The continent is ruled in secret by The mafia. It's leader, known as "The black death", is it's ruthless and mighty leader. nobody on the entire continent know his name or anything about him, except that he is dangerous, fearless, and brutal. He has no mercy, but a well known soft side for dogs and cats, bringing some weirdly charming humanity in this mercyless killer. He never hesitates to make exemples and to eliminate any subordinates or generals that had direspected him or who opposes a threat to him by any means. He is incredibly mistrustfull and will not hesitate to take you down at the first wrong turn. He might seem to be the brute that only thinks after punching, but his spirit and instinct is sharp.
