"Servant, Archer. I, Tam Lin Tristan, have come in response to your summons. I swear never to bring disgrace upon my knightly name... As if, kyahahahahaha! You really don't know a thing about me, do you!? That's hilarious! I might actually like you! Anyway, let's be friends. I, too, champion Justice after all."

Summoning Line before clearing Avalon le Fae

"I am Baobhan Sith, of the crimson heels. That's enough of an introduction, right? No matter where I go or what I do, I am who I am. I'll do as I please here, and turn you all into mincemeat."

Summoning Line after clearing Avalon le Fae

A faerie who serves Queen Morgan as part of the Knights of the Round Table in Avalon le Fae. She was raised as a witch but granted the name and powers of Tristan, a Round Table Knight from Proper Human History; hence her "Archer" class. She is considered to be the "daughter" of Morgan, and thus treated as the future successor to the throne: a position she uses to indulge her bloodlust and privileged personality.

Her true identity is Baobhan Sith, a fae who was regularly taken advantage of by other fae for her genorosity to the point she was killed repeatedly. She would be found by Morgan when she was on her last life and adopted by her, Morgan instructing her to be cruel so that the other fae wouldn't take advantage of her again and she wouldn't have to die.

She appears as one of the main antagonists in "Lostbelt No. 6: Faerie Round Table Domain, Avalon le Fae". Her event appearances include "Arctic Summer World", "Chaldea Fairy Knight Cup", and a major role in "Mystic Eyes Symphony" as its mastermind in order to get pictures of all of Chaldea's Servants' feet.

A-J

• Adopted into Royalty: Her being adopted by the fairy queen Morgan would already give her a huge boost in notoriety, but the reveal that fairies actively shun other fairies who drink blood makes the jump even more impressive as she went from being in the bottom of the fairy society for being a fairy vampire to belonging to the top of the society. This is reflected in her Blessed Successor skill, which is described as giving her power and authority that only she has due to being Morgan's recognized daughter. Gameplay wise, this lets her seal her enemies NP and skills while charging her own, reflecting her authority.
• Adoption Angst: This starts rearing its ugly head once Morgan's biological daughter (by faerie standards) Altria Caster shows up. Baobhan Sith becomes obsessed with defeating Altria Caster in a Magecraft duel to cement her status as Morgan's true daughter once and for all, but each time Altria emerges the victor and rubs it in her face, kickstarting her Sanity Slippage.
• All Girls Want Bad Boys: Deconstructed, as her infatuation with Beryl despite his clear lack of interest leads her to do terrible things on his command that eventually come back to bite her and Morgan.
• All Women Love Shoes: She is absolutely fascinated with the concept of high-heel shoes after Beryl started to talk about Proper Human History. She puts a lot of effort into her hobby as a shoe collector, wanting to create the greatest pair of shoes ever made in the future and turning her bedroom into a collection of shoes and fairy feet. All this seems like a twist on the tales about Baobhan Sith and how they try their best to hide their hooved feet.
  • In addition, she also briefly considers making heels out of a Holy Grail in My Room, before being told of other things servants have used it for like bells or rice dishes, discarding the idea so as to not lower herself to that level.
  • She also gifts her Master a pair of fashionable shoes for their birthday, after seeing all they have is work shoes.
  • Finally, her creating shoes is most of the point of the "Mystic Eye Symphony" event, which requires the cast to provide her with shoe scans of the Servants.
• Ambiguous Situation: While the other two Tam Lin's 3rd ascension has them partly reverting into their Calamity forms its never clarified why Baobhan Sith's 3rd ascension is the way it is. It's possible this might have been a previous appearance of hers before Morgan found her, the result of the Fetch magecraft rotting her body, or even Cernunnos' influence on her form given his theme is meant to evoke the idea of a girls last happy dream and Baobhan Sith noting how everything before her third ascension felt like a happy dream.
• Anti-Magic: Notably, she has Magic Resistance Rank EX, meaning most Magecraft can't touch her. It's even higher-ranked than Morgan's, who is just at Rank A. Her profile even calls her resistance to magic "extraordinary".
• An Arm and a Leg: A recurring theme with her numerous deaths is that she would always end up losing her four limbs before dying. While Morgan was able to save her before this would happen to her one last time, her limbs have been torn up by the time Spriggan uses Baobhan Sith as a blackmail tool to make Morgan step down and get executed.
• Ape Shall Never Kill Ape: All Tam Lin are ensorcelled to die if they ever kill another Tam Lin.
