Also considering the Necrons suffer from the Destroyer Curse, which turns them completely insane and hence into (unsurprisingly Destroyers) which is like a cybernetic disease, maybe the Chaos Gods have tried to claw back the iniatative by spreading a virus thoughout the Oligarchi (the name NEEDS to change) which partially turns their bodies to molten metal and causes them to attack their fellows (a bit like the Zombie Plague). Also I have come up with a race for Chaos, the Umbravil who are powerful aliens whose entire culture revolves around daemon symbiosis and attack with warp-enchanced technology and are capable of causing reality tears and transforming planats into daemon worlds.
