Fate/Grand Order

Baobhan Sithバーヴァン・シー

Morgan’s adopted daughter and designated successor; a Tam Lin of Faerie Britain

Baobhan Sith is a faerie knight in Fate/Grand Order’s Lostbelt No. 6, Avalon le Fae, introduced under the title Tam Lin Tristan. She is the acknowledged daughter and chosen successor of High Queen Morgan, whose rule shapes Faerie Britain.

Proud, cruel, and theatrically stylish, she uses curses and magecraft rather than the traditional bow of an Archer-class hero. Her fascination with high heels and fashions from Proper Human History gives this feared princess an unexpectedly earnest creative interest.

Biography

The Queen’s Named Knight

In the Britain of the sixth Lostbelt, Baobhan Sith bears the title Tam Lin Tristan, borrowing the name of the Round Table knight from Proper Human History. After hearing Morgan describe the knights, she chose Tristan's name and eventually adopted a string-based fighting style associated with him. She is a distinct faerie, not the human knight Tristan. As Morgan's acknowledged daughter and designated successor, she enjoys a place at court that many other faeries bitterly resent.

A Princess of New Darlington

Morgan's protection gives Baobhan Sith freedom to terrorize others in New Darlington. She works with Beryl Gut in the city's vicious entertainments, including the National Slaughterhouse Theater, and treats the suffering of humans and faeries as amusement. At court, she mocks rivals and flaunts her status, while the other Tam Lin find her behavior increasingly intolerable. Her privilege is real, but it never makes her popular.

The Child of Prophecy

When Artoria Caster and Chaldea become involved in the struggle over Faerie Britain, Baobhan Sith singles out the Child of Prophecy as a rival. She is especially offended by talk that Artoria might have a claim to Morgan's attention. A public confrontation in Gloucester sets their magecraft and reputations against each other, with consequences for Baobhan Sith's pride that extend well beyond the contest.

Fashion from Another World

Beryl's accounts of Proper Human History introduce Baobhan Sith to unfamiliar fashions, above all elaborate high heels. She begins collecting shoes and dreams of designing pairs superior to those made by human craftsmen. For all her cruelty and impatience elsewhere, she approaches footwear with genuine care, aesthetic judgment, and a willingness to work at her craft.

Personality and Motivations

Outwardly, Baobhan Sith is brazen, impulsive, mocking, and hungry for diversion. She enjoys frightening others and turns boredom into an excuse for cruelty. Her self-presentation is deliberately theatrical: she wants to be seen as a beautiful, terrifying princess to whom ordinary rules do not apply.

Her fierce pride centers on her status as Morgan’s daughter. She bristles when the court questions her place or when another faerie appears to challenge it. She can be perceptive about people’s vulnerabilities yet extraordinarily sensitive to humiliation herself; her encounters with Artoria show both sides of that contradiction.

Her sincere enthusiasm for shoes complicates the image of a princess interested only in torment. She can be exacting and absorbed in a design question even while scorning politeness or conventional kindness. That contrast is an established part of her characterization, not evidence that her cruelty is harmless.

Appearance

Baobhan Sith’s principal official appearance features very long, vivid rose-red hair, pale skin, pointed faerie ears, and pale gray eyes. Her first outfit is a dramatic red-and-white ensemble with layered ruffles, a fitted bodice, dark accents, and tall lace-up high-heeled boots. A black pointed, crown-like hair ornament reinforces her royal, gothic silhouette.

Another early ascension outfit exchanges much of the red fabric for a striking black ensemble and a dark flowing mantle while preserving her conspicuous hair, crown-like adornment, and sharp-edged fashion sense. The game also features a later, story-sensitive appearance, which is intentionally not described here.

Abilities

Faerie Magecraft and Territory Creation

One of only two faeries raised as witches in Lostbelt Britain, Baobhan Sith can construct a magical workshop despite having little natural talent for magecraft. She nevertheless uses curses and Gandr projectiles effectively in combat.

Limitations: She has little natural aptitude for magecraft despite her proficiency at building and decorating a workshop.

Fairy Knight (B)

The special protection of a recognized faerie knight enhances her combat capabilities and binds its bearer to the duties and constraints of that position.

Limitations: Its geas forbids attacks against fellow faerie knights and makes killing another bearer fatal to the attacker.

Magic Resistance (EX)

Her class profile assigns her extraordinary resistance to magecraft, a strength shared broadly by Morgan’s faerie knights.

Grimalkin (A)

Grimalkin (A), a skill named for a witch-associated cat faerie, can quiet her footsteps, lighten her movements, and enhance her speed. In gameplay it strengthens her Quick attacks and grants protective effects, although its use also costs other allies HP.

