After the events that transpired on the world of Avalos, the Kill-Team returned to Watch-Fortress Erioch in order to be debriefed by the Chamber of Vigilance.
After said debriefing, Deathwatch Assault Marine Kyvax Varn was found guilty of using alien technology and was immediately removed from the Kill-Team with his fate unknown to the rest of the Deathwatch brothers.
Furthermore, Deathwatch Apothecary Galmech was required under a different theater of operations within the Jericho Crusade due to the scarcity of Apothecaries.
Both the aforementioned events invariably led to the fracture of the Kill-Team and forced the creation of a new Kill-Team (Excelsior) to be assembled under the watchful guidance of Deathwatch Captain Elias, formerly of the Ultramarines.
Shortly after the acquisition of two new Deathwatch initiates (Brother Kirik and Brother Azazel), Kill-Team Excelsior was petitioned for help by Rogue Trader Diaz Lan, who was presently nominated as the Crusade liaison.
He pleaded his case to the Deathwatch (after he failed the task himself), which was to seek their help in bringing planet Aurum back into the Imperium of Man's fold.
Aurum was classified as a Feral World that once belonged to the Imperium of Man before Mankind lost contact with the Jericho Reach. However and in the current era, they are akin to a pseudo-Barbaric civilization that respects only strength.
Following the briefing about the current events transpiring in Aurum, the Battle Brothers accepted the mission and commenced their journey from Watch-Fortress Erioch to Aurum.
During the voyage (which lasted roughly a month due to the "Horizon's Pride" having to make a detour as to avoid the "Hadex Anomaly"), Brother Azazel spent a considerable amount of time in the company of Diaz Lan and studying his library (and later on, discovering from Diaz Lan that he held a variety of artifacts and forbidden literature), Brother Kavar helped prove the innocence of Kohl Bennex (a crew member of the "Horizon's Pride" that was now imprisoned with murder charges after killing Enginseer Kreth) and Brother Kirik spent his time mostly being vigilant.
After Kohl Bennex had his name cleared, a number of corrupted servitors showed their true colors and tried to kill anyone in their path. With the Deathwatch Brothers springing into action, the threat was quickly contained (shortly after being revealed that the corrupted servitors had been under the care of Enginseer Kreth).
With no further significant events happening onboard the "Horizon's Pride", Kill-Team Excelsior made planet fall on Aurum.
