Mourarchian is an aquatic being that has taken the shape of a strange, finned horse. It is unknown if it is able to take on other forms but what IS known is that this is a cruel and aggressive being. It will lurk in shallow waters and launch surprise attacks against any living being that comes too close. It will try to drag its prey into the waters it stays in to drown them. If successful, it devours its prey, ignoring only the liver, which floats to the surface as warning to any other beings nearby!