Limitations: Her effective use is still far slower than the extraordinary speed attributed to the arcana's original wielder.

Blessed Scion (EX)

Recognized as Morgan's daughter, she shares a limited form of the queen's royal spatial authority. Her playable Blessed Scion (EX) skill seals enemies' skills and Noble Phantasms for one turn and charges her own Noble Phantasm gauge.

Limitations: The described authority lets her assert herself within Morgan's sphere; it is not unlimited command of the entire kingdom.

Fae Vampirism (A)

Her vampiric faerie ability absorbs life force and magical power. In gameplay, Fae Vampirism (A) drains a single enemy's HP, can reduce that enemy's NP charge, and boosts her own NP gauge.

Fetch Failnaught

Fetch Failnaught is her rank E, Anti-Personnel Noble Phantasm. Using a fragment of an opponent's body, such as hair or a nail, she creates and destroys a duplicate to deliver a curse against the original, even across great distances. Its terminology combines the Scottish 'fetch' with the name of Tristan's bow.

Limitations: It targets one opponent and requires material from that target for the described duplicate-making curse; its combat presentation also follows game mechanics.

Enchanted Strings and Claws

Her combat presentation draws on Tristan-like enchanted strings as well as the extended clawlike attacks associated with her vampiric faerie nature.

Relationships

Morgan

Adoptive mother and queen

Morgan recognizes Baobhan Sith as her daughter, appoints her successor, and teaches her magecraft. Baobhan Sith adores Morgan and fiercely defends her authority.

Beryl Gut

Associate and influence

Beryl introduces her to stories of Proper Human History, sparking her fascination with shoes and modern fashion; he is also involved in New Darlington’s brutal entertainments.

Artoria Caster

Rival and Child of Prophecy

Baobhan Sith treats Artoria as a rival after hearing rumors linking the Child of Prophecy to Morgan. She antagonizes Artoria and challenges her publicly in Gloucester.

Barghest

Fellow Tam Lin

The knight known as Tam Lin Gawain criticizes her behavior and tries to enforce decorum; Baobhan Sith habitually needles her in return.

Mélusine

Fellow Tam Lin

Baobhan Sith is wary of the knight called Tam Lin Lancelot, recognizing how formidable she is despite their shared allegiance to Morgan.

Interesting facts

The game initially displays her name as Tam Lin Tristan, changing it to Baobhan Sith with her second ascension.

That name change is an intentional official reveal mechanic, not evidence of two separate playable characters.

Although her Archer-class profile lists Riding at rank A, the accompanying description says she rides no horse.

Her unusual class skill expresses the faerie’s own swift movement rather than a conventional mounted-knight image.

Traditional Scottish descriptions of a baobhan sith sometimes give the beautiful woman deer-like hooves concealed by a long skirt.

This is a detail of the folklore inspiring her name; it should not be confused with an observed feature of every official FGO costume.

Frequently asked questions

Who is Baobhan Sith in Fate/Grand Order?

Baobhan Sith is an Archer-class faerie knight of the British Lostbelt. Known at first as Tam Lin Tristan, she is High Queen Morgan’s acknowledged daughter and successor.

Is Baobhan Sith the same character as Tristan?

No. Morgan grants her the name and knightly title associated with Tristan of the Round Table, but the faerie Baobhan Sith is a distinct character.

Why does Baobhan Sith collect shoes?

Beryl’s accounts of Proper Human History introduce her to its fashions. High heels become a serious interest, and she wants to design a pair that outclasses human-made footwear.

Does Baobhan Sith use a bow?

Her Archer-class fighting style relies mainly on supernatural strings, claws, magecraft, and a curse-based Noble Phantasm rather than a conventional bow.

Who designed and voiced Baobhan Sith?

Kei Mochizuki illustrated the character, and Azumi Waki provides her Japanese voice in Fate/Grand Order.

Major story spoilers below.

The Faerie Morgan Could Never Save

The later narrative reveals that Baobhan Sith was once a consistently kind, self-sacrificing faerie. Across successive lives, other faeries exploited her generosity until she died, only to be reborn and mistreated again. Morgan, previously known as Aesc, encountered her at the end of those lives. Among countless people she had helped, this dying girl was the one who sincerely thanked her. The bond began long before the feared princess existed. Baobhan Sith's last recollections also include a faerie with whom she could speak normally, though she cannot remember that person's name or the city where they met.

