The Uktena is a great horned water serpent as big around as a tree trunk, with a bright blazing crest on its forehead and scales that glow along the edges like some inner fire. Some have described the horns as ram-like and others as moose or stag antlers. It does not use the horns for attack. Uktena fear thunderbirds and will usually retreat to watery depths when one is near. An uktena keeps some treasures in its lair, generally acquired from victims.
