Monster Manual

Kuo-toa are fishlike humanoids that once inhabited the shores and islands of the surface world. Long ago humans and their ilk drove the kuo-toa underground, where they dwell in everlasting night. Kuo-toa can no longer abide daylight.

Tormented and Abandoned

At the height of the illithid empire, the mind flayers captured kuo-toa by the thousands and forced them into bondage. The kuo-toa were unable to endure the oppressive mental force the illithids unleashed against them. By the time the mind flayers abandoned them, the prolonged psychic subjugation endured by the kuo-toa had shattered their minds.

The kuo-toa adopted a religious fervor, inventing gods to protect them against threats. Most notable of these threats are the drow, which have slain the kuo-toa on sight since the days when the two races first met.

God Makers

Kuo-toa worship gods of their own creation, but if enough kuo-toa believe that a god is real, the energy of their collective subconscious can cause that god to manifest as a physical entity. The form a kuo-toa god takes depends on the inspiration for its divine image, and is usually random or nonsensical.

One of the most revered gods of the kuo-toa is Blibdoolpoolp the Sea Mother, who takes the form of a female human with a crayfish head, a crayfish’s claws, and an articulated shell covering her shoulders. Blibdoolpoolp was likely invented by a kuo-toa that improved on a broken human statue by adding the limbs and head of a crustacean. In sudden awe of its handiwork, it then named the resulting form a god.

Kuo-toa that cross paths with an aboleth often find themselves worshiping it as a god, unaware to the fact that the aboleth is merely using them for its own nefarious ends.
