The Deep Ones
The dwaves, gnomes, goblins, orcs, and kobolds of Alespra all follow this religion. A polytheistic religion built on the back of The Pantheon. When a demi-god is in hibernation undergound, if it succumbs to corruption, it turns into a deep one. The Deep Ones wander the expansive tunnels underground, spreading their corruption as they go. Many think the Epoch Stone is the remains of a deep one. Corruption in deep ones varies, sometimes to a point that some maintain sanity. The deep ones not lost to insanity, still protect the mortal races.
