By the way, how would the psychic blast affect the orks?I know they rely on each other for their psychic abilities (the WAAAGH) but is there any possible effects the Emperor's death might have caused them?

Giant party because all the 'umies are uppity? Huge mourning because their greatest single enemy died?

Most of the major craftworlds hang out right near the eye of terror to. Right close to the blast cetnre

The blast center for this psychic hit was in Ultima Segmentum and around Terra so the ones near the Eye of Terror would feel it but survive at least.
