"The first step in 'The Reshaping' is to unify all life under our control. Then we shall have enough power to end the non-logics of the Immaterium and loosen the grip of the deluded ones.

"The children of the old ones know not of the galaxy as we did. We'll end their the sickening meddlings of the old ones and the galaxy will be in control of the Immortal God-Phaeron, Ramz' Ka!"