The Last Life in Darlington

As queen, Morgan tried repeatedly to protect Baobhan Sith from the faeries who mistreated her, but each life ended badly. In Darlington, the local lord forced the girl to use a vampiric power she hated; its abuse left the city overrun with the dead. After that life ended, Baobhan Sith's soul was too worn down to be reborn naturally. Morgan revived her, adopted her, and commanded her to be selfish and cruel, believing kindness would only lead to exploitation again. Her favoritism was a desperate attempt to keep one beloved person alive, not a scheme to acquire a useful heir.

Defeats, the Garden, and Beryl

Baobhan Sith's defeats by Artoria and Chaldea, especially the public humiliation in Gloucester, deepen her fixation on proving herself worthy of Morgan. She secretly takes the Garden of Lost Will from the throne and uses it to trap Artoria and Chaldea's Master. Back in New Darlington, her body begins to decay. Beryl suggests either the Garden's curse or a loss of Morgan's magical support may be responsible; he then persuades the nearly helpless girl to hand him the artifact, promising to hide it in the underground sanctuary. The scene does not establish which proposed cause alone explains her decline.

The Coup in Camelot

At Camelot, Spriggan's coup unfolds as the wounded Morgan struggles to reach her throne. Seeing Baobhan Sith's ruined body breaks the queen's concentration, and the hostile faeries seize their chance to attack. They kill Morgan and then turn on Baobhan Sith, whose former royal rank offers no protection. Unable to defend herself, she is mutilated and cast away behind the throne. The reversal is especially bitter: the queen's efforts to save her daughter have ended with both of them destroyed by the same court.

The Great Pit and the Curse Calamity

The dying Baobhan Sith makes her way to the Great Pit, calling out to Cernunnos, the sealed god below. Her suffering and fall become entangled with the curse calamity, for which she serves as a sacrificial catalyst. This is the tragic endpoint of her British Lostbelt story, not a victory or a straightforward redemption. The Archer Servant's later summonable existence does not establish that the version in the Lostbelt survived unharmed.

Separate Chaldea and Summer Appearances

Baobhan Sith also appears as a summonable Servant in Chaldea and in separate event stories. Servant Summer Festival 2023 gives her a comic bookmaking subplot that brings her sharp tongue into a creative setting. These appearances are not a chronological rescue scene following her fall in the Great Pit, and the summer Servant should not be conflated with the original Archer's Lostbelt experience.

Additional story facts

FGO material XIII describes her third ascension as a manifestation tied to the lost protection of Morgan’s magecraft and a shattered sense of self.

The unsettling redesign reflects story events, so treating it as an ordinary costume change would conceal an important part of her tragedy.

Baobhan Sith fears Mélusine's superior strength, yet knows that the knight is emotionally vulnerable through her attachment to Aurora.

Her sense of an advantage over Tam Lin Lancelot comes from knowledge of another person's loyalties, not from being able to defeat the knight in combat.

In FGO material XIII, illustrator Kei Mochizuki says Baobhan Sith’s story proved even more sorrowful than anticipated after the character was designed.

This is a documented production perspective on the character’s tragic presentation rather than a speculative theory about the plot.

Her in-game profile and FGO material XIII describe a horrific side of her shoe collection: she displays severed faerie feet in her bedchamber.

This turns what first appears to be a whimsical taste for high heels into a concrete sign of the violence she inflicts on other faeries.

Spoiler questions

Was Baobhan Sith always cruel?

No. The British Lostbelt story reveals that earlier incarnations were compassionate and repeatedly exploited. Morgan eventually revived and raised her to be cruel in the hope that this would let her survive.

Why did Morgan adopt Baobhan Sith?

Morgan had seen her suffer and die across repeated lives; Baobhan Sith was the one faerie who sincerely thanked her. Adoption was Morgan’s attempt to finally protect her and give her a chance at happiness.

What happens to Baobhan Sith near the end of Avalon le Fae?

After her public defeats, she uses the Garden of Lost Will, suffers severe physical deterioration, and is caught in the coup against Morgan. The court turns on her, and she falls into the Great Pit, where her story becomes entangled with the curse calamity of Cernunnos. There is no conventional rescue at the end of the Lostbelt chapter.

Does her third ascension represent an ordinary new outfit?

No. Official notices warn that it contains Lostbelt No. 6 spoilers, and supplementary character materials connect the form with her deterioration and loss of self.

Does the summonable Baobhan Sith change the Lostbelt ending?

Her presence as a summonable Servant and in later events is a different presentation within Fate/Grand Order. Those appearances do not establish that the British Lostbelt Baobhan Sith survived her original story unscathed.
