Standing before you is a Warg, Zvolin was his name, blood shed was his game. The warg was a slave to the powers of Sauron, the Black Wizard of Middle Earth, he was controlled and was meant to be the servant of Orcs, to be their stead. Although the young Warg disapproved of this, but he had but no choice to take this job. During the long process of war and death among Middle Earth, But once the war was over, and the  ring had been destroyed, the warg was released from his duties, because the Orcs had been destroyed, and erased from Middle Earth entirely, he of course was saved, because Gandalf the White knew that there was good in his heart, and that if that good was fed, it would grow stronger and stronger, thus his ebony black fur began to turn pure white, white as winter snow and he became the last known Warg in all of Middle Earth, for his other siblings and family had been removed from the world.