• Armed Legs: Her shoes have blades on them that she uses for various devastating kick attacks.
• Ax-Crazy: From the get go, she's very eager to spill blood and make people scream. And from her third ascension onwards, her voice lines and overall personality become much more disturbed and insane than that. She's killed over 400,000 fairies by herself in her 100 years long career as a Fairy Knight.
• Black Magic: As Morgan's "daughter" and one of the only fairies who is an explicit magician, she practices this. Even her Noble Phantasm, Fetch Failnaught, is actually a Curse that weaponizes the Fetch magecraft Beryl taught her, creating a "reflection" of the soul that reflects any damage done to it on the original.
• Bloody Murder: Plenty of her attacks specialize in gushing blood from people's wounds, or involve bathing in it, or spreading it around through a pieroette as in her extra attack. Even her Noble Phantasm, Fetch Failnaught, causes her foe to erupt in spikes and blood. Fitting her true nature as Baobhan Sith, she has plenty of things she needs or uses blood for.
• Boisterous Weakling: She has the loudest bark but the softest bite of the three Tam Lin. Unlike Melusine and Barghest who were born as superfaerie monsters, Baobhan Sith is nothing special without the protection of her status or her Gifted Name giving her a power up. Additionally, her Tam Lin powers do make her one of the strongest characters in the Lostbelt, but this becomes inconsequential when the story repeatedly pits her against the few characters who are straight-up her superior, or situations where her Tam Lin advantage is nullified. She also vastly overestimates just how far said advantage can take her, as seen when she claims to be stronger than Woodwose, a faerie who even Morgan herself holds in the highest regard. When she actually tries fighting seriously, she's beaten back without any trouble multiple times by characters like Muramasa and Altria Caster, and none of the heroes regard her as anything more than a nuisance, something that infuriates her.
• Bookends: Her introduction in Lostbelt 6 has her throwing members of the royal court into the Great Pit. Her last scene is her getting thrown into the same pit by other members of the court.
• Boss's Unfavorite Employee: The Master of Chaldea gives her a surprisingly chilly reception for her Valentine’s Scene. With most servants they often acquiesce to any servant demands or requests. But for Tristan the master refuses to even move aside and let her sit on their bed, the reception to the chocolate is somewhat subdued and the Master refuses to comment on it openly.
• Broken Bird: Though she's quite happy and sadistic in her first and second ascensions, her Third Ascension fully displays her broken qualities, mainly from her past.
• Brutal Honesty: Altria Caster within the Caster servant's profile from FGO Material X lampshades this trope as she remarks that Baobhan Sith is a fairy who didn't lie, and she always says whatever is on her mind.
• Cinderella Plot: In a sense, her backstory and life could be considered as one, if in a highly twisted form of it. In fairy society, Baobhan Sith was considered extremely low class given her nature as a vampiric fae who needs human blood to survive. But given she desired to be loved by others, she did every chore tirelessly until her limbs fell off from exhausting herself to death or being ripped apart by the fairies for fun. Unfortunately, fairies have reincarnative immortality, so Baobhan Sith would simply return and the whole cycle would begin once more. It takes Morgan, who sympathized with her plight and kindness and who in a sense is Baobhan Sith's Fairy Godmother, to break the cycle and raise her to the point she can be a real princess. She also has a fascination with heels and her Riding Skill is Ranked A, justified as her spurring the land beneath her heels. Both of these bring to mind how Cinderella had a pair of glass slippers that identified her and fled the ball at midnight, while Baobhan Sith has a tendency to run home and cry to Morgan.
• Collector of the Strange: She might have started the hobby of shoe collecting, but her already twisted psyche made her start collecting fairy feet as well. Because what are shoes but something to cover your feet, right?
• Combat Stilettos: She wears fancy platform shoes in her First and Third Ascension, with her being able to even grow spikes from the heels to stab enemies. In Second Ascension, her pair of footwear doesn't even have soles, meaning that she is standing merely by large spikes.
• Commonality Connection: Her line for Marie Alter has Baobhan Sith invite the "Black Queen" to a tea party for royals who were murdered by their own people. She then offers to turn everyone they hated into dolls whose heads they can rip off and feed to each other like macarons.
• Cute and Psycho: She loves treating people like toys she can play with until they break, and looks adorable while doing it.
• Dangerous Forbidden Technique: The Fetch magecraft that Beryl taught her allows her to make death curses from any distance, telling her he couldn't use it himself due to being too advanced for him. The actual reason is that using Fetch rots the user's soul, eventually killing them.
