During the apocalypse, someone hid beneath all the chaos in a cave, all alone. He thought he would be safe. This was a large mistake...

This one person, suffered a fate that would level him with an eternal life of pain and sorrow. A crack opened up in the bedrock under him and he was exposed to a rare material known as Void Matter. The Void Matter hit this person in the head, causing a back oozing liquid to start pouring from his eyes. Slowly, it spread around his head, blackening his blood and making him immortal, with a price.

All this person can think about is slaughtering people just to take their blood so he can attempt to cure himself. Nothing has worked... He lives forever in sorrow, roaming your worlds...
