House Perdaxia - Notable Campaigns: Invasion of Paramar V (673.006.M31) - Fanatically loyal to the Legio Fureans, House Perdaxia heeded the summons of Archmagos Inar Satarael alongside their Legio when the Traitors invaded Paramar V. During the fighting of the First Battle of Paramar, the Perdaxia Scions sacrificed themselves in their hundreds to defend the Tiger Eyes' Titans, taking dozens of Loyalist Titans down with them.Ruin of Maerdan (008.M31) -  In the third standard year of the Horus Heresy, the Imperial colony world of Maerdan on the edge of the Segmentum Solar became a savagerly contested frontline between the forces of Loyalist and Traitor. Maerdan's cities became flaming ruins and its once-verdant plains were turned to barren wastes, crushed and scoured by the fury of the battle as the Loyalist Titans of the Legio Gryphonicus, Legio Metalica and Legio Destructor clashed with the Traitors of the Legio Mortis, Legio Argentum and Legio Vulturum, along with several Traitor vassal Knight housholds, including House Perdaxia. The Ruin of Maerdan, as the campaign came to be known, was one of the largest Titan battles of the early Horus Heresy, with more than 200 Titans taking to the field against each other. Heavy losses were incurred by both sides and as the war moved on, it left a shattered world behind, with neither Loyalist nor Traitor able to claim true victory. The flames of hatred between the Legio Gryphonicus and Legio Mortis, once staunch allies, burned bright after Maerdan and their enmity would lead them to seek each other out time and again on the fields of battle in the dark years that followed.Battle of Beta-Garmon, "The Titandeath" (006-013.M31) - House Perdaxia took part in the long and savage Beta-Garmon campaign, which included hundreds of war zones across dozens of worlds. During this conflict, House Perdaxia provided Knight support to 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's 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.Scouring of the Ollanz Cluster (012.M31) - As the battle for Beta-Garmon escalated, the unfolding conflict drew increasing numbers of forces into its brutal embrace, but it was not the sole target of the Warmaster's ire. Further afield, smaller detachments sought to conquer star systems deemed important to the Loyalists' war effort with the aim to drain the Imperial forces at Beta-Garmon of supplies and reinforcements. To this end a Traitor force, supported by Titans drawn from Legio Fureans, advanced upon the Ollanz Cluster, intent upon gaining control of the valuable resource worlds within it. Believing the cluster to be devoid of any meaningful resistance, the advancing Traitors were surprised by the sudden appearance of a demi-legio from the Legio Astorum, supported by elements of the Iron Hands Legion. Intending to reinforce Beta-Garmon, the Loyalists had been rearming and refuelling at the Borman System when the Traitors moved upon the Ollanz Cluster. Although outnumbered, the Warp Runners dared not give the invaders unrestricted access to the cluster and moved to oppose their advance. It was upon Borman IV that the turning point of the brief but intense conflict came about. Aware that they were outnumbered and unlikely to triumph in a straight fight, especially against an entrenched enemy, the Loyalists moved to break open their foes' defences with a targeted assault. Marshalling their numbers upon the Yrevendi Desert, the Titans of the Legio Astorum focused their efforts upon a weak point in the Legio Fureans lines. With a Loyalist vanguard luring the Traitors into the Yrevendi Desert thanks to a bold diversionary assault, the Titans of Legio Astorum unleashed their fury upon the Legio Fureans and their vassal Knight houshold, House Perdaxia, hoping to shatter the enemy's strength in a single surprise thrust aimed at devastating the isolated Titan Legion and leaving the overall Traitor strength critically weakened. Such an assault was not without risk, for though the Warp Runners' assault was carefully calculated to ensure the Loyalists outnumbered the pursuing Tiger Eyes, nearly the entire Loyalist strength was committed to this single battle, meaning defeat would effectively hand control of the Ollanz Cluster to the Traitors.Imperial Muster at Beta-Garmon (012-013.M31) - For reasons only understood later in the war, the Ruinstorm that had been invoked by Lorgar, primarch of the Word Bearers, several standard years earlier during the Battle of Calth, began to abate across vast swathes of the galaxy. Loyalist high commanders were able to utilise the potent astropathic relay at Beta-Garmon to contact and recall formerly lost or stranded forces from across the war-torn reaches of the northern Imperium. The Imperial Muster at Beta-Garmon rapidly escalated into the largest gathering of Loyalist might since the early years of the war, a concentration of forces so mighty that the Traitors had to respond in kind. The resulting clash of arms would become known as the "Great Slaughter," a theatre of war of such scale that it would encompass the "Titandeath" and the Sea of Fire campaigns, each major campaigns in their own right. By its end, both sides were so badly bled that their only remaining option for ultimate victory was to force a final, decisive confrontation. As history related, the final battle would be fought at the Siege of Terra, but only after the weighty butcher's bill of the Great Slaughter was paid in full.Second Battle of Nycron City (403.012.M31) - The war of the Horus Heresy finally came to Beta-Garmon II in full force. Having bled the Loyalists in the outer systems, the Warmaster Horus unleashed his maniples of the Legio Fureans, Legio Mortis and Legio Vulpa as well as the Knights of House Perdaxia into the wastes surrounding Nycron City, while his fleet attacked the planet from above and hundreds of Traitor Army regiments stormed the hive cities themselves. In what would become known as the Second Battle of Nycron, Titans broke through the hundred-kilometre deep defences of the PanCrypta Dust Clans, Solar Auxilia and Nemesis Brigades. Legio Astorum maniples led the Loyalist Titans to make a stand in the shadow of Nycron's gate, but ultimately fell, opening the way for the Traitors to flood into the city. With the city under their control, the Traitors moved swiftly to conquer or destroy the rest of Beta-Garmon II.
