Isn't he immune to psionic powers? So while he should be able to feel them 'bonking at the gates', so to speak, I don't think the psionic effects of the Warp Storm would do anything to him.

It's really windy, though, and most of the population is turning into horrifying, mutated monstrosities. Oh, and the bolts of lightning can pull things through dimensions, as well as having random psionic effects such as summoning Daemon or exploding shit.
