With Guilliman’s return, a great evil returns to spread the corruption of Nurgle. The pieces are laid out for a massive battle in the Ultima Segmentum.

From 8th Edition lore release:

Something terrible came out of of the warp storms as they rolled through the southern reaches of Ultima Segmentum. Where the seeds of corruption had been planted by the Plague That Walks, a new and terrible contamination spread. The diseased dead rose to claim the living. Previously, the walking corpses could be destroyed, but now doing so only released hordes of Nurglings that writhed impossibly out of the withered flesh of the fallen. Hive worlds were toppled, and as the Blackness descended, there was no escape. In the horrific ruins, Cults of Corruption slithered out of hiding, summoning forth further aid from the Realm of Chaos.

So did systems fall, creating the Scourge Stars – a trio of sickly systems that had fallen to Nurgle. From that power base, the Death Guard and Plague legions issued, systematically reaping planet after planet. On they spread. It was none other than the Daemon Primarch Mortarion that brought the fabled Realm of Ultramar, gem of the whole segmentum, under siege. Plague bombardments rained down, so severe that once gloried hives became pits of agri-worlds became slime-ridden ruins. Chaos was encroaching on many fronts when Roboute Guilliman returned. It was his tactical acumen that first stabilized the many war fronts, and his Spear of Espandor counter-attacking campaign that successfully bought the forces of the Imperium still more time. At the Gates of Parmenio, Roboute Guilliman defeated the Greater Daemon Septicus and his Plague Guard. At Iax, once a glorious garden world, Primarch met Primarch as Guilliman confronted Mortarion, the two brothers fighting to a deadlock before the Chaos forces mysteriously withdrew under cover of a virus bomb.
