Kuo-toa

Kuo-toa are a debased monstrous humanoid fish-like race that dwell in the Underdark. They have human-like bodies and fish-like heads.

Society
Kuo-toans maintain friendly relations with drow, their Underdark neighbours. They often raid seaside settlements for human victims.
 * Whip-is the name given to Clerics of Blibdoolpoolp.
 * Monitor-is the name given to those that have trained to fight with nothing but their bodies since birth.

Religion
Most kuo-toas worship the goddess Blibdoolpoolp, though a few remote tribes worship Dagon. Blibdoolpoolp is the focus of the kuo-toas' lives, and even has her own monstrous, deformed kuo-toa breed: the giant kuo-toa leviathan.