• Dark and Troubled Past: Baobhan Sith was originally a fairy who just wanted to make everyone she met happy. But because fairies are naturally Ungrateful Bastards, she would work tirelessly before being thrown aside and dying with her limbs torn off with no one caring about her death. With her current life as Grimalkin's maidservant/prostitute being no different. One day Morgan found Baobhan Sith on the verge of death, with her showing the savior gratitude no other fairy has shown her. After coming across her multiple times across her many lifetimes, Morgan decided to save Baobhan Sith's life by adopting her as her child. The fact that she is such a cold-hearted knight is because Morgan found out that she won't be able to reincarnate anymore so she told her that she will never find true happiness if she lets herself be used by others and should live her life to the fullest.
• Die Laughing: Her last words as she's hurled into the Great Pit are nothing but a weak laugh.
• Dying Curse: She falls into the Great Pit where Cernunnos sleeps, cursing the faeries for what they did to her and her mother Morgan, and cursing herself for letting this all happen. According to Grímr the Sage, this was enough to restart Cernunnos's Divine Core and start the Great Calamity.
• Establishing Character Moment: She crashes a meeting between Morgan and her subordinates, kills several officials for fun by making them jump off a cliff against their will, and then makes the survivors sing her praises. In terms of her introduction to the party, her brief meeting with the Protagonist and Altria Caster establishes her sadism and love of being unncessarily cruel as she taunts and messed with Altria for no reason.
• Evil Knockoff: Thanks to possessing a copy of Tristan's Spirit Origin, she has access to a similar bow which she uses for some of her attacks. Although hers is a bit smaller and more sinister looking.
• Fantastic Racism:
  • A case where she's the victim of it. Given she's a fairy who needs to feast on human blood for sustenance, other fairies see her as doing the equivalent of drinking sewage and treated her like trash for it.
  • She also has an instinctive revulsion for the Fae of Faerie Britain. When she first runs into Altria Caster in Gloucester, she's surprised that she doesn't feel any hatred even when talking to the country girl.
• The Fashionista: Always on the lookout for new trends in fashion, especially shoes.
• Foil:
  • She seems to be one to Mordred. Both of them are children of Morgan, though Baobhan Sith was adopted by Morgan's Lostbelt self while Mordred was the biological child of Morgan's Proper Human History self. Both of them wear red, but Baobhan Sith dresses much more femininely while Mordred is more masculine-toned. Baobhan Sith is also refined, sadistic and evil while Mordred is tomboyish, rough but good. They both also have a rivalry with their respective Altria over who is the true heir to Camelot, with Mordred claiming it as she's the biological child of Altria despite being rejected by her, while Baobhan Sith is the adopted but chosen heir of Morgan despite Altria Caster being the fairy equivalent of Morgan's child. Finally, Baobhan Sith is a beloved daughter of Morgan that Morgan is willing to give up her kingdom for. Mordred was somewhat raised as a pawn for Morgan to destroy Camelot with.
  • She's also one to Melusine. While they're both loyal to their respective "mothers", Baobhan Sith has a relationship based on genuine love with Morgan while Melusine's relationship with Aurora is more manipulative on Aurora's part. Baobhan Sith also gleefully does evil acts that she was allowed by Morgan to do while Melusine is heavily conflicted by the orders she receives from Aurora. Finally, Baobhan Sith remains loyal to Morgan to the very end, breaking down as she dies in front of her. Melusine murders Aurora herself, betraying her wishes.
  • She also has parallels with Beryl, the object of her affection. They are both sadistic killers who wear red, they both use curse-based magecraft (though Beryl specifically has her use Fetch so that she bears its penalties), and they both have ties to Morgan. On the surface, they’re quite similar (likely one reason Baobhan Sith is so enamored with him), but they are quite crucially different beneath the surface. Baobhan Sith commits her evil deeds out of revenge for the ungrateful Fae abusing her, because she’s genuinely NOT WELL mentally, and she literally does not know better, since that is how Morgan raised her to be. Beryl, by contrast, commits his hideous acts without any trauma or pain compelling him to, is fully aware of how despicable it is, and is totally unrepentant about it. Their attitude towards others (particularly each other) is also quite distinct. Baobhan Sith is a nasty bitch to nearly everybody, but she truly adores her mother Morgan, and her affection towards Beryl appears to be entirely genuine. Beryl instead acts polite and friendly to most people, but is a complete psycho inside who harms the ones he cares about the most. Any affection he has for Baobhan Sith is expressed by encouraging and enabling her atrocities until the point it destroys her.
