*{{Main|Ultramar Campaign}}

During the [[Ultramar Campaign]], [[Belisarius Cawl]] and his [[Eldar]] allies managed to revive the wounded [[Ultramarines]] [[Primarch]] [[Roboute Guilliman]] as [[Ultramar]] was besieged by [[Abaddon the Despoiler]]'s [[Chaos Space Marine]] forces. After driving out the Chaos invaders, Guilliman immediately ordered a war council and a debriefing on the situation. Disgusted by what he heard regarding the state of the [[Imperium]], Guilliman entered his private chambers for four days along with [[Marneus Calgar]], [[Tigurius]], [[Voldus]], [[Saint Celestine]], [[Greyfax]], and [[Belisarius Cawl]]. When he emerged, he declared his plan to reach [[Terra]] and manage the situation from there. After a massive parade on [[Macragge]] to unveil the reborn Primarch, Guilliman and his forces left on the ''[[Macragge's Honour]]'' for Terra. Soon enough, word of the Primarch's revival had spread throughout [[Ultima Segmentum]] and reinforcements from the [[Raven Guard]], [[Space Wolves]], [[White Scars]], [[Dark Angels]] and other Chapters such as the [[Mortificators]] and [[Novamarines]]{{Fn|2}} arrived to bolster Guilliman. These are later joined by fresh [[Imperial Guard]] and [[Imperial Navy]], [[Mechanicus]] forces, [[Sisters of Battle]], [[Knight House]]s, and [[Titan Legion]]s. Soon enough, Guilliman had a massive army for his journey to Terra.{{Fn|1a}}

However, the rebirth of the Primarch drew the attention of the [[Chaos Gods]], and the entire [[Warp]] was flung into disarray. The [[Great Game]] escalated in the Warp as hysterical [[Daemon]]ic armies moved on their patron Gods' realms in renewed attacks. The collective result from these disturbances were a series of massive [[Warp Storm]]s across the [[Galaxy]] on a scale not seen since the [[Age of Strife]]. Guilliman's journey to Terra was thus far more difficult than originally expected. The Dark Gods were not the only ones to sense his revival; [[Mortarion]] and [[Magnus]] both felt the resurrection of their brother and begin to plan for the future as well. [[Fulgrim]] possessed the Arch-Consul of Macragge and goaded the brother he had previously wounded 10,000 years ago.{{Fn|1a}}

For the next seven months, Guilliman moved through [[Ultima Segmentum]] and reclaimed worlds under Chaos assault. The surviving Chaos invaders from the [[Ultramar Campaign]] had set their sights on these defenseless worlds. Even worse is the spread of a new blindness-inducing disease that decimated Imperial warriors and civilians alike. It soon became clear that this plague is the product of [[Mortarion]], who has summoned the powers of [[Nurgle]] in its creation. However, the mere presence of Guilliman is able to cure the afflicted, and the Primarch is forced to suspend his trip to Terra to journey across diseased planets and cure their populations. Guilliman's miracles caused further religious hysteria around his return. The Primarch speculated that this was a deliberate plan by the [[Gods of Chaos]] to delay his return to Terra.{{Fn|1b}}

The Red Corsairs launched a boarding operation of the ''Macragge's Honour'' and moved towards the bridge. These attackers were accompanied by Daemons of Tzeentch and Fateweaver himself. Quickly reaching the bridge, Guilliman and Fateweaver began to duel one another. The [[Lord of Change]] revealed that he has been implanting subtle doubt into the mind of Guilliman since he entered the Maelstrom, and now used that doubt as a ritualistic catalyst to finish him. Guilliman was forced to his knees by the negative emotion and became trapped in psychic crystal chains. Fateweaver ordered the Imperials to surrender themselves lest he execute their Primarch. Faced with no other option, the Imperials surrendered and were taken captive. Those that refused were forcibly taken or killed.{{Fn|1b}}

The Imperial captives were moved to a [[Blackstone Fortress]] that Abaddon had gifted to [[Huron Blackheart]]. Fateweaver refused to kill his prisoners, instead wishing to find some use for them in the future. This did not sit well with all the Chaos forces, and [[Skarbrand]] and his [[Khornate]] legions assailed the Fortress in search of the heads of Guilliman and his men. A massive battle erupted between the forces of Tzeentch and Khorne within the Blackstone Fortress.{{Fn|1c}}

As they reached the Webway Portal, Skarbrand himself attacked Guilliman. Guilliman was saved by the efforts of [[Black Templars]] [[Marshal (Black Templars)|Marshal]] [[Amalrich]], who sacrificed himself to drive his sword through the [[Bloodthirster]]'s heart. Guilliman hit this buried blade with his wrist-mounted [[Bolter]], shredding apart the Bloodthirster. Having dealt with Skarebrand, Guilliman and the survivors made it through the Webway Portal.{{Fn|1c}}

Inside the Webway, the Imperials and their Eldar allies came under renewed Chaos Assault, this time from Magnus' [[Thousand Sons]], who had foreseen their escape. Guilliman deduced that Magnus wanted the Eldar to open up the Webway Gate to Terra in order to allow his Thousand Sons to exploit the breach and invade the planet. Not wishing to play along with Magnus' scheme, Guilliman and Veilwalker instead moved for the Webway Portal to [[Luna]]. Despite being hounded by the Thousand Sons at every turn, the Imperials and Eldar eventually reached the portal to Luna.{{Fn|1c}}

On the other side of the Portal, Guilliman and the others arrived in the craters on Luna's surface. However, before Veilwalker could seal the gate, the Thousand Sons burst through, this time accompanied by Magnus himself. A vicious battle erupted as the Imperials and Eldar attempt to stop Magnus from capturing Terra's moon. Brothers once more engaged in a fateful duel as Guilliman battled Magnus. The [[Daemon Primarch]]'s psychic powers overwhelmed Guilliman, but, before he could be defeated, [[Battlefleet Solar]], [[Imperial Fists]], [[Sisters of Silence]], and the [[Adeptus Custodes]] arrived from Terra. The Thousand Sons were being pushed back, and the null-field created by the Silent Sisters negated some of Magnus' powers. This allowed Guilliman to drive his sword through the Daemon Primarch's back. Magnus was forced back through the Webway Portal as Veilwalker closed the gate. With the gate closed, the rest of the Thousand Sons, as well as the Eldar, simply vanished.{{Fn|1c}}

With the battle over, Guilliman and his forces landed at the [[Imperial Palace]]. The Primarch confronted [[Shield-Captain]] [[Adronitus]] and demanded entry past the [[Eternity Gate (Imperial)|Eternity Gate]] so he could confer with the [[Emperor]] himself. Hesitantly, Adronitus agreed, on the condition that Guilliman enter the chamber alone. As Guilliman entered the Emperor's throne room, the Custodes arrested Cypher and his Fallen.{{Fn|1c}}

A day later, Guilliman stepped out from the Eternity Gate. What transpired before the [[Golden Throne]] is not known. However, he gathered all of the [[High Lords of Terra]] and declared himself the new [[Lord Commander of the Imperium]]. The Primarch stated that dark days are ahead, and that he would reorganize the Imperium and its fighting forces in order to confront it and ensure humanity's survival.{{Fn|1c}}
