War of the Beast - Inception of the Deathwatch: Despite the apparent death of The Beast on Ullanor Prime, the ork chanting continued unabated, for weeks. It soon became apparent to Koorland that The Beast was either not dead or another Ork Warlord had assumed control over The Beast's WAAAGH! With their forces nearly bled dry from the desperate fighting on Ullanor, Lord Commander Koorland agreed with the Grand Master of Assassins Vangorich, that a new change of tactics was needed nin order to handle the most dangerous of xenos threats. Koorland proposed the use of small, elite Kill-Teams to eliminate vital strategic assets of the encroaching Greenskins and eventually, The Beast itself.When Koorland proposed that these Kill-Teams would be comprised of Astartes from multiple Adeptus Astartes Chapters, existing purely under his overall command, and would continue to exist even after The Beast was finally defeated, that he met bitter opposition in the form of the High Lord Tobris Ekharth, the Master of the Administratum. Ekarth felt that the Lord Commander's proposal went against the foundations of the Post-Heresy Imperium and the dictates of the Codex Astartes incorporated by Roboute Guilliman. Ecclesiarch Mesring agreed, for he had repeatedly declared such actions as blasphemy in a manner that uneased the other High Lords. In the first Senatorum Election held to vote whether or not to create Lord Commander Koorland's proposed xenos-hunting force, only Drakan Vangorich voted yes while Fabricator-General Kubik and Inquisitorial Representative Veritus abstained.The situation drastically changed when the long-dormant Attack Moon over Terra reactivated. With its subspace gate repaired, a massive force of Ork reinforcements soon swarmed the Attack Moon, as The Beast, discovered to have survived the assault on Ullanor, announced that he would slaughter all of humanity. Though reluctant at first to acquiesce to the Lord Commander's plan to approve the creation of such a force, desperate times called for desperate measures. Therefore, the High Lords of Terra consented to Koorland's proposal. In a second vote, only Ecclesiarch Mesring voted against the proposal, while Kubik and Veritus once again abstained.The original recruits for this newly created elite force were drawn from the survivors of the various Chapters who took part in the initial invasion of The Beast's capital world of Ullanor. These Space Marine re-painted their battle-plate a sombre black, in honour of their fallen brethren that had died during the First Battle of Ullanor. Thus standing in vigil over their fallen brethren, the seeds of the newly dubbed "Deathwatch" were sown. Lord Commander Koorland eventually came to an agreement with the Inquisitorial Representative Wienand, to assuage any doubts held by the rest of the members of the Senatorum Imperialis, that the Deathwatch would fall under the purview of the Inquisition, but an Astartes would ultimately serve as Chapter Master.In their first notable action, a Deathwatch Kill-Team successfully teleported aboard the Attack Moon while the Imperial Navy desperately held the line against an attacking Ork fleet. The Kill-Team was successful in achieving their mission objective by planting Mechanicus beasonce that were reversed-engineered from the Orks' subspace technology. The Imperials' audacious plan was to teleport the Attack Moon out of the Sol System, however,the Adeptus Mechanicus was unable to master the Ork technology, and as a result, when they attempted to teleport the Attack Moon, they inadvertently teleported only half of the massive artificial planetoid, which caused the remaining half to shatter. The debris rained down upon Terra in a hail of debris, with some of the flaming wreckage damaging much of the Imperial Palace. Hundreds of millions of Terra's population died as a result of the ensuing disaster.
