Narthic was once a man. A good man. One who would try to do the right thing, even if most of the times he wasn't successful. But that usually never stopped him doing(in his mind)what was right. That all changed when he died, turning from a man into something that resembles a monster. When Narthic first arrived in Necromundus, he, like many others had no clue where they were, only the inkling that they were no longer amoung the living. And also like some of the newly dead, he had no real idea of who he was, or what he was like. So to him, he was no longer that person.
