Goddess (Three Houses)

The Goddess is a character in the upcoming Fire Emblem Three Houses. She is the "mother of all life" watches over the land of Fódlan in her heavenly kingdom above. She likely controls the afterlife due to her being the "arbiter of every soul."

Church of Seiros
The Goddess gave a revelation to Seiros, the leader of the Church of Seiros - it was a "gift to help guide the lost." The crests the Church of Seiros presumably made in the likeness of The Goddess somehow drive the events of the game.
