Xalaxian Xenocide

The Xalaxian Xenocide was a joint-xenocidal campaign carried out by both the Bears of the Claw and the Emerald Vanguard Space Marine Chapters against the vile xenos known as the Xalaxians.

History
The Bears of the Claw and their brutal cousins, the Emerald Vanguard, undertake a joint xenocidal campaign against a hitherto unknown xenos known as the Xalaxians upon the Imperial Hive World of Solani. This savage campaign lasts six years, and sees the death of billions of innocents. During the final engagement, the Emerald Vanguard are drawn into a cunning trap by the Xalaxians. With the loss of many of their battle-brothers, the Emerald Vanguard are severely outnumbered. Prepared to face their imminent destruction they boldly prepare to sell their lives dearly. Seeing their plight, the Bears of the Claw, led by Lord Rurik Grimclaw, fight their way through the Xalaxian's lines to save their fellow Astartes Chapter. Leading a corps of Terminator-armoured Battleborn elite, Rurik is slain when he confronts the Xalaxian Overlord. Bolstered by their cousins and emboldened by Lord Rurik's sacrifice, the Emerald Vanguard proceeds to lead the final assault upon the Xalaxian Overlord's position and take the foul creature's head. From then on, the two Chapters forge a strong warrior bond and continue to fight alongside the other in numerous campaigns.
