Figures that have shaped the past of Fódlan, transforming the continent into its present state.
Class: King of Liberation
Crest: Goddess/Flames (Major)
Voiced by: Naomi Kusumi (Japanese), Jamieson Price (English)
A former king of Fódlan in a time when the Goddess still roamed the earth and Seiros' opponent in a war ages ago. He once wielded the Sword of the Creator as well as the same Crest that Byleth possesses, said to have been gifted by the Goddess herself for his heroic deeds before he fell to darkness and had to be put down. His death paved the foundation of both the Adestrian Empire and modern Fódlan as it exists. Yet the truth of who he was and what he did remains a mystery to most.
- 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.
- Badass Beard: Has a bushy beard fitting for the strongest human who ever lived in Fódlan.
- Barbarian Longhair: He has long and wild hair appropriate for a man who was once a common bandit.
- 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 children's Crest Stones in place of her own.
- Decapitated Army:
- Averted in the backstory. While Nemesis' death by Seiros' hands was a major blow to his side, the records indicate the war continued for some time afterwards (Nemesis died in Imperial Year 91, while the war didn't properly end until Imperial Year 98 as a result of the remaining 10 Elites holding out until they were either defeated or offered amnesty).
- Both played straight and inverted on Verdant Wind, as with the revived Nemesis' death his undead army are no longer able to sustain themselves and crumble to dust. Nemesis himself can't really be harmed through normal means until all of his generals are slain.
- Did You Just Punch Out Cthulhu?: He killed Sothis, who was a full-blown Physical Goddess while she was alive, and drank her blood and had her spine turned into the Sword of the Creator. Granted, Sothis was asleep and exhausted when this happened and in no condition to defend herself.
- Evil Counterpart: To Byleth, made especially apparent after he returns as the Verdant Wind route's final boss.
- In the storyline, 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.
- This also applies in gameplay; his unique King of Liberation class has affinities for swords, brawling, and authority, Byleth's default strengths and three of the four affinities of their Enlightened One class. All of his weapon ranks are at least D with the lone exception being an E in Faith, Byleth's budding talent and the fourth affinity of the Enlightened One, highlighting a key point where they differ.
- Fallen Hero: The Church of Seiros states that Nemesis was once a revered king of humanity that was gifted the Sword of the Creator by the Goddess to combat wicked gods. He succeeded, but the power corrupted him and forced the Goddess to choose 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 Relic weapons out of their hearts and used their blood to offer prospective allies Crests, making himself into a king. His in-game text as an enemy states he then rallied his people to war to liberate Fódlan from a reign of deception, though as this is noted to have merely been a "pretense", it's unclear if he really believed in or cared about the claim. The atrocities he committed to gain power 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, on the advice of "those who slither in the dark," plundered Sothis' tomb and carried 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 offered to those who became the 10 Elites in exchange for their and their family's loyalty, eventually making Nemesis a king. Eventually, Rhea, Sothis's daughter, would take on the name Seiros and 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 a grudge against Seiros, and the belief that single combat is more honorable. Justified as by the time Byleth faces him, he is only a vengeance-fueled zombie that "those who slither in the dark" finished resurrecting as a war machine to serve as one last "screw you" to everyone for stopping them.
- Even in Heroes, there's still not much to him other than his belief that the strong rule over all. He's still quite bloodthirsty for Seiros, and is very taciturn, but eventually respects the Summoner during his Lv 40 confession.
- Greater-Scope Villain: His actions started the entire plot of Three Houses: By murdering Sothis and her children, Nemesis is the reason why the "Heroes' 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.
- Healing Factor: As seen in Verdant Wind's endgame, Nemesis has access to both Renewal and Cursed Power, the latter which only activates as long Nemesis is standing on Lamine's poisonous swamp.
- 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, resurrecting them using the Crest of Flames. While Nemesis retains his mind and memories, Claude notes that the 10 Elites and other undead soldiers are just his puppets, and when Nemesis is defeated, they all crumble into dust. This works twofold, as he channels his power through the Ten Elites to protect himself with a barrier and strengthen himself in the process.
- Kill the God: In the distant past, he murdered Sothis, who is generally worshiped as a goddess by modern Fódlan, and used her bones to create the Sword of the Creator.
- Leitmotif: "God-Shattering Star" plays during the final battle with him on the Verdant Wind route. Given the meaning of its lyrics, it also doubles as a Rousing Speech and Badass Boast for himself and his army.
