Jago Sevatarion - Thramas Crusade: Following the massacre on Isstvan V, the Warmaster sent Night Haunter and his Night Lords Legion on a campaign of genocide against the Imperial strongholds of Heroldar and Thramas in the Aegis Sub-sector of the Eastern Fringes, thus protecting Horus' flank and delaying the Dark Angels Legion from reinforcing the Loyalists. This bitterly contested campaign, known as the Thramas Crusade, dragged on for nearly three standard years. In an attempt to sway his brother Lion El'Jonson to Horus' cause, the Night Haunter left a deep-void beacon in the patrol path of one of the Dark Angels' outrider vessels. The beacon was set to transmit coordinates in advance, so that the two Primarchs could meet and parley on the planet of Tsagualsa. Night Haunter wanted to break his former brother either mentally, physically or both to obtain his objectives.The Primarchs were accompanied by two warriors from their personal Honour Guards to the parley. Sevatar was one of the representatives from the Night Lords along with the Night Haunter's Huscarl, Shang. The Lion arrived to the meeting site with two members of his own Honour Guard, Master Alajos and Paladin Corswain of the Ninth Order. When the Honour Guards had gathered, the pair of Night Lords proceeded to goad and insult their counterparts from the Dark Angels. During their unpleasant conversation, Corsawin noticed Sevatar's gauntlets. The gauntlets were at odds with his midnight armour -- where the war plate was deep, dark blue and marked by streaks of lightning, his gauntlets were painted arterial red. Sevatar explained that it was a mark of shame within the VIII Legion. A warrior's gauntlets were marked this way when he had failed the Primarch gravely enough to warrant death. He would wear the stain of failure on his hands until his execution, at the hour of the Primarch's choosing. This was a Nostraman gang tradition. The hands of traitors and fools were tattooed red by their families to show them as deathmarked. A sign that no gang or family would tolerate grave failure, but that the condemned still had labours to perform before they were allowed to die. Corsawin inquired which one Sevatar was, a traitor or a fool, to which the Night Lords' First Captain replied that he was both. Sevatar did not reveal the circumstances behind the failure that warranted such punishment.The meeting began amicably enough between the two as they conversed with relative civility. This amity lasted only until the Night Haunter slandered El'Jonson, and in return the Lion struck his former brother. This melee further degenerated into an all-out brawl between the two sides. As the Night Haunter strangled the life out of El'Jonson, one of the Dark Angels' Honour Guardsman ran his sword through the Night Haunter's back, saving his Primarch's life. Eventually both Legions sent reinforcements in response to this incident. Each side dragged away their respective Primarchs from the scene of the combat. Both Primarchs survived this brutal confrontation and went on to continue the contest between their Legions for control of the Aegis Sub-sector.When next they fought, the Dark Angels executed a meticulously planned ambush on the Night Lords' fleet while it was in transit across the sub-sector that saw the back of the Night Lords Legion broken and their Primarch mortally wounded after having faced his brother El'Jonson once again in mortal combat. Thanks to the skilled coordination and superb execution by the Lion, the Night Lords fleet was devastated, losing dozens of capital ships and approximately one-quarter of their Legion fleet to the Dark Angels' assault. Unfortunately, the remainder of the Night Lords fleet fled the Dark Angels' wrath, taking their critically wounded Primarch with them before the Lion could finally end his wretched life. This resulted in the death of all but a dozen of the Atramentar and the capture of Sevatar and the remaining survivors. Konrad Curze fled El'Jonson's wrath, evading the Dark Angels for months, stalking the shadows within the bowels of the mighty capital ship. Somehow, the remaining Night Lords managed to affect their escape and fled into the void.
