Emperor's Peace wrote: Orks don't acknowledge the existence of Khorne or Chaos at all, they believe in their own Gods, Gork/Mork who would give them 'luck' by watching over them in battle, but it's just their superstition in reality the Orks were created by the Old Ones and this is how the come to have some level of psychic abilities in Weirdboyz. Emperor's peace... orks can get corrupted by Khorne, they can also get possessed by the daemons. That's why there is freebooter's orks, who got banned from their clan, because they started worshiping Khorne instead of Gork and Mork. There can be other reason why some orks get banished from their clan.
