A charismatic if rather unhinged woman, Sommerkin is the leader of Celestial Gate, a doomsday cult that has grown to rival Hearthkeeper Church in the Abendland countryside.

The Celestial Gate believes that the world is irredeemably corrupt, and the only thing that can be done is to start over in the next one. With the growing threat of the Beast, the cult offers people a way to prepare their souls for the next life. Their current aim, aside from growing their membership, is to depose the current emperor and make Abendland a full theocracy in preparation for the end of the world.
