A birthmark in the shape of a wolf is a rare but unmistakable gift from the gods. In ancient Roman times it meant you were destined for great things and might even plant a city. Today religious and spiritual scholars believe that a birthmark in the shape of a wolf means that one is in the bloodline of a werewolf and has retained some of the superhuman strength and senses of that werewolf. Please use these powers for good not for evil! But if you don't believe in 'the gods' it means nothing.
