Ten thousand warriors burst from the portal in an instant, only to be met by Gauss arc bombardment more than ten times their number. The reinforcements that followed marched through the dust of their predecessors' disintegration, closing in on the front of the Necrontyr warrior formations through sheer numbers and speed.