  • She also serves a foil to Barghest, her fellow Tam Lin. Barghest got her rank as a Tam Lin after many heroic exploits and having displayed the proof of her strength, whereas Baobhan Sith became a Tam Lin through Nepotism and actually lacks the power to live up to the name. Barghest is highly respected by the other faeries, but everyone hates Baobhan Sith for her numerous killings. Barghest has a noble heart who wants to protect the people of Faerie Britain, but Baobhan Sith doesn't care for any of them and spends most of her free time killing them. Barghest has many lovers, but she genuinely loves every single one of them, but Baobhan Sith is slut-shamed for being a prostitute. Both of them lose their Gifted Names, but Barghest is allowed to keep her rank as a Tam Lin and is still treated with respect during a crisis situation, while Baobhan Sith eventually loses her rank and status after she has stolen the Garden of Lost Will. Barghest converses very formally and femininely despite her tall and muscular build, whereas Baobhan Sith speaks very rudely and less feminine despite her girly appearance. Barghest eventually awakens as a calamity, while Baobhan Sith becomes a sacrifice for Cernunnos to awaken him.
  • She is also one towards Elisabeth Báthory, who Baobhan Sith is an Identical Stranger towards. Both are related to vampirism in some regard, though while Baobhan Sith is an actual vampire, Elisabeth is technically not one, as her connections to vampirism comes from her Carmilla self (who was influenced by the false legend that sprung up around Elisabeth later). They has interest in something related to the arts, as Baobhan Sith is The Fashionista while Elisabeth wishes to become an Idol Singer. However, while Elisabeth is Affably Evil, Baobhan Sith is pretty much a Jerkass. Ironically enough though, Elisabeth was actually more evil when she was first introduced in Fate/EXTRA CCC, but thanks to Character Development, Elisabeth is now trying to become a better person while Baobhan Sith Used to Be a Sweet Kid until Morgan came along, and taught her cruelty.
• For the Evulz: Her reasons for torturing and killing faeries are for no real reason beyond that she can. Luckily this seems to only go towards fairies, and as Barghest notes in Chaldea, she doesn't carry as much of these tendencies as there are not many fairies to deal with there. This gets subverted later on as it's an established self-defense mechanism to make sure that she doesn't get used in the way that caused her pain in her previous life.
• Hated by All: She's hated by everyone in her Lostbelt for her vicious temper, homicidal tendencies, self-absorbed nature, and her infatuation with Beryl Gut. Even her adoptive mother Morgan is content to ignore her most of the time, and Beryl similarly would rather indulge his hobbies than spend time with her. Of course, she's repaying her fellow fairies for how badly they treated her and Morgan allows it to happen.
• The Hedonist: She lives her life to ultimately pursue what she enjoys and to satisfy her amusement, be it the cries of the fairies and tormenting them, and finding it fun to emulate Proper Human History.
• Hidden Depths: She appears to be your run of the mill Cute and Psycho who loves to hurt people and has an obsession with shoes. But her Third Ascension and lines afterwards showcase a very different side to her. She appears to keep her bloodthirsty tendencies, but it's wrapped with an intense desire to be loved or wanting affection from others, be it her mother, Morgan, the Master, or people in the Lostbelt. As can be seen in Dark and Troubled Past, it's likely this is how she was before Morgan adopted her and taught her cruelty. A further conversation with Beryl after Barghest and Tam Lin Lancelot report to Morgan further cements this, as she confides in Beryl whether or not Morgan loves her and if she can even find a soulmate given she's a "fairy who everyone hates".
• History Repeats: In three ways.
  • Like the original Tristan, ill-advised love leads her astray and results in her poisoning and eventual death.
  • Similarly to the Camelot's Singularity Tristan, both are heavily traumatized beings who become bloodthirsty sociopaths in retaliation for the suffering they went through and their deaths are similarly gruesome.
  • Lastly, to the Priestess of Cernunnos. Lostbelt Britain was made by the Six Faeries killing Cernunnos and chopping his Priestess into pieces, keeping her alive through their magic so they could make a new species of humanity from her pieces that they could enslave and benefit from. Baobhan Sith's various lives ended up with her limbs rotting or being chopped off after working herself for the good of the fairies, and yet ironically her final death via falling into the pit leads to Cernunnos' awakening and Faerie Britain subsequently becoming FUBAR to contrast the Priestess's own circumstances leading to Fairy Britain's creation.
