Rhea is a character in Fire Emblem: Three Houses. She is the archbishop and supreme leader of the Church of Seiros. At Garreg Mach Monastery, Rhea can help Byleth increase their rank in Reason, Faith, Brawl, and Swords. She possesses a major Crest of Seiros.


Rhea is what one would expect of a head of a church; benevolent, kind, and compassionate. While she is such to the devout followers of the church and the students and faculty of the Officer's Academy, she is ruthless and dismissive of those who oppose the church. Any who oppose the church are dealt by her righteous vision of justice and even labels their defeats and misfortunes as judgement of the Goddess.

She has a tendency of only giving some form of truth on certain matters, with even people personally close or loyal like Jeralt and Seteth have questioning her actions because of it.
