Cerberus

All it took was a few little words, and the world as I knew it was skinned, gutted, rearranged and sewn up again. I had died a quite unfortunate death, you see, but the devil chose me to rekindle the fires burning low. In exchange for the freedom of my family from the Pits, I offered my eternal servitude as the devil's own personal bounty hunter. Now I hunt beasts and burdens alike in the mortal world, in order to keep our realms from colliding.