- 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).
- Mighty Glacier: In Heroes, having very high Atk and Def and good Res, but low Spd.
- 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 (a mistranslation as in Japanese Edelgard makes no claim of knowing why they fought, only that it wasn't due to Nemesis becoming a fallen hero), and that Seiros killed Nemesis to take power in Fódlan. It's also stated that the relics were created by mankind. The dev interviews gives some more context to this as it confirms dragons did hold the positions of rulers of Fódlan in the distant past and that this motivated the Agarthans' hatred, who long after their war with the Nabateans would use Nemesis as a culmination of their desire to take the powers of the Nabateans for themselves. Said interview also notes however that for her part Seiros had no personal desire to rule over humans, but rather wished to preserve the peace and prevent another continent-wide war by taking over and establishing the Church.
- On the Verdant Wind (and to a less detailed extent on the Silver Snow) route, Rhea states that Nemesis was a bandit who somehow located and broke into the Holy Tomb, murdered the goddess Sothis in her sleep, then had unknown allies (by the end of the game revealed to have been "those who slither in the dark") forge the Sword of the Creator out of her remains, along with using her blood to give him the Crest of Flames. With this weapon of incredible power and his Crest resonating with it to grant even more power, he went to Zanado and massacred the Nabateans living there, his dark allies using the corpses and blood gained to create the Heroes' Relics and Crests. The sheer amount of blood that flowed and stained the walls of the land would give Zanado a new name, the Red Canyon. An enraged and traumatized Rhea was the sole survivor in Zanado (her other surviving kin being elsewhere at the time), and she took on the name Seiros as she organized people against him in what would become known as "The War of Heroes". Nearly a century later, she finally had her revenge, defeating him in battle and killing him, the war eventually ending some years later. In the aftermath, she used her authority and resources to rewrite history to make sure the remaining Nabateans wouldn't be killed to make more Heroes' Relics (as well as other purposes). Arundel, aka Thales, an actual Agarthan, refers to him as a "thief" in every route, supporting this version of the story. Maurice, one of Nemesis' allies, further implies that the "King of Liberation" title may have initially been a reference to how many people Nemesis had killed (i.e. "liberated" of their lives). A book in Abyss and his in-game info as a enemy unit give extra perspective on what is revealed in Verdant Wind. Namely his info as a unit states "Under the pretense of liberating Fódlan from a reign of deception, this king rallied his people to arms in the War of Heroes," suggesting he used deceit/manipulation to gain influence and go to war. An ancient text in Abyss, likely written by one of the 10 Elites, has them regret accepting "his offer," which could mean he offered Crests and Relic weapons to gain their and their clan's loyalty and legitimize himself as a king. It also indicates Nemesis never told at least some of them the truth of how he acquired the Crests and Hero's Relics, as the writer is at a loss as to what King Nemesis could have done to incur such "unyielding wrath" from Seiros.
- 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.
- Not-So-Well-Intentioned Extremist: His class description on Verdant Wind reads: "Under the pretense of liberating Fódlan from a reign of deception, this king rallied his people to arms in the War of Heroes." Documents in the Abyssal Library, and some developer interviews, imply that his followers genuinely did consider him a hero and liberator, unaware of the fact that he was mostly out for personal power.
- 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 was panicking to realize that Seiros had come to deliver Laser-Guided Karma.
- 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.
- Power Echoes: As a testament to his power, he speaks with an echo in his voice.
- Pre-Mortem One-Liner:"Full revenge!"
"Return to nothingness."
- In Heroes:
"Clear the way."
"I will break you."
- Promoted to Playable: Makes his playable debut in Heroes as a Grand Hero Battle unit.
- 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, who turned into a mad king with simple motives of conquering and showing off his strength. Had Seiros been the protagonist of the game, he would've been a take on the 'starter bandit' archetype that began with Gazzak; so he ends up being a take on a Gazzak that ascends into a Medeus.
- Red Baron: Was known as the "Liberation King"/"King of Liberation" in life.
- Sealed Evil in a Can: "Those who slither in the dark" kept 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 trying to kill him, and per his own admission in Heroes, Nemesis had just come out from a "thousand years of sleep".
- The Social Darwinist: In Heroes, his 5* level 40 quote has him state that it is the natural order for the strong to rule the weak.
