Qenepol-luism
(Pronounciaton: qee'-nee-pol-lul-loo)
The Mer religion that worships a host of undersea leviathans who seem to be totally distinct from the Celestials and Infernals. This religion is entirely contained to Merfolk, and even among them, almost entirely contained within the subset of Merfolk who do not interact with land-based cultures. It is unknown if this religion has a formal structure or hierarchy, or if there is any churches within it.
