No one has seen him face to face so no one is sure who or what he is.  A Mysterious demonic assassin with the ability to blend, manipulate shadows and cause harm on one's own shadows.   

Little is known on the world above, but down below he was a reluctant evil, didn’t really want to be a demon, just hung out with the wrong crowd. He would be known as an aberrant evil the sort of evil that you can trust but them trusting you is hard earned, honor among thieves and all that. He left the underworld due to a mission from his master to assassinate various figures, some important, some you wouldn’t know if the would of made a change and watch how it effect’s history.

He still does his job but given how wars and the world bickering like little children, he takes his time to take it all in. His work and the study of human nature, it only takes a small push to make the dominoes fall over after all. Now he takes orders from humans of many groups, all they know is he is the best. He takes pride in his work, not known to back stab his employers but is known to make them understand what it means to try to back stab him. (you can imagine)

The Voice has a cold,deep baritone voice. With a hint of a accent from another land, from a different time.