- Suspiciously Similar Substitute: A thief that raided a temple, got some 'treasures' and with it, formed regalias that shaped one's country's history and left his mark on history? Nemesis is basically a throwback to Archanea's founder, Adrah, only having more prominence and his atrocities put more on highlight.
- Unwitting Pawn: He was used by "those who slither in the dark" in their plan kill Sothis as revenge.
- Villain Respect: In his 5* level 40 quote in Heroes, he acknowledges the Summoner's prowess in command.
- Villain with Good Publicity: Somewhat. House Hresvelg's secret records of the War of Heroes paints him as an important figure who sought to give mankind the ability to rule themselves and make their own fates without Nabatean rule, rather than having been a champion of the Goddess who fell to evil and corruption like the Church's official records claim. The truth is considerably more grey.
- 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.
- World's Strongest Man: During his conquest for revenge he seems nigh unstoppable, and it's only with the combined efforts of Byleth and Claude (and some trickery on Claude's part) that they barely manage to pull off a win. This is reflected in-game: with the 10 Elites behind him, he has the highest level and stats out of every enemy in the series, up to and including Rhea as the Immaculate One (unless you count her four health bars together) on the Crimson Flower route and Hegemon Edelgard, empowered by the Crest of Seiros and the Crest of Flames on the Azure Moon route. The only final bosses in the series comparable to him in raw stats are Ashera and Grima, the latter only matching him on Lunatic+, a difficulty option that is higher than Three Houses's Maddening mode. On Maddening, he has higher stats than Dheginsea, a boss considered by many to be the hardest boss in the entire series.
- 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
Crest: Seiros (Major)
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 her involvement in the war with Nemesis was motivated in part by her hatred for him, as he had stolen her mother's remains and slaughtered most of her kin. She's still around though, and as it turns out, these events did not have good effects on her mind.
- Arch-Enemy: Historically it was Nemesis, who she absolutely despised for betraying and killing her mother as well as slaughtering most of her race. In the Crimson Flower route it is Byleth, since in her Sanity Slippage she comes to see them as the second-coming of Nemesis and accuses them of stealing her mother and taking everything she has left from her. Her alliance with Dimitri during the War Phase is fueled by their mutual obsession of killing Byleth and Edelgard respectively.
- Ax-Crazy: If Byleth betrays her for Edelgard, she becomes obsessed with killing them, to the point where she no longer cares about innocents being caught in the crossfire so long as she is able to kill Byleth.
- 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 rewritten history with the founding of the Church and empire, kept it mostly sealed off from the rest of the world, perpetuated the Crest system by spreading the noble lie that Crests were gifted from the Goddess herself, and worked to resurrect her mother through the means available to her.
- 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 indirectly 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.
- Decomposite Character: Invoked in-universe in regards to her dragon form, the Immaculate One. As far history and lore is concerned, the dragon is merely a powerful creature that aided Seiros on her campaign against Nemesis, and beyond some few individuals (such as Wilhelm I and the Four Saints), no one knows before The Reveal that Seiros and the Immaculate One are the one and the same.Chapter 10's Narration: Long ago, the guardian Seiros made an appearance during this moon. She had been summoned by the goddess, whose soul was suffering as the flames of war raged across Fódlan. Some believe that high in the sky above Seiros, the Immaculate One's mighty wings are what powered the strong winds carrying the guardian and her forces into battle.
- 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 Crimson Flower 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.
- Dragon Their Feet: Pun aside, Dimitri's death and the fall of the Kingdom Army in Crimson Flower is due to their failed gambit at trying to bait the Empire into launching an attack on the seemingly vulnerable Church. Edelgard calls their bluff and directly takes the fight to Dimitri and his forces instead; Rhea and the Church are delayed by the rain, and by the time they finally arrive as back up, they're far too late to actually turn the tide of the fight.
- 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 (there even being a sealed casket in the church said to hold her bones), 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.
- Humans Are Flawed: In her Heroes level 40 conversation with the Summoner Seiros admits that she sees humanity as frail, ignorant creatures that cannot achieve anything without the aid of the the Goddess but her meeting with the various heroes and said summoner changed her mind. Since she presumably did not go through the events of Heroes in Three Houses, her actions, and blatant favoritism over those who have Crests, indicate that she still thinks this in the present.
