Sea Bishop

Encyclopedia Entry:
A type of mermaid with the lower body of a fish that lives in the ocean. From birth, they are priests who serve the God of the sea, “Poseidon.”   By barrowing the power of Poseidon, they can perform a special ritual in which they remake the body of a man to enable him to live in the sea. Because of that ability, they’re a necessary existence for all the monsters who live in the sea. Their race is the pillar of sea monster society.
