The Quinotaur is tied directly to the birth of the Merovingian royal line of the Franks. King Chlodic's wife was raped by the Quinotaur who then proceeded to give birth to Meroveus, the one who whose line eventually took over rulership. The Quinotaur is a bull from the waist up, and a fish from the waist down. It has five horns on it's head, and no-one is exactly sure were it resides.

Suggested Environments

Any substantial body of water.
