[[File:Umbral 51.jpeg|thumb|A [[Knights Cenobium|Cenobium Knight]] stands against the [[Mortus Poisoners]]{{fn|3b}}]]The Battle of Umbral-51 was a sub-campaign of the greater Perditus Theatre. There, the Lion El'Jonson sought to claim the [[Mechanicus]]' relics on [[Perditus]] before the [[Iron Hands]] and [[Death Guard]] did. [[Vendrahel]]'s command, which included the [[Order of the Broken Claws]] and the Legion's 79th [[Space Marine Company|Company]], was sent to claim the relics in '''Umbral-51''''s archaeo-vaults. Despite the Primarch ordering them to stand down, the Iron Hands and Death Guard forces there had refused to stop fighting for the vaults. When his forces landed, however, it was the [[Traitor Legion]] that Vendrahel ordered his forces to attack. The Death Guard then began to overwhelmed, when Umbral 51's [[Mechanicus]] would unleash their [[Imperial Robot]]s in order to kill all the invaders. While this led to the Death Guard's forces shattering, their commander and a few survivors were able to escape and raced to the vault's gates. Shortly afterwards, the Dark Angels were finally able to destroy the Imperial Robots and gave chase after the Traitors.{{Fn|33a}}

Despite the [[Death Guard]]'s head start, the [[Dark Angels]] reached them before they could open the vaults' gates. The two sides were then facing each other, when the [[Paladin (Dark Angels)|Paladin]] [[Ennedreth]] stepped forward and challenged the Death Guard's commander to an honour duel. The [[Centurion (Rank)|Centurion]] [[Kadus Brekkar]] laughed at this and instead used his [[Chem-flamer]] to reduce Ennedreth's body to ash. This enraged Vendrahel and the [[Knights Cenobium|Knight-Preceptor]] led the charge against the Death Guard. As their forces clashed, Brekkar fought Vendrahel for possession of the vaults. In the end, though, the Centurion was killed by the Knight-Preceptor and the Death Guard were destroyed as well. After the battle ended, Vendrahel knelt over Brekkar's body and whispered the names of the Dark Angels who had died. After adhering to his [[Order of the Broken Claws|Order]]'s rites of remembrance, Vendrahel met with '''Umbral'''s [[Mechanicus]]. The [[Tech-Priest]]s then resentfully handed over their relics, after seeing that Vendrahel bore a seal of the pact between their two factions. Afterwards, the Order of the Order of the Broken Claws deemed Umbral-51 to be too dangerous to be left behind. They then planted clusters of [[Tectonic Bomb]]s and ignited them upon leaving. This buried Umbral-51, its Tech-Priests and countless technological artefacts, under tonnes of metal and rock.{{Fn|33a}}
