There are dark days in the galaxy.... Kadiya, was destroyed by the rapid onslaught of Chaos. The Great Rift opened, and the demons and horrors of the Long Night gushed from the depths of the warp. But hope is not lost... The long-absent hero has returned, and with him comes the fury of the reincarnated Ultramarines. Robaut Gilliman rebelled and led a crusade, unprecedented since the legendary days of the Emperor, to bring the Imperium out of the darkness. But never before have the Devastating Forces gathered in such numbers, and found a place not desecrated by them. Out of the nightmarish Troubled Stars sprang hordes of the Father of the Plague, Lord Nurgla, and his festering eye crept into Makragg. The insurmountable crusade has come to an end, and Gilliman rushes to Ultramar to clash with the Death Guard.
