<Snipped quote by The Odeoron>
That sounds a lot like a werewolf. Are you sure you're not from my world?
Werewolves, werebears... krakens... yeah, they all existed in lower dimensions of light. Earth was kindof a little bellow the floating line on holiness, so most cryptids were kinda just liminal in as much as, nobody could quite spot one and those that did, were they weren't all right up there and therefore never trusted by the official powers.
I don't think i am from your realm... But very likely similar entities would exist all across the omniverse in various iterations and forms.
What i described was not a werewolf though...
*Proceeds to snap fingers and produce a vision of the offset triangle or the rim of Purgatory*There... that existed overlayed with Earth but slightly lower in light and order and purity. A place for the evil people to slink into. Not quite hell, but already close to it
