The Apostles were followers of Seiros who specialized in magic and mystic arts - especially rituals that used blood. They were entrusted by her with the task of performing a rite to resurrect the goddess following the completion of Garreg Mach Monastery in Imperial Year 185, using their blood and a powerful item known as the Chalice of Beginnings, but it failed. Burdening themselves with the failure of the Rite of Rising, the Four Apostles disbanded and scattered around southern Fódlan in self-exile.
As part of their self-exile, Timotheos disappeared into a deep forest in Adrestian soil, and later founded a village that would be named after him. Noa would settle along Fódlan's Fangs, eventually founding House Nuvelle. Chevalier would venture further out into the east, eventually founding a village named Kupala within what would eventually be Alliance territory, specifically within Edmund territory. Aubin meanwhile went underground in an unnamed city of shadows, likely Abyss.
