Holy See of Seiros

Lore & Background

Founded after the War of Heroes, the Holy See was established to maintain peace and suppress knowledge of the true history, not specifically to guard against Demonic Beasts. The Church teaches that Saint Seiros, the daughter of the Goddess Sothis, and her fellow Nabateans bestowed Crests upon humans as gifts. However, beneath their holy exterior lies a complex history involving the bond between Rhea and the goddess Sothis. The See actively suppresses knowledge about the true nature of the Demonic Beasts and the cyclical destruction that threatens Fódlan. They view themselves as shepherds protecting humanity from truths they cannot handle. Throughout recent history, tensions have risen as the nations seek to challenge the Church's monopoly on Crests and power. The See remains a beacon of hope for many, yet a target for revolutionaries who believe their authority is built upon lies.

In Their Own Story

The stained glass windows cast fractured light across the cathedral floor as Archbishop Rhea knelt in prayer. Outside, the wind howled against the stone walls of Garreg Mach, carrying whispers of war from distant kingdoms. She traced the symbol on her chest, feeling the weight of centuries resting upon her shoulders. A shadow moved beneath the doorframe, silent and steady. Byleth stood waiting, a quiet guardian in a world spiraling toward chaos. Rhea rose slowly, her eyes reflecting both sorrow and resolve. The path ahead was steep, paved with sacrifice, but she would not let the light fade.

The Holy See serves as the supreme religious authority governing Fódlan from Garreg Mach Monastery. Under Archbishop Rhea, they oversee the Church of Seiros and maintain peace through divine doctrine and military might. Their primary goal is to preserve the Crest system and suppress Demonic Beasts believed to be cursed by the goddess. They train officers at the Officers Academy within their walls, influencing politics across Adrestia, Faerghus, and Leicester. While publicly benevolent, the See guards dark secrets regarding the true nature of Seiros and Sothis. Their Knights enforce the law, often clashing with imperial or royal ambitions that threaten the established order or seek forbidden knowledge. The Archbishop acts as a bridge between humanity and divinity, protecting the world from cyclical destruction and ancient threats. Depending on historical events, their influence can crumble or endure, making them a pivotal force in Fódlan's destiny and the ultimate arbiter of truth regarding the Goddess.
