The Chaos gods gutter out stars like candles with their retreating screams.

"War is now only ever the sequel to war. War will beget war, and so down through time, generation after generation, and so on thereafter, into a far future where war becomes its own definition, and an end unto itself, where death becomes the reason for war, and war becomes the reason for death, worlds without end.
And in that future, the Old Four will come to delight, for the quick death and sudden end they strove for here, and were denied, will be drawn out forever instead across the infinite architecture of the galaxy in one eternal act of worship to the powers they represent.
For now, though, they scream. They gnash in anguish, thwarted and outplayed; they recoil in frustration, cheated and forsaken; they flail in pain, wounded and obstructed. Their screams of hurt and indignation are so shrill, that stars at the hem of the Milky Way gutter out like candles.
Their anchor is gone. The singular, perfect instrument they invested with their powers is destroyed. Horus is dead, and in the instant of his death, the grip of Chaos Incarnate is broken. The Old Four fall away, suddenly, hysterically, wailing in torment, dragging the warp with them."