- Interface Spoiler: In the Crimson Flower route, just in case there's any room for doubt when The Reveal happens, her Saint class' description unambiguously states she's the same Saint Seiros responsible for founding the Church of Seiros.
- 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 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.
- Lady of War: Fitting with her status as a demigoddess, she wears a white gown with armored elements and the rapier-like Sword of Seiros for an elegant weapon. Although she conducts herself with a serene demeanor, she's not above resorting to using her fists when disarmed and brutally stabbing Nemesis to death.
- Late-Arrival Spoiler: Heroes spoils the fact that she is actually a dragon.
- Light Is Not Good: In all three of her appearances (as Seiros, Rhea and the Immaculate One), she is depicted with strong ties to holiness, with White Magic as a proficiency of two of her personal classes (the third one being unable to cast magic altogether), yet some of her actions are more than questionable to say the least. That said, she doesn't truly fall into outright evil on any route other than Crimson Flower since that route is the only one where the person she believes to be her mother's vessel/reincarnation turns on her.
- Love Redeems: One of the few Fire Emblem final bosses who can survive and be redeemed, at the end of the Silver Snow route if the player A or S-Supports her, an S-Support allowing for more complete redemption than A (wherein she retires instead of actively helping reform Fódlan as she does if S-ranked), and failing to achieve at least A-rank resulting in her death.
- 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. In fact, as the final boss of Silver Snow on Maddening difficulty, she has the highest HP of any non-player unit in the whole franchise!
- Mighty Glacier: In Heroes, where she has one of the best Atk and Res stats and is even tankier compared to her archenemy Nemesis, but is slow to compensate.
- Missing Mom: Her main motivation is to revive her mother Sothis, who she believes is the only one who can fix Fódlan's problems due to being the Progenitor God.
- Multicolored Hair: Seiros in the opening cinematic of Three Houses is shown to have mainly blonde hair with light green tips, which her appearance in Heroes follows. Averted in the Crimson Flower route where her hair is wholly light green like in her Rhea identity.
- 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.
- Parental 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.
- Pre-Mortem One-Liner:
- Saint Seiros:"You must be purified!" (Three Houses and Heroes)
"It is your time!" (Three Houses and Heroes)
"Suffer for eternity!" (Three Houses)
"Traitor! (Three Houses)"
"You have been judged." (Heroes, reused from Rhea's criticals)
"In the name of the goddess." (Heroes, reused from Rhea's criticals)
- The Immaculate One:"I will tear you down!"
"This will be your end!"
"Banish into the Abyss!"
"You will not be forgiven!"
- Saint Seiros:
- Promoted to Playable: Initially, she's essentially playable as a Duo unit with Female Byleth in July 2020 in Fire Emblem Heroes, but only under her identity as Rhea. She was released as a Mythic Hero of Anima later on in late January 2021 in Heroes, fully making her playable in that game.
- 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.
- Revenge: In the past, Seiros founded both the Church of Seiros and co-founded the Adrestian Empire along with Wilhelm I with the sole intention of raising an army strong enough to defeat Nemesis' and avenge her people. Judging by the records left by Wilhelm I and one of the 10 Elites in the Abyssal library, it's implied many of her allies and enemies at the time were left in the dark about this.Rhea: (...) All I could do was wander across Fódlan clinging to my desperate desire for revenge. I called myself Seiros, fostered the founding of the Empire, and prepared to oppose Nemesis and his followers.
- Semi-Divine: She's the goddess' last daughter and creation.
- Sins of Our Fathers: Averted. One of the books in the Abyssian library reveals that after Nemesis death and the war turning in her favor, Seiros demanded the deaths of the Ten Elites while also going out of her way to make clear their scions and clans would be guaranteed safety if they surrendered.
- Technophobia: The Abyss library strongly implies she has been deliberately slowing down technological progress in Fódlan out of lingering fear that modern humans would misuse it just as the Agarthans did.
- Unusable Enemy Equipment: Her Seiros Sword cannot be obtained by the player.
- Walking Spoiler: It's really hard to talk about her without revealing her true parentage, or that she's the true identity of Rhea.
- Weredragon: She's capable of transforming into a huge white dragon called the Immaculate One. As a Mythic Hero in Heroes, this is her principal means of attack.
- 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.
- Aerith and Bob: Dominic and Maurice in particular stand out for being utterly normal next to names like Blaiddyd, Fraldarius, and Gloucester.