• Humiliation Conga: Aside from her Trauma Conga Line (see below), Baobhan Sith's status as one of the Tam Lin and Morgan's appointed successor gave her immunity and lots of power to abuse the faeries of Britain. Most of the citizens as well as the Chaldean are in agreement that Baobhan Sith doesn't deserve any of the aforementioned privilege, which is why none of the faeries and humans pay respect to her. She's also clearly the weakest of the three Tam Lin, as she never poses a real threat to the Child of Prophecy and Chaldea in any fight; in fact she loses every single time. She's eventually stripped off of her status as a Tam Lin and Morgan's successor after she has stolen the Garden of Lost Will. Not even Barghest, who got stripped of her Gifted Name, loses her status as a Tam Lin and she's still viewed in respect.
• Hypocritical Humor: One of her lines in her early Ascensions has her declaring Elisabeth Báthory as seriously nuts and wonders if she's been like that from the start. Now compare this to how she acts by her own Third Ascension.
• Identical Stranger: She visually has many similar features to Elisabeth Bathory, despite lacking any direct relations at first glance. The similarities are made explicit when one of Morgan's guards off-handedly mentions sealing up the door to her room, which is believed to be the cause of Elisabeth's death. Which makes sense given they're both related to vampires in some form.
• In-Series Nickname: Beryl loves to call her "Lady Spinel", spinel being another semiprecious gem and one that is often colored red.
• Irony:
  • In her Noble Phantasm, she drives an arrow into her opponent's heart with a hammer, so she is a vampire doing the staking.
  • Even though she is the Token Evil Teammate of the Fairy Knights, she is the only Fairy Knight who is not meant to be a Calamity that shall destroy Britain. Of course, she did end up kickstarting a Calamity by accident in the past, and ends up awakening a Great Calamity.
  • Despite effectively becoming Altria Caster's Unknown Rival, their initial meeting in Gloucester before they knew each other's identities suggest they could have real friends, as Baobhan Sith lacked any innate revulsion for Altria given her status as an Avalon le Fae. Even in the throes of her mind and soul rotting and at death's door, Baobhan Sith still found herself thinking fondly back to their first meeting, even if she couldn't remember Altria's name or even Gloucester specifically anymore.
• Jerkass: Extremely rude to others and doesn't give a shred of thought to them, hates poor fairies with a passion, loves killing for fun... it's no wonder she's regarded as the most hated of the three Tam Lin of the Round Table.

K-Z

• Kick the Dog: A trope that goes both ways with her.
  • When she hears that Altria Caster and the protagonist need an invitation to get into a high class auction, she mentions that she has some leftover invitations... then tells them that there's no way in hell she's giving one to some low class scum and that they should go crawl in the dirt like worms as befits their social status for the rest of their lives. However, both Altria Caster and the Protagonist note afterwards there was something off about her attitude, almost like she was ribbing them rather than being genuinely malicious.
  • She was the one who suffered from this from the fairies, doing their tasks for them out of a desire to be loved, only to be ripped apart mercilessly afterwards.
• Leaning on the Fourth Wall: Played with. Baobhan Sith finds the Protagonist's ability to see normally invisible values such as Bond levels to be amusing and she thinks they should get their head checked.
• Leitmotif:
  • Her theme, "Scarlet Dancer", was specifically requested by Nasu to be in the same vein as CCC battle music for the Alter Egos, reflecting Tristan's similar nature with her psychopathy and dramatic flair.
  • A sinister orchestral arrangement is used as Cernunnos' battle theme, emphasizing her role in awakening him and her similarities to his priestess.
• Love Makes You Dumb: She loves Beryl of all people and wants it to be reciprocated, which makes her go along with almost anything he teaches her without question. Which naturally makes it easy for Beryl to manipulate her. One example includes partaking in atrocities against allies of her mother to impress Beryl. More pressing examples include her learning Fetch Magecraft from Beryl, which while it hurts her foes, it also rots her soul. Another example is her aiding Beryl in harming Woodwose, cementing the lie that Morgan wants him dead as Baobhan Sith is her daughter.
• Muscles Are Meaningless: Despite her lithe physique, she inexplicably has A-ranked Strength, which makes her even physically stronger than the significantly burlier Barghest (B+ Strength) and even her own Tam Lin namesake Tristan, a muscular man himself.
