Flayn

Flayn, or フレン, is a playable character in *Fire Emblem: Three Houses*. She is introduced as the younger sister of Seteth and a resident of Garreg Mach Monastery. However, her true identity is Cethleann, one of the Saints of the Church of Seiros, and a child of the goddess who recently reawakened from a long slumber. Flayn is known for her gentle, gregarious nature and her curiosity, often leading to rash actions that worry Seteth. In gameplay, she is a key support character, excelling in healing magic and providing valuable buffs to her allies. She joins the player's party during the first half of the game, and depending on the chosen route, she can take on various roles, either as an ally or an adversary. Flayn's support relationships, especially with the main character, can grant beneficial boosts to unit abilities. She is a valuable asset for her healing capabilities and rescue magic, making her extremely useful in later parts of the game. She primarily functions as a healer and support unit, and while her physical combat abilities are not as strong, her utility is invaluable to any party.
