also includes Cleavage Window, Underboobs, and Bare Your Midriff.
- We Hardly Knew Ye: She's killed off in the same chapter where she is formally introduced as Kronya.
- Villains Want Mercy: Has the gall to beg Byleth, whose father she just killed a chapter ago, to save her when Solon uses her as a human sacrifice.
A member of "those who slither in the dark" that appears on the Azure Moon and Verdant Wind routes. He shows up during the final battle between the Holy Kingdom of Faerghus and the Adrestian Empire at the Imperial Palace, bolstering Edelgard's forces.
- Decapitated Army: The moment he's defeated, any remaining underlings on the map retreat to fight another day, leaving only Imperial soldiers and Divine Beasts.
- Demoted to Extra: He appears in the penultimate battle of the Verdant Wind route, but he has no dialogue and essentially functions as just another Mook who happens to have a name.
- HP to 1: Comes equipped with the Bohr X spell, which reduces target's HP to 1 from a LONG range, similar to the Hel spell from the Jugdral series.
Class: Dark BishopA surviving member of "those who slither in the dark" that appears in the final map of the Verdant Wind route. He and the remaining members of the Agarthans support Nemesis and his forces during the battle.
- Last Stand: He and the rest of the Agarthans are this on the last map, as Shambhala, the main fortress of the Agarthans, has been destroyed.