• Nepotism: It's made clear to everyone that the only reason she's a Tam Lin is due to being Morgan's adopted daughter as it's otherwise noted that she does nothing to help the kingdom run. She's by far the weakest of the three Tam Lin, as she loses every time she fights the Child of Prophecy, and most don't view her as a threat compared to the other Tam Lin's; Muramasa caught both her and Barghest off guard when he tried to attack Morgan, yet he comments that Barghest would actually have been a challenge if he had fought her head on, and makes no reference to Baobhan Sith's power, implying he doesn't think she's a threat by comparison.
• Odd Friendship:
  • According to Barghest, Baobhan Sith gets along well with Galatea thanks to a shared interest in making shoes. During "Mystic Eye Symphony" she refers to Galatea as her dear comrade who supports her.
  • Her Chaldea self also seems to have buried the hatchet with Altria Caster as well. Upon clearing Avalon le Fae, Altria is quick to offer her friendship to Baobhan Sith, and if her Valentine's scene is any indication where she got her help in making chocolate she reciprocated.
  • She's also struck a friendship with Saber Medusa; in exchange for making shoes for Euryale and Stheno, Medusa helps Baobhan Sith to fiddle with the simulation room in "Mystic Eyes Symphony" and put the other Servants into situations in which they have to expose their feet so that she can take photos of them.
• Our Vampires Are Different: Vampires in the Nasuverse are fairies of a sort; specifically, True Ancestors are planetary beings on the level of Morgan, but are intended as weapons to cull the human population. They do not need to suck blood for survival, but experience the uncontrollable urge as a side-effect of being modeled after Brunestud, an immortal from the moon. The victims of True Ancestors, and their victims, resemble more typical undead vampires. This is not the case for the Baobhan Sith, an unrelated and much lower-level fairy which sucks blood for food. In-game, she does not have the Undead trait, but she does have the Fae trait.
• Pet the Dog:
  • She shows a rare selfless and considerate side in her birthday lines. In her first and second Ascensions, she presents a pair of shoes as a gift when she sees that the protagonist only has shoes for work to the point where they make a face in disbelief. Even while undergoing Sanity Slippage in her Third Ascension, she mutters that she has to prepare a gift and frets that she won't be able to make it by the end of the day.
  • In her Valentine's scene, she honestly considers making some form of heels for the Protagonist as a gift... before deciding that doesn't fit her, and instead makes a flying chocolate stake (with Altria Caster's help) that will automatically destroy everyone else's chocolate gifts to you. Even so, the Protagonist notes that this is Tristan giving a heartfelt gift, in her way.
  • A very brief example in the Gloucester auction house. When she realizes the person bidding against her for Muramasa is Altria Caster whom she shared an almost-civil conversation with earlier, she says that she'll let her off just this once. This gets ruined once Murian reveals that the country girl standing in front of her is the Child of Prophecy, but it's still a significant contrast with her Establishing Character Moment a couple scenes ago where she wantonly murdered several faeries just for the fun of it.
• Plot Parallel: Her entire life could be considered one to Cernunnos. Both of them were kindly to fairies, but they were taken advantage of by them and lead to their deaths for said fairies benefit. Both of them also specialize in curses and killing, naturally after they get to a point where they can curse all faekind for the misery caused on them, and enact Disproportionate Retribution in how they don't discriminate between the very few good faeries and the bad ones, all of them must die. No wonder Baobhan Sith is able to awaken Cernunnos, she's the only fairy who could even understand his life and share his level of hatred.
• Politically Incorrect Villain: She's very classist and loves to look down on the poor and lower classes. When she first meets Altria Caster, she mocks the latter for growing up in a backwater village and being "unfashionable."
• The Power of Hate: Invoked in story. Her hatred of the Faeries is so strong and at such an instinctual level that when she falls into the Great Pit, cursing all the faeries and praying to Cernunnos, her absorbtion by him manages to revive his Divine Core, giving him a better Healing Factor that'd require the Black Barrel to destroy and render Altria Caster's sacrifice almost null.
• Really Gets Around: While it doesn't pop up in-story due to her trying to get with Beryl, a line on Barghest's profile notes that Baobhan Sith is more than willing to have one-night stands.
• Royal Brat: She's clearly let her status as Morgan's heir get to her head since she demands that everyone bow down and cater to her, and throws a hell of a fit whenever she doesn't get her way.
• Sanity Slippage:
  • By her Third Ascension, she's started to heavily undergo this. When before she was haughty and more playful, now she's far more solemn and prone to fits of maniacal laughter.
