Instances of Khorne-worshipping Orks? Surely with the Orks constant bloodlust and battle-hunger, there would be at least some instances of greenskins abandoning Gork and Mork and turning to Khorne. Is there any records of this, seems like a cool theme to build an army or unit around.

Plus, wouldn't the constant Psychic power used to make their technology work leave them open for Chaos' influence or am I misunderstanding how that works.
