Emperor's Spears - Notable Campaigns: Eukari Insurrection (330.M41) - The Imperial world of Eukari was struck by a rebellion led by the forces of Chaos in 330.M41. In response, its planetary governor sent an astropathic plea for aid. As Eukari lay within the region of Elara's Veil, it was within the sphere of responsibility of the Emperor's Spears. The Chapter dispatched a strike force led by Captain Trystance to aid the world. When the Emperor's Spears force arrived, Trystance discovered that the Aurora Chapter was already fighting the rebels. The Aurora Chapter commander berated the Emperor's Spears upon their arrival for failing in their responsibilities to guard the Veil and requiring others to fight their wars for them. This angered Trystance and he ordered the Emperor's Spears' strike force to deploy right into the heart of the rebels' capital city. Though they suffered heavy casualties, over three solar days of fighting, the Emperor's Spears killed the rebel Chaos Lord and thus earned the majority of the glory of the battle for themselves. Trystance then informed the Aurora Chapter's commander that they had had no right to mark the Battle of Eukari as a victory on their war banners, since the Emperor's Spears had actually carried out the operation that resulted in the defeat of the rebels. This led to a squabble between the two Astartes captains, which ended in an honour duel between both Chapter's champions. Yet even this failed to stop the bickering, as the duel proved inconclusive and both Chapters claimed they had won the duel. Eventually a shot rang out and both sides attacked the other in an internecine battle, which resulted in even their orbiting fleets unleashing their weapons upon one another and causing significant damage before a ceasefire was eventually declared to stem the losses. Since both Chapters were Ultramarines successors, the Ultramarines dispatched a group of representatives to finally end the conflict. Upon further review, the Ultramarines ruled in the Aurora Chapter's favour and held that the Emperor's Spears had acted impulsively. The Ultramarines arbitrators also found that the Emperor's Spears had not followed the dictums laid out in the Codex Astartes. As a result, the credit for the victory over the rebels was to be shared equally between the two Chapters. Though the Aurora Chapter was satisfied with this decision, Trystance was infuriated at the outcome, and vowed he would never set foot on the Ultramarines homeworld of Macragge again even if the home of his primarch found itself imperiled. The Emperor's Spears bitterly claimed the outcome was the result of the Ultramarines' cultural inflexibility as a Chapter and their expressed preference for the Aurora Chapter as an organisation that was more compliant with the dictates of the Codex Astartes than the Emperor's Spears. Thereafter, the Emperor's Spears no longer had a close or cordial relationship with their two brother Chapters.Battle of Sythaur (Unknown Date.M41) - It was during this campaign that Sergeant Faelan of the Kavalei tribe, a future hero of the 3rd Warhost, received a grievous wound that disfigured his face.War Against the Exilarchy (ca. 999.M41 - Present) - The birth of the Great Rift cut off the region of Elara's Veil from the wider Imperium, trapping it within the darkness of the Imperium Nihilus. At that time, a great Chaos warhost known as the Exilarchy came into being, comprised mainly of Humans and mutants, but supported by a small number of Heretic Astartes warbands. The true rulers of the Exilarchy were the Chaos Space Marines known as The Pure, the remnants of the Star Scorpions Chapter, who had been declared lost in the Warp. The Pure used the rest of the Exilarchy forces as foot soldiers to further their cause. In the aftermath of the Great Rift's creation, The Pure and the Exilarchy were expelled from their travels through the Warp into Elara's Veil. The worlds of the Veil were part of the Emperor's demesne, but The Pure sought to conquer them and reclaim the region they had once helped to defend in the name of the Dark Gods. This brought them into conflict with their former allies the Emperor's Spears and Celestial Lions Chapters, who were charged with protecting the worlds of Elara's Veil. Due to the sheer numbers of the Exilarchy war host, eventually half of the worlds of Elara's Veil fell to The Pure's control. The Emperor's Spears, the Celestial Lions and the rest of the Adeptus Vaelarii waged a slowly losing campaign against the forces of the Exilarchy. After over a Terran century of warfare, there was no longer any doubt that the Exilarchy and its Heretic Astartes masters had the upper hand.