  • In the Lostbelt itself, her sanity takes taking a dive as soon as she loses to Altria Caster for a second time and loses her Gifted Name, which causes faeries to remember her true identity as Baobhan Sith and start insulting her and indirectly Morgan. The fact her soul is rotting from the Fetch magecraft's side-effects and they're beginning to show don't help matters either.
• Shadow Archetype: She has far more in common with her rival Altria Caster than she ever knew. Both were born as kindly fae doomed to Fantastic Racism^*Altria as the Avalon le Fae who is reflexively hated for being destined to end Britain; Baobhan as a vampire which fae found generally disgusting, both were used and abused for their talents^*Altria was treated like literal livestock by her village seeking to use the "Child of Prophecy" fad for money; Baobhan was forced to create zombies because her town's leader found moving corpses fascinating, both were taken in and educated by people who despised the fae^*Altria had Ector and Oberon; Baobhan had Morgan, and both were even accompanied by a person from Pan-Human History^*Altria had the Protagonist; Baobhan had Beryl. The only real difference between the two is that Altria's final caretakers enabled her positive traits, while Baobhan's enabled her negative ones.
• Significant Anagram: The full name of Fetch Failnaught, "Lamenting Music of the Painful Phantasm" uses the same kanji as Tristan's Failnaught in a different order (compare Tristan's 痛哭の幻奏 versus Baobhan Sith's 痛幻の哭奏).
• Slut-Shaming: It goes both ways for her.
  • She mocks Barghest for her many lovers and finds the fact that Barghest legitimately falls in love with them to be even worse.
  • When she gets beaten in Gloucester and has her past as Baobhan Sith revealed to the faeries watching the fight begins mocking her past as a prostitute for Grimalkin and say that Morgan really is out of her mind to appoint someone like Baobhan Sith her heir.
• Smug Snake: Baobhan Sith typically thinks that she's nigh on untouchable due to being Morgan's daughter and the powers gifted to her. This is despite the fact that she's the weakest Tam Lin by a good margin and none of her plans turn out well for her.
• Sore Loser: She does not take her loss in a magecraft duel to Altria Caster gracefully at all for the right of who gets Muramasa at the slave auction, claiming that she only lost due to her powers being sapped by Gloucester's Power Nullifier (ignoring the fact that Altria was under the exact same restriction) and incredulous she could lose to a "country bumpkin".
• Spam Attack: Between Vampirism, Blessed Birth, her deck, and her high-hitcount Noble Phantasm, this Fairy Knight is well set up with two batteries and high natural generation stats.
• Square Race, Round Class: While she does have Failnaught which she does attack with, it is merely part of her overall combat that otherwise relies on magic bullets, acrobatics and growing large spikes from her back. Fetch Failnaught meanwhile is nothing like Failnaught and is more similar to Hassan of Cursed Arm's Zabaniya, where she curses the target to death by first creating a clone from the target's body parts and then killing it. The fact that she was raised to be a witch as Morgan's successor makes it apparent that she is a Caster in the Archer class just so that she can be "Tristan".
• Stripperific: In her Second Ascension, she basically wears a bikini and high heels that resemble barefoot sandals. In her Third and Final Ascensions, she has panties and a strip of cloth over her front that gives way to Navel-Deep Neckline and Sideboob at the same time.
• Stupid Evil: Played with. She almost never does anything selfless for anyone else, focusing almost purely on her own satisfaction with the pure exception being Morgan. Even if her amusement destroys those who would aid Fairy Britain. For example, she kills several chief advisors including a Minister of Justice for fun, aids in harming Woodwose with Beryl which furthers the lie that Morgan wanted him dead and is a huge factor for him turning on her.
• Summon Bigger Fish: When she was thrown into the pit outside Camelot, she made a prayer to Cernunnos to awaken and kill all the fairies. Her sheer hatred of the faeries matched Cernunnos' own, and her absorbtion into him managed to restart his Divine Core, awakening him and making him stronger than a mere shell.
• Token Evil Teammate: Of the three Fairy Knights in the British Lostbelt. Because of this, she is regarded as the most hated of the three Fairy Knights.
• Tragic Dream: Her Third Ascension seems to think that her previous Ascensions were just a dream she was having as she suddenly snaps back into the worn-out, used and abused fairy she actually is.
  Baobhan Sith: …Huh? What was I doing until now…? …I feel, like I was having a happy dream…. Aah… My throat hurts… It hurts. It's like everything from my neck down, was gone… What, am I, becoming?
