The Church of Seiros, also called the Central Church, is a religious organization in Fire Emblem: Three Houses. Its headquarters is Garreg Mach Monastery in the Oghma Mountains of central Fódlan, a neutral territory that is also home to the Officers Academy. The Church's military arm is the Knights of Seiros, and it also has two regional branches: the Eastern Church and the Western Church.
The Church's founder and namesake, Saint Seiros, was said to have been given a revelation, a "gift to help guide the lost", from the Goddess who was watching over Fódlan. Seiros first appeared in the Enbarr region of Fódlan 41 years before the founding of the Adrestian Empire. She performed miracles that inspired the people, and the Church of Seiros was founded to venerate her.
The Adrestian Empire was founded in Imperial Year 1 by Great Emperor Wilhelm I, with Enbarr chosen as its capital due to the presence of Seiros. In Imperial Year 32, Wilhelm I launched the War of Heroes with the goal of conquering all of Fódlan for the Empire. Nemesis, the King of Liberation, united the Empire's opponents under his leadership. Seiros finally slew Nemesis at the Battle of Tailtean in Imperial Year 91, but the war did not end until 98, when Wilhelm I's successor, Lycaon I, succumbed to illness.
In Imperial Year 751, the Holy Kingdom of Faerghus seceded from the Empire after winning the War of the Eagle and Lion. The Church crowned Faerghus's first king, Loog of House Blaiddyd, and granted his nation autonomy. In 801, the region of Leicester rebelled against the Empire, and the Kingdom took the opportunity to occupy the region. In 861, the death of King Klaus I led his three sons to partition the Kingdom into three parts, with each of them ruling a part as an archduke. The death of the archduke of Leicester in 881 gave the Leicester lords the chance to form an alliance rather than accept his heir, sparking the Crescent Moon War. In 901, the war ended with the founding of the Leicester Alliance under the leadership of the influential Duke of Riegan. The constant threat of invasion from countries surrounding the continent eventually forced these three powers to band together under the Church.
In the present era, the three nations exist in relative peace and equilibrium, largely thanks to the mediating influence of the Church. The Church also runs the Officers Academy, which trains the royalty and nobility of Fódlan in the arts of warfare, magic, and leadership.
