Path of Doom

There are few that know of the horrors of the mulitverse, but those who do and decide to fight them off go down a spiral of either death or insanity. However those who have a mind of steel and fury like no other may become avatars of doom. Being on the path of doom means one must devote themselfs to protecting the unable and everyone around them and slaying all those that try to harm other and kill. They are sigified by the mark of the slayer on the back as the orginial slayer the one who all aspire to be when they walk down this path wielded a twin barreled weapon of justice and valued all life and devoted himself to killing demons and devils alike, and the mark symbolizes the weight that they now carry on their back. Now that the orginal slayer had passed his legacy now rests in the path of doom.
