Luring the greenskins to a promethium refinery, the White Scars prepare to annihilate their foes. But one amongst the sons of Chogoris has a great destiny to fulfil, and Stormseer Kanim must keep him alive, whatever the cost to themselves or their human allies... and whether his brother wishes it or not.
