Once a sea spirit that just wanted to stay in one place, it pledged it's allegiance to the trickster god Entuu. After being turned into a cave bordering the sea, it discovered that it could magically transport anyone, or anything, that may wander inside of it. To where or when? It still wasn't sure. 

Entuu did grant him another gift. He could communicate with humans. Whether he uses that gift for good or trickery greatly depends on his mood.
