Fetucristo

An ultimately amorphous being in essence. They have lived as many people, animals, plants, etc over the millennia. They do appear as their own in several distinguishable but interchanging forms. Mostly commonly, they appear to mortals as a smooth charcoal figure of which is human-like with claws on both hands and feet. Their head is the skull of a canis of which on occasion oozes a black, tar-like substance. From it, unattached are sticky tendrils that resemble hair and from their back extends a fleshy tail with another clawed hand attached. Sometimes they are a bare silhouette that grows ever larger, but other times they wear a thick cloak and robes.
