Cain Edenson was the Biblical human whom was given the Curse of Cain - where he would be forced to wander the world and those whom attempted to strike him down would be dealt a death seven times as worse, Cain became the first Vampire and attested to his goal of near continuous travel around the world, this is most notable because Vampires are feared by humans hence his looks would scare those that would come to understand his true nature therefore once a scene is created (similar to the Cullens) he moves location.
