Chaos is going to be a huge threat to magic based races. Destroying minds since the days of the Horus Heresy.

Tisk tisk.  We don't want to 'destroy' anyone. We should rather like to help everyone if possible. By enlightening them to the bountiful joy that is the worship of the only TRUE gods (not counting that one omnipotent bastard).

Think of all the benefits!
Support from Chaos Forces.
gifts of the flesh.
More and varied magical and psychic powers
Anarchy and Meritocracy instead of whatever oppressive regime controls you now.

It's really great.