- Ancestral Weapon: The Crests and the Heroes' Relics are passed down from generation to generation in their noble bloodlines.
- And Then John Was a Zombie: Officially most of them died due to infighting after the war. However, in truth some were killed by Seiros' forces during the closing years of the war and there are implications that in addition to Maurice a number of them became the Nabatean-like demonic beasts around this time period too. A letter written by one of them ends with an ominous statement that "the evil" is overcoming their body in some way, and other dialog makes mention of rumors of others who became demonic beasts.
- Back from the Dead: On the Verdant Wind route, "those who slither in the dark" resurrect ten warriors who are named as 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 (though their zombie versions seem to lack any free will regardless).
- 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. The rest are unusual choices of classes that may not properly reflect the skill proficiencies of their modern day descendants. Most notably, two of the Ten Elites, Goneril and Fraldarius, are actually in gender-locked classes that their descendants Hilda and Felix can't access.
- Healing Factor: In the last chapter of Verdant Wind, the skill Cursed Power allows any elite who stands in Lamine's deadly swamp to recover a bit of their HP each turn.
- Heroic Lineage: They are a cornerstone of the Church of Seiros and Fódlan's history and their descendants bear their Crests.
- Historical Hero Upgrade: Maybe. While they're hailed as heroes in the present day, the Ten Elites were allies of Nemesis during the War of Heroes. Rhea states that they were bandits who were to some degree complicit with his slaughter the Children of the Goddess, but a letter in the Abyss library indicates that at least one of them was ignorant as to how he came by such power and to why Seiros hated them so much. In either case, after Seiros won, she canonized them as heroes to encourage the use of Crests among their descendants. In modern times only the Four Saints and Agarthans (and perhaps a few others) are fully aware of their true nature. An interview confirms that to many people of the time the 10 Elites and Nemesis were heroes, and that Seiros and her allies had to keep this in mind if they were to rewrite history and maintain peace while doing so.
- Locked Out of the Loop: If one of the books in the Abyss library is any indication, at least some of the Elites didn't know about the origins of their Heroes' Relics nor that Nemesis' caused the Tragedy of the Red Canyon, or indeed that the tragedy even happened.
- Long-Lived: Receiving Crests gave them lifespans that spanned centuries. Indeed, the Nemesis war alone spanned nearly a hundred years. It's unclear how long they might have been able to live, but Maurice proved able to live for over a thousand years, albeit in a nonhuman form. An old record in the Abyss seemingly written by one of the Elites mentions their long lives.
- 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 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, in the vein of the Twelve Crusaders of Jugdral. Unlike the other members of this archetype, however, the 10 Elites received a Historical Hero Upgrade and forcibly stole the power from the divine entity.
- 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 used the blood of the murdered children of the goddess to give themselves Crests.
- 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. In most cases, their bearers are instead revealed to be the Four Apostles, who apparently reconciled with Seiros sometime after the war in an attempt to resurrect Sothis. Their absence from history is due to most of them retreating to their home villages and living quiet lives.
- 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.
- Ambiguous Situation: It's never elaborated upon whether Macuil did gift his blood or not to the people of Adrestia like Seiros and the other saints did. On one hand, while it is generally assumed he did so in-universe, no playable character bears his Crest and Macuil's disdain towards humans as seen in Claude's paralogue makes unlikely he would have shared it willingly. On the other hand, Edelgard and Constance's B-support reveals House Nuvelle managed to conceal their Crest of Noa by making it pass like Macuil's through magic, the latter which, per the Empire's records, was already present in Adrestia prior to the founding of House Nuvelle, leaving the truth of the matter ultimately ambiguous.
- Breaking the Fellowship: Implied to have happened to them when the War of Heroes came to an end. While Seiros remained in control of the Church under a different identity, Indech went into seclusion at the bottom of Lake Teutates, Macuil left towards the Sreng Desert, and Cichol went into hiding to take care of his daughter Cethleann, who had previously collapsed into a coma as a result of overextending herself during the war.
- Faking the Dead: All four of them fake their own deaths, with Indech and Macuil taking the forms of dragons, while Cichol and Cethleann take on the new identities of Seteth and 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 progenitor and most of their kind 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) and readily killing any humans who reject his warnings to leave. Indech is neutral, secluding himself from the world and killing those who agree to 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: While all of their names come from Celtic Mythology, Macuil's name comes from one of the Tuathan Dé Danann, 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 perhaps 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. But in truth averted, as 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.
