Welzz

Welzz was a large male wels catfish who resided in the underground lake in the lair of the Doomwytes.

Great Doomwyte Korvus Skurr believed the fish to be an oracle, and that his serpent Sicariss was capable of communicating with the creature.

This however, was not the case as Sicariss had been fooling Korvus all along.

Korvus sacrificed creatures captured by the Doomwytes to Welzz, including birds, rats, and toads. Welzz would eat just about anything deposited into his watery domain.

When the adder Baliss invaded the Doomwytes lair searching for water, Welzz's lake was a natural place to find it, and noticing an intruder, Welzz attacked Baliss. This was in vain, as Baliss yanked the catfish out of the water, wrapped his coils around him, and bit him, killing Welzz.
