Beast of Lettir Dallan
A monster of early Irish legend. It has a human head, and a huge bulbous body, not unlike the shape of a smith's bellows. It is the offspring of the daughter of a local priest who was seduced late one night along the lakeside by a monstrous water horse. The Beast of Lettir Dallan later fathered the Ox of Dil along the same lakeside.
