Seteth

Seteth, from Fire Emblem: Three Houses, is known for his stern demeanor and loyalty to the Church of Seiros. He serves as Archbishop Rhea's right-hand man and is also the older brother (actually, father) of Flayn. Initially skeptical of the new professor Byleth, Seteth gradually acknowledges their abilities after Byleth rescues Flayn. In battle, Seteth is a powerful flying unit proficient in lances, later unlocking the potent 'Swift Strikes' combat art. He's a character shrouded in mystery, hiding his true identity as the saint Cichol and possessing an overprotective nature towards his daughter Flayn. Seteth plays a crucial role in the storyline, potentially becoming a loyal ally or a formidable enemy based on player choices. His story unveils deeper secrets about the game's world, including the goddess Sothis and 'Those Who Slither in the Dark'.
