When the Great Rift tore open across the galaxy, the Orks saw it as a conduit to even greater conflicts and battles. Ghazghkull’s Great Waaagh! rapidly grew in size and strength with each fresh conquest as the greenskins instinctively mustered for war. The Grand Warlord’s hordes were further swollen as the visions of Ork Weirdboyz compelled their warbands to join the Great Waaagh from light years away. Meanwhile, the Rune Priests of the Space Wolves received visions of their own, foretelling the unification of the greenskin race. Determined to intercede before such an eventuality could befall the Imperium, Logan Grimnar took decisive action, sending his Great Companies across the Sea of Stars in a bid to defeat the Orks before they became unstoppable and finally rid the galaxy of the threat Ghazghkull posed.
