Matarii

Matarii is a mythical supernatural undead and possibly immortal domestic dylanus that is said to feed on the blood of the living dylanuses. They are very much like the formerly fictional vampires in many ways, although they lack beards, mustaches, and none are fat, unlike some vampires that are fat like they were if they were fat people. They also shapeshift into owls (not bats), brown/black bears (not wolves), and snakes (not rats). It is unknown why we don't see them today, maybe because they never existed or they were killed off to extinction by vampires that outcompeted them and adpated to far worse environmental and economic problems.
