Fire Emblem: Three Houses - Church of Seiros

The Church of Seiros

The Church of Seiros is Fodlan’s guiding religious organization headquartered at Garreg Mach Monastery. It was founded by the divine figure Seiros who defeated Nemesis, the Liberator King, during the War of Heroes. Having restored order in Fodlan, the Church of Seiros gave birth to the Adrestian Empire. The Holy Kingdom of Faerghus and the Leicester Alliance became independent territories soon after.
