Marines Malevolent - Notable Campaigns: Macharian Crusade (392-399.M41) - The Marines Malevolent deployed the entirety of their Chapter in support of the enormous undertaking known as the Macharian Crusade under the command of one of the Imperium's most notable commanders, Lord Commander Solar Macharius. The Marines Malevolent served alongside the morose Star Phantoms Chapter during many of the campaign's most deadly engagements. But with the death of the Lord Solar in 400.M41, they became swiftly embroiled in the Macharian Heresy -- the civil war and factional division that followed among Macharius' generals and war leaders. The Star Phantoms engaged the Marines Malevolent in a bloody and protracted conflict, resulting in the Marines Malevolent's near destruction at their hands. Though ultimately cleared of heresy, they were censured by the Holy Ordos for their actions.Archimedes Rex Incident (Unknown Date.M41) - A squad of Marines Malevolent under Captain Vinyar faced off with the Salamanders aboard the Adeptus Mechanicus derelict Forge Ship Archimedes Rex. While the Salamanders were there as a rescue force looking for survivors, Sergeant Lorkar's squad of Marines Malevolent arrived to claim salvage to the Astartes power armour and weapons on board, contrary to the traditional agreement the Adeptus Astartes have with the Mechanicus to return such items to their keeping. The Marines Malevolent and Captain Vinyar only relented when threatened with the superior firepower of the Salamanders' strike cruiser Vulkan's Wrath. Later, after Vulkan's Wrath crash-landed on the planet Scoria, Captain Vinyar arrived in time to rescue the survivors of the Salamanders' 3rd Company, but only after the 3rd's captain, N'Keln, agreed to return the salvaged weapons to the Marines Malevolent. Salamanders Chapter Master Tu'Shan later faced down Captain Vinyar on the Salamanders' homeworld of Nocturne after the return of the 3rd Company, accusing Vinyar of shadowing Vulkan's Wrath to extract revenge. Tu'Shan honoured the agreement made by Captain N'Keln, but warned the Marines Malevolent that their arrogance would not be forgotten. It should be noted that although the Marines Malevolent had no legal claim on the Forge Ship's contents, in their defence they had desperate need of it. Many members of the Chapter such as Sergeant Lokar's entire squad still wore Mark VI Corvus Power Armour and used antiquated versions of the Mark Vb Godwyn Pattern Bolter. The Marines Malevolent desperately needed technological upgrades at this time to retain peak combat efficiency.Third War for Armageddon (998.M41) - The Marines Malevolent deployed two full companies to fight in the Third War for Armageddon. During the war, the Marines Malevolent were censured by the Inquisition for launching attacks that cost the lives of thousands of innocent civilians. The Marines Malevolent believed that the end justifies the means and were therefore prepared to conduct war as they saw fit regardless of who was hurt in the crossfire as long as the enemies of the Emperor were defeated. An Ork war party of considerable size had been drawn to the Emperor's Deliverance refugee camp for refugees from Hades Hive. Captain Vinyar waited for the Orks to break through Imperial defences and begin slaughtering the refugees before unleashing his Whirlwind artillery on the camp. Shrapnel shredded the Orks inside and kept them pinned down, which allowed the Marines Malevolent to isolate pockets of Greenskin resistance. After six solar hours of fighting, the Ork warband was utterly destroyed, but at the cost of thousands of refugees' lives. Captain Vineyar of the Marines Malevolent and Chapter Master Tu'Shan of the Salamanders were involved in a tense altercation in the aftermath of this incident. Some sources imply that one participant went so far as to strike the other without a formal duel of honour having been called -- an unusual breach of etiquette in the brotherly ethos of the Adeptus Astartes -- but this is unconfirmed.Duty Unto Death (Unknown Date.M42) - Amidst the shadows of the Imperium Nihilus, a small Imperial fleet found itself beset by a pair of wayward Tyranid Hive Ships. The Imperial flagship, the Terra Nostra, was transporting Primaris Space Marine gene-tech under the protection of Custodian Wardens. Seeing that the fleet would soon be overrun, the guardians' Shield-Captain ordered an emergency teleport to the nearby Death World of Loqe II. Pursued by Tyranid swarms, the Custodian Wardens retreated into the fume-choked volcanic highlands and prepared to defend their precious cargo to the last. Wave after wave of Tyranids surged up the perilous lava-channels, but the Custodians -- cleaving to their oaths of indomitable defence -- repulsed every attack. A solar month later, a relief force of Marines Malevolent arrived in orbit and drove the Hive Ships away with thunderous firepower. On the planet below they found a single living Warden, grievously wounded yet still standing guard over the untouched boon of Primaris technology amidst a fortress of heaped Tyranid corpses.
