He was to be among the [[Space Wolves]] sent to fight {{Fn|1a}} the [[Black Legion]] {{Fn|1h}} on [[Ceretan]], when the [[Chapter]] received a plea for aid from [[Lya'Bru]]. As it seemed certain the Space Wolves would be victorious against the [[Traitor Legion]], Audun was instead assigned a strike force to aid the [[Imperial]] world, from a raid by the [[Orks]] from the ' [[Goffs]] [[Ork Tribe|Tribe]].{{Fn|1a}} The veteran Space Wolf [[Laarsbruk]]{{Fn|1e}} served as his second-in-command,{{Fn|1a}} but when they arrived at Lya'Bru, Audun discovered the [[Xenos]] had launched a full-scale invasion and his strike force was outnumbered.{{Fn|1b}} The Battle Leader still led his forces against the Goffs, but he also attempted to warn the Space Wolves on Ceretan about the invasion. However, Audun discovered that his communications were being blocked.{{Fn|1c}}

The situation worsened, when the [[Battle Leader]] discovered learned that the [[Black Legion]] was fighting beside the invading the [[Goffs]].{{Fn|1d}} This led Audun to suspect a larger plot was at hand, as the [[Black Legion]] were also fighting the [[Space Wolves]] on [[Ceretan]], which he could still not make contact with. Though at [[Laarsbruk]]'s urging, the Battle leader focused on saving [[Lya'Bru]] from the [[Orks]].{{Fn|1e}} Even with a string of victories, however, the Goffs' numbers seemed to be increasing.{{Fn|1f}} In order to reassess their campaign against the Orks, Audun ordered his scattered forces to regroup at a fortress. During their meeting though, a [[Webway Portal]] suddenly opened within the fortress and [[Asuryani]] from the [[Craftworld]] [[Ulthwé]] appeared.{{Fn|1g}}

Though [[Laarsbruk]] advised Audun to attack them, the [[Battle Leader]] refused and instead spoke with the [[Farseer]] leading the [[Ulthwé]]. The [[Asuryani]] leader warned that the [[Black Legion]] sought to destroy both their forces and that the [[Traitor Legion]] was using the [[Goffs]] as puppets in their invasion of [[Lya'Bru]]. The Farseer then offered to enter an alliance with Audun, so that they could defeat both the Black Legion and the [[Orks]]. While Laarsbruk warned Audun , that he could not trust the Asuryani, the Battle Leader still agreed to the [[Xenos]] leader's alliance. He then informed Laarsbruk that it was the [[Emperor]]'s will that they defeat the invaders and that Ulthwé's forces would serve Him in that task.{{Fn|1g}} But when Audun asked why the Ulthwé sought the alliance, the Farseer stated it was because of visions the Xenos leader had received.{{Fn|1h}}

These showed him that the death of the [[Space Wolves]] on [[Lya'Bru]] would effectively breed [[Chaos]]. As it did, the [[Farseer]] informed Audun, when the [[Chapter]]'s forces on [[Ceretan]] were killed, by the [[Black Legion]]. This occurred, after the Space Wolves were tricked into falling into a trap set by the Black Legion's [[Chaos Lord]]{{Fn|1h}} [[Lupus]].{{Fn|1m}} The Traitor Legion was then able to slaughter them and by doing so, Lupus brought glory to the [[Chaos Gods]]. The Farseer, though, promised to lead Audun to Lupus,{{Fn|1h}} who had also been responsible for blocking the Battle Leader's communications,{{Fn|1n}}{{Fn|1o}} so he could avenge their deaths. The [[Battle Leader]] agreed, but would do so only after he had saved Lya'Bru by defeating the Orks. To that end, the two forces then launched an attack that destroyed the [[Goffs]]' weapon and ammo storage areas.{{Fn|1h}} This not only permanently crippled the Orks' offensive, but also caused the Goffs to turn upon themselves and the Black Legion as well.{{Fn|1i}}

Laarsbruk then informed Audun, that an [[Ultramarines]] relief force would soon arrive on [[Lya'Bru]]. The veteran then stated that their alliance with the [[Ulthwé]] [[Farseer]] was now no longer needed, but Audun refused to listen. The [[Battle Leader]] claimed, that he would use whatever weapon he could to seek revenge for their dead on [[Ceretan]]. With the [[Goffs]] now dealt with, Audun led an attack on the [[Black Legion]]'s ships on Lya'Bru, so they could not escape the [[Orks]]' wrath.{{Fn|1i}} After doing so, the Farseer stated he would now lead them to [[Lupus]]' [[Daemon World]],{{Fn|1j}} [[Eradinos]],{{Fn|1k}}, but they had to leave quickly or the [[Chaos Lord]] would elude them. Before they could depart, however, the [[Force Commander|Commander]] of the [[Ultramarines]] relief force confronted Audun and asked why the [[Battle Leader]] he was working with the Ulthwé. This was after the Ultramarines had just been ambushed, and the Commander refused to accept that Audun was using the [[Xenos]] to avenge his slain [[Battle Brother]]s. The Commander then ordered the Ultramarines relief force to attack the Space Wolves, when Audun would not stop defending the Ulthwé. Though the Ultramarines tried to kill both of their forces, the Battle Leader and the Farseer's alliance held and emerged victorious against the Commander's relief force was defeated.{{Fn|1j}}

With the [[GoffsLya'Bru]] and [[Black Legion]]'s invasion largely defeatednow saved, the [[Space Wolves]] and [[Ulthwé]] left [[Lya'Bru]] and invaded [[Lupus]]' [[Daemon World]], [[Eradinos]].{{Fn|1k}} They were unaware however, that the [[Ultramarines]] pursued them and arrived at the Daemon World as well. But when their [[Force Commander|Commander]] saw Audun's alliance fighting the [[Black Legion]], he realized that the [[Battle Leader]]'s cause was just. This led the Commander to order the Ultramarines to join the alliance's battle against the [[Traitor Legion]] as well.{{Fn|1l}} The three forces then succeeded in defeating Lupus' [[Chaos Space Marine]] and [[Daemon]] hordes. When the battle was over,{{Fn|1m}} Audun tracked down the Chaos Lord and personally killed Lupusin a duel. [[Laarsbruk]] then congratulated Audun for completing their mission, avenging their slain [[Battle Brothers]] and for bringing honor to the Space Wolves. And because of the Battle Leader's accomplishments, Laarsbruk was sure that Audun would soon become one of their [[Chapter]]'s [[Wolf Lord]]s.{{Fn|1m}}