• Trauma Conga Line: She starts in "Lostbelt No. 6: Fae Round Table Domain, Avalon le Fae" with having almost everything she wants, with only Beryl's love and her mother's attention out of reach. The events of the chapter see her losing everything dear to her as Morgan's actual successor Altria Caster shows up and humiliates her several times in public, she eventually loses her status as one of the Tam Lin, Beryl tricks her into damaging her own soul which leaves her defenseless when Spriggan shows up to take her hostage, and then she has a front row seat to Morgan's brutal death which happened because she couldn't fight back with her daughter's life at stake. Her last scene has her being thrown in the Great Pit like trash as she weeps hysterically, praying for Cernunnos to awaken and destroy everything.
• Troll: If she's not kicking the dog or son of a bitch, she's likely partaking in annoying, messing with or insulting people. She gladly eggs Barghest over how she kills her lovers and loves the idea if Aurora came to Chaldea, likely because she wants to torment or kill her in front of Melusine. Even in her Valentines Scene, she decides to make you chocolate as a gift... before she reveals that it's basically a flying chocolate stake that demolishes any chocolate the Master will receive and that it will follow them no matter where they go for a day before it becomes inert. She insists on taking the Protagonist's bed to have a front row seat.
• Unholy Matrimony: She'd like to be in one with Beryl since she appreciates his taste for murder. Beryl doesn't reciprocate one bit since he's still obsessed with Mash.
• Unknown Rival: She views Altria Caster as her biggest obstacle, as her existence as an Avalon le Fae and essentially Morgan's "daughter" by faerie standards puts her in direct opposition to her own adopted status of Morgan's heir. Plus, she really didn't take her first defeat in a Magecraft duel with her so well. From Altria Caster's point of view, Baobhan Sith is nothing more than a speed-bump on her journey and she lacks a real personal motive to oppose or even dislike her, unlike Morgan or especially Barghest.
• Unskilled, but Strong: Her Patterns of the Age of Gods (the fairy equivalent of Magic Circuits for human mages) are dozens of times stronger than Altria Caster's, but she's only practiced Magecraft in the comfort of her castle, and she isn't naturally skilled in it. When forced into an impromptu duel with Altria Caster in Gloucester, where everyone is Brought Down to Normal, she loses because Altria Caster had to rely on Magecraft for her whole life unlike the other fairies who can perform Mystics naturally, and thus is much more skilled than Tristan, who starts off strong but only quickly exhausts herself once she blows through the magecraft tools she brought with her and can do nothing to fight back.
• Unwitting Instigator of Doom: In several ways.
  • The first is that in her latest incarnation, she was responsible for the Calamity of Resurrection that involved loads of human corpses overflowing and destroying Darlington, and all because Lord Grimalkin was curious about what moving corpses looked like. While she never intended for it to get that bad, as she lays in her bed she wails that Lord Grimalkin forced her to make more.
  • While she was told to be sadistic and cruel by Morgan, her actions also further deteriorate any support Morgan has and can even turn loyal supporters against her. Woodwose for example is partially turned against her because Baobhan Sith had ripped out one of his organs with the Fetch Magecraft Beryl taught her.
  • She aids and allows Beryl to create a strain of the Mors infection that can affect humans, which would further harm Britain if it were unleashed.
  • Finally, she's one to her own doom. While she was taught Fetch Magecraft by Beryl and has gleefully used it, Beryl hid the fact that using it rots the user's soul. By the time she meets Woodwose after his defeat by Percival, she states it makes her feel horrible, and after capturing the protagonist and Altria Caster in the Garden of Lost Will, her fingers have begun falling off along with the rest of her limbs.
• Unwitting Pawn: Beryl used her affection for him to essentially turn her into his personal magecraft attack dog, all the while keeping her in the dark about the soul-poisoning drawback of the magic he taught her.
• Used to Be a Sweet Kid: She used to be a sweet fairy who just wanted to make everyone happy, but the abuse she suffered from fairies in every life and Morgan telling her to live her last life how she wanted turned her into a cold-hearted and sadistic knight.
• Vampiric Draining: Vampirism is one of her skills. Fitting, given her true identity as Baobhan Sith, a Scottish fairy who combines elements of the vampire and the succubus.
• "Well Done, Son" Guy: A gender-inverted example. She seems to place a lot of priority on earning Morgan's affection or making her proud. This is more reflected in her Third Ascension lines.
• Zombie Apocalypse: She ended up causing one in the Calamity of Resurrection, where her lord Grimalkin had her create zombies out of corpses until they overran Darlington and left no other survivors. She is very insistent that it wasn't her fault.
