House Mordred - Notable Campaigns: Shadow Crusade (007-008.M31) - Amidst the brutality and horror of the Shadow Crusade, whereupon the World Eaters and Word Bearers Space Marine Legions sought to bring about a dark awakening within the Warp after the creation of the Ruinstorm, Traitor and Loyalist Legions did battle. While the Loyalists reeled from the Calth Atrocity, the butchers of Ithraca, the Legio Suturvora and House Mordred followed the Word Bearers and World Eaters across Ultramar on a trail of blood and flame. Giving themselves wholly to the Warmaster's cause, these Traitor Scions exercised their violence upon planets sworn to the Emperor.Crusade of Iron  (008-010.M31) - In response to the Traitor Legions' assault across the Five Hundred Worlds of Ultramar during the Battle of Calth and the Shadow Crusade, the Loyalists within the region declared the Crusade of Iron. Spearheaded by the Titans of the Legio Praesagius, they led their allies from the Legio Oberon, Legio Lysanda and dozens of Imperial Knight households to isolate the Traitor forces and slaughter them piecemeal. The Legio Audax, alongside their allies from the Legio Infernus, Legio Mordaxis and House Mordred, took part in a number of notable campaigns against the Loyalists during this particular crusade.Ambush at Espandor (ca. 009.M31) - In the wake of the conflict on Ulixis, the Loyalists sought to press the advantage, working to divide the Traitors in order to more efficiently dismantle their strength. When word reached the Legio Praesagius of a gathering invasion intended to seize the Agri-world of Espandor, the Loyalists laid plans to intercept the Traitor efforts, focusing their forces on the Boreaus Agri-sprawl, a heavily developed area containing a maze of feed-towers and macro-granaries that would serve to negate the numerical advantage of the Traitors. Though only a handful of Titans from Legio Praesagius could be mustered, they were supported by several maniples from the Legio Oberon, alongside dedicated companies of both Titan Killer infantry and super-heavy tanks. Amongst their number stood the Psi-Titan Occedentalis-Damysus, the Warlord-Sinister lending its support to Princeps Ultima Dae Vergos' forces for reasons known only to its preceptor-intendant. Having marshalled their forces, the Loyalists hoped to spring a devastating ambush on the approaching Traitor force, consisting of Titans drawn from both the Legio Audax and the Legio Suturvora, with supporting banners from House Mordred. Though Vergos had constructed her plan with meticulous detail, she could not account for the actions of the dark powers to which the Traitors now bowed. The Occedentalis-Damysus, tasked with striking the opening blow against the Traitors, found its talents stifled by the forces the Traitors employed. With the Psi-Titan brought low by packs of Audax Warhounds hiding amongst the very buildings Vergos sought to use against the Traitors, the Loyalists were forced onto the back foot. In an effort to secure victory, Vergos ordered her forces into the city in order to limit the numerical advantage of the Traitors, drawing them into a bitter, close-quarters fight.Second Battle of Paramar V (011.M31) - Paramar V having fallen to the Warmaster Horus' hosts in the opening moves of the Horus Heresy, a mixed force of Loyalists launched an assault against the strategically vital supply nexus with the intent of denying it to the Traitors' war efforts. The Traitors numbered a substantial combined force of House Mordred banners, Legio Fureans and Legio Mortis god-engines that were in the system re-arming and re-supplying after several years of intensive campaigning, and a large presence of Sons of Horus and Word Bearers Astartes. The Loyalists committed a large Titan force drawn from the Legio Atarus, Legio Ignatum and Legio Solaria, with ground assault units of the Blood Angels and White Scars Legions. The Loyalists conducted a series of diversionary attacks across the Paramar System in order to draw forces away from their true target, before conducting a full-scale planetary assault against Paramar V's primary spaceport, capturing it intact and then pressing outwards to begin the destruction of the mass-provender silos sprawling across the plateau beyond. It was soon revealed that the Traitors had seen through the ploy and prepared a large counterattack. Though they inflicted heavy damage on the provender silos before the counterattack hit home, the vast majority of the Loyalist invasion force was surrounded and destroyed without mercy.Battle of Beta-Garmon, "The Titandeath" (006-013.M31) - House Mordred took part in the long and savage Beta-Garmon campaign, which included hundreds of war zones across dozens of worlds. During this conflict, House Mordred provided Knight support to the Legio Suturvora and the Legio Fureans. Even before the greater armies of the Warmaster Horus reached the star cluster, the battle lines had long since been drawn, and fighting had been going on for many Terran years. It was a cauldron of battle that would consume millions of lives before its end and see the demise of entire Titan Legions, earning this campaign the dire moniker of the "Titandeath." The Beta-Garmon Cluster, also known as the gateway to the throneworld of Terra, was the last hurdle that the Warmaster Horus' forces had to overcome before they reached the Imperium's capital world. Heavily fortified by the Loyalists, Beta-Garmon would become one of the greatest and bloodiest battles of the Horus Heresy, as well as one of the longest-lasting.
