Western Church

The Western Church is a religious organization in Fire Emblem: Three Houses. It is an offshoot of the Church of Seiros, with its headquarters located on the border between the Holy Kingdom of Faerghus and the Adrestian Empire. Although the Western Church still worships the Goddess, it considers the main Church to be heretical and Archbishop Rhea to be an apostate.

History
After years of disputes with the Church of Seiros, the Western Church finally escalated tensions into open conflict by moving to seize a sacred cemetery on the Rhodos Coast. The Church of Seiros dispatched Seteth to reclaim the cemetery, but Flayn insisted on accompanying him with Byleth out of fear for his safety.
