Celeste made a deal with an eldritch being a long time ago that he would receive eternal protection and life as long as he spread the influence of this being. At the time, he didn't understand what that meant, but over time happily came to accept the responisbility of being the High Priest to the Unknown Void.

He maintains a secluded village deep in a forest, warmly welcoming those who seek them or stumble across them. There's only a few rules to the village, and everyone is free to leave whenever they want.
