There has been reports of these mysterious beings appearing throughout history.
About this creation
Drawings have been found of large, squid-like creatures found in caves throughout the world.
They supposedly pull their prey to their "mouths" and inject them with venom. This poison wipes the face from their victim's body.
It then twists and contorts their arms and legs into tentacles or some type of additional limbs.
They are then re-released into the world to further spread the infection.
I've taken a much better swing at Black Fantasy with this entry than with my last.
I wouldn't know this was a Mysterion if you didn't tell us... this would have really worked better in the Amalgam category, and still, too many "features" described in the Mysterion category are missing. 2 points (they may have been more if either the main body was either cubic, or coloful).