The Four Apostles were Noa, Chevalier, Timotheos, and Aubin.
- Blood Magic: Balthus' mother originates from Kupala, a village where a ritual involving red liquid was given to the village by an elder when under siege by threats and many in the village had been injured severely and were at death's door. Half of them treated with this liquid did not improve, and vanished afterwards to an unknown fate, and the other half miraculously recovered and obtained the Crest of Chevalier. Yuri suspects the elder who lived with him and his mother saved his life by doing the same, and thus where his Crest comes from. Though since the elder died years ago, he decides to push it aside since he can't verify it in his supports with Balthus.
- Dark Secret: Noa kept her Crest a secret out of fear of people misusing her Crest. Her descendants likewise kept it secret using magic to deceive the entire empire by making it resemble Macuil's Crest.
- Foil: To the Four Saints, as while the Saints became legends, they faded into obscurity.
- They are also this to the 10 Elites. Like them, the groups were blessed by the goddess. Where as the 10 Elites forcefully took the blood of the Nabateans, the Apostles apparently were willing, due to them apparently being firmly on Rhea/Seiros' side.
- Last of Their Kind: They were to be the end of their Crest bloodline in order to ensure the Chalice of Beginnings would never be unsealed, however, each of their Crest bloodlines survived into the present. It's implied Aubin himself was the elder who Yuri's mother took in and saved Yuri in his youth, making him the last living one until he passed away not long after.
- Posthumous Character: Like the 10 Elites and the 4 Saints, they are said to have died a long time ago.
- Shrouded in Myth: So few records of them have survived to the present day that only their Crests remain as conclusive proof of their existence aside from of course Rhea/Seiros' own recollection of them.
- Transhuman: Just like the 10 Elites and the 4 Saints, they were blessed by the goddess in the past and passed these Crests down to their descendants. The fact they have Heroes Relics (one being a replica relic made after the War of Heroes, but the other indicated to have been used during the War of Heroes itself) and the Crest Stones of Timotheos and Noa are inside of Nemesis's Dark Sword of the Creator during his boss fight on Verdant Wind indicates they truly were humans like the Elites, but they likely were actually on or ended up on Seiros' side considering they were willing to try and help her revive Sothis.
Wilhelm Paul Hresvelg I
Crest: Seiros (Major)
The first Emperor of Adestria, it was Wilhelm I who joined forces with Saint Seiros and led his fledgling nation against Nemesis in the War of Heroes to unite Fódlan and free it from the now-corrupted king. Though he did not live to see the end of the war, leaving his son Lycaon I to finish his path, he is still revered by the Empire as its founder over a thousand years later.
- Locked Out of the Loop: Downplayed. While he clearly knew more of the true story behind the conflict of Seiros and Nemesis than the present public record shows, given how he wrote a secret history to be passed down the line of emperors, his version of the events is missing some key points which leave the overall context of the war incomplete, implying that just as Nemesis never told his allies about the truth of the relics and crests, Seiros never told Wilhelm about what happened at the Red Canyon.
- Irony: Wilhelm was the founder of his line as well as an ally and even friend of Seiros, something that Rhea even in her more insane moments supports. His most recent descendant, Edelgard, views the Church as her one of her greatest enemies and on Crimson Flower will even end up killing Rhea/Seiros.
- Our Founder: The first Emperor of Adestria. In fact, the year of Adestria's founding is dated as Imperial Year 1 of Fódlan's calendar.
Loog von Blaiddyd
The founder of Faerghus, Loog fought a war of independence in Imperial Year 747 to separate from the Adestrian Empire in the War of the Eagle and Lion. Defeating the empire on the Tailtean Plains in Imperial Year 751 lead to the church officially recognizing the Holy Kingdom's independence, and Loog was hailed henceforth as the King of Lions.
- Irony: Despite Faerghus' idolization of Loog as a symbol of chivalry, records in the Abyss indicate Loog's rebellion was only successful thanks to the machinations of "those who slither in the dark" providing Relic weapons and his strategist and friend Pan being one of their number. The irony goes in further considering in the present day those same benefactors have no problem destabilizing the very kingdom they helped him build.
- Our Founder: The first king of Faerghus.
