Throk is a Water Gargoyle.

These rare creatures are usually found around water pools, They defile the pool and poison it by gurgitating a vile liquid into the water, which dissolves all the inner organs of the creature drinking. They feed off the creatures poisoned by the water, and this specimen was found by Farquarok and Initiated as a Blood Cultists with the promise of raw flesh. Serving nothing but Flesh, Throk the Devourer feels perfectly at home in the cultists. Flesh of the Fallen is summarily devoured..be it friend or foe.

Throk's past is unknown, as many of the Cultists. His future uncertain..but his powers appreciated.
