Flayn

Daughter of Seteth, who dotes on her constantly. Having lived a sheltered life, she sometimes appears to lack common sense. She pretends to be Seteth's younger sister. Appears in Fire Emblem: Three Houses. Name: Flayn (Real name: Cethleann) Gender: Female Race: Nabatean (Light Dragon) Birthday: July 12 Age: 1000+ Height: 151cm Relatives: Sothis (Ancestor), Seteth/Cichol (Father), Unnamed Mother (Deceased), Indech (Uncle), Macuil (Uncle), Seiros (Relative) (Cichol is Seteth's real name) Occupation: Unofficial student at the Officers Academy Weapon: Tomes </Personal Information> Flayn appears as a young petite teen girl with long green hair, fair skin and green eyes. She wears a black dress with gold and blue patterns, blue pants and black long boots. Flayn is a sweet, curious and polite girl who speaks with a stiff propriety, but is genuinely friendly and eager to socialize with the students and staff of the Officers Academy. Due to her isolation from the rest of society, she is very curious to learn as much as she can; even something as simple as a fish swimming sideways is enough to get her attention. However, she can take rumors quite seriously, as shown in her supports with Sylvain.

Her interests include making friends and wandering around. She particularly enjoys fishing, even hosting tournaments in the monastery due to having fond memories of fishing with her mother and father. However, she is not a good cook, as everyone, including her father Seteth, leaves the dining hall if she ends up cooking. Only Dimitri enjoys her cooking, but this is due to him lacking his sense of taste.

She detests unnecessary violence, as shown with her supports with Felix. Flayn is a nostalgic person, with fond memories of her mother and childhood. She routinely asks Byleth if they remember when certain things happened, and reminisces about her life before the monastery.

Flayn knows Seteth has good intentions at heart, but dislikes it when he attempts to interfere with her social life, stating that she is old enough to make decisions for herself. She is interested in love and relationships, but Seteth intimidates any student caught making advances towards her, so she attempts to conceal her romantic pursuits. In her ending with Claude, Seteth is kept unaware of their relationship, though in others he does not appear to mind.

Flayn is quite protective of her true identity, as she hastily silenced her uncles Macuil and Indech when they attempted to greet her by her actual name, much to their surprise. She also addresses Seteth as her brother for their own safety most of the time.

Compared to Seteth, Flayn is less composed when the subject about her true identity comes up, as both Linhardt and Claude are able to discern that she is not who she seems. In her supports with Lindhart, he remarks on how she possesses a Major Crest of Cethleann, her affinity for white magic and that Cethleann never had any children. While she is irritated by this, she is unable to convince him otherwise, even accidentally blurting out that she is unmarried before changing it to the past tense. In Claude's case, he suspects that the two actually father and daughter after eavesdropping on one of their arguments. She even tells him that she would acknowledge his words if he found out who she actually was and jokingly teases him when he tells her his theory. Flayn is introduced as Seteth's younger sister. She began living at Garreg Mach Monastery in Imperial Year 1179. She is not a student, though she wants to become one someday. She lives at the monastery, as Seteth is her only family. She is a gentle and gregarious girl who interacts with others openly, but since her curiosity can make her act rashly, she makes Seteth worry a lot.

In reality, Flayn is actually Seteth's daughter. Her mother is buried in the Rhodos Coast. While she claims to lack ties to Cethleann, she is actually the Saint herself. She and her father allied with Seiros during the War of Heroes. Injuries she suffered in the same battle that killed her mother would cause Cethleann to need to enter a dormant state for many years in order to heal. Thus, after the war, she and her father remained in Zanado, isolated from the rest of the world until her father went to the monastery in Imperial Year 1162, leaving her completely alone. Seteth kept her in hiding because he was afraid that others would attempt to use her Crest for nefarious purposes. Having missed out on much of history due to this dormancy and isolation left her surprisingly naive despite how long she has existed.

Flayn greatly enjoys living at the monastery, as it allows her to interact and socialize with others. During the Horsebow Moon, she is suddenly kidnapped, putting Seteth and the Knights of Seiros in high alert. Rumors spread of a Death Knight kidnapping people in the middle of the night. Byleth's house searches the monastery grounds and they discover a secret passage in the knights' quarters, with an unconscious Flayn and another student being held hostage by the Death Knight. They are able to rescue Flayn after the Flame Emperor makes a sudden appearance and orders the Death Knight to retreat.

Relieved that Flayn has been found safe, Seteth initially wants to take her into hiding in order to prevent the situation from happening again. Flayn rejects the idea since it would at most delay the inevitable and she would be much safer in the monastery, surrounded by capable knights, faculty, and the growing students. By her suggestion, she joins Byleth's class as an unofficial student. Seteth agrees as Byleth had proven their merit by rescuing his beloved "sister".

Flayn uses tomes as her weapon.
