Legio Lysanda - Notable Campaigns: Battle for Armatura (007.M31) - In the wake of the Battle of Calth, the Word Bearers and the World Eaters Legions launched the Shadow Crusade against the Realm of Ultramar. This campaign saw Titans fighting alongside Space Marine Legions from both sides. During the Battle for Armatura, Legio Audax Warhound-class Titans stalked Legio Lysanda Titans at the behest of the World Eaters.Crusade of Iron (ca. 008-010.M31) - Tetaros Kast, master-princeps of Battlegroup Avalon of the Legio Oberon, was one of the few princeps to fight on Calth and return alive. He brought word to the Forge World of Gantz, homeworld of the Legio Praesagius, of the fate of their fellow Titans and the betrayal that had occurred on Calth. The Traitor Legions were at large among the Five Hundred Worlds of Ultramar, and their very survival was at stake. Princeps Dae Vergos, master-princeps of the Legio Praesagius Warlord-class Titan Pride of Konor, assumed the mantle of princeps ultima and swore vengeance upon the Legio Infernus. She vowed to purge the Five Hundred Worlds of the Traitors' god-engines. Already astropathic cries for aid were reaching Gantz, as the Word Bearers and World Eaters Space Marine Legions, alongside the Legio Infernus, Legio Audax and Legio Mordaxis, spread out from Calth, bringing ruin and despair to the Five Hundred Worlds. Heeding the call of Gantz, Mechanicum fleets gathered, Battle Titans in their holds. Vergos sent emissaries to gather the Legio Oberon and summon the Legio Lysanda back from the Eastern Fringe, while missives were sent to dozens of Knight houses throughout the Five Hundred Worlds, calling in debts of honour. Multiple houses heeded the summons, including House Orhlacc, House Vornherr and House Vyronii. In spite of the betrayal brought to the Five Hundred Worlds, Legio Praesagius gathered its allies and convened its councils of war; the horrors that the Loyalist Titans had faced at Ithraca on Calth would not go unanswered. Princeps Ultima Vergos promised her allies and her fellow Princeps that the Fire Master of the Legio Infernus would face the fury of those still loyal to the Imperium, and wherever the Traitor Titans set foot upon a world, they would find only death. Other Imperial forces soon flocked to their banner and the Legio Praesagius and their allies repeatedly clashed with Horus' forces. This Crusade of Iron would leave worlds burned by its battles and hideous and terrifying weapons were unleashed, such as the Psi-Titans of the Ordo Sinister. While it raged, the Loyalists fought to preserve the Ultramaran way of life, while the Traitors desired only to leave ruin in their wake.Raid on Lysanda (ca. 008.M31) - The Knights of the Traitor House Ærthegn participated in mutiple raids upon macro cargo haulers across Ultramar to cut off Loyalist supply lines and to secure materiel for the Crusade of Iron. The most audacious of these raids remains that of an assault upon a Legio Lysanda "coffin ship." The Traitor Knights overcame the Nobles of House Orhlacc who were tasked with defending the ship and captured those Titans that remained in their cradles.Battle of Last Harbour (009.M31)Battle of Ulixis - The Wyrm's Lair (ca. 009.M31) - Ulixis was used as a staging ground by the Legio Infernus to both harm Ultramar and deal severe damage to the Loyalist forces. Ulixis was one of the principal producers of munitions in Ultramar and, knowing its destruction would deal a severe blow to the Ultramarines' effort to rebuild, Princeps Maximus Horgoth Nyr of the Fire Masters set upon the world. In truth, the Traitor Titan Legion's invasion was the first step towards springing a trap upon the Loyalists. When a combined force of both the Legio Lysanda and the Legio Oberon were drawn to the world, they found its surface devoid of Traitor Titans despite reports to the contrary. It was then the Traitors sprang their trap, seizing control of the planet's orbit and unleashing a fierce orbital bombardment upon the Loyalists on the surface. Though the initial bombardment was devastating, most of the Loyalist forces were driven into the system of caverns beneath the surface, forcing the Fire Masters to commit to a series of running battles beneath Ulixis. For solar days the two Titan forces fought in the dark, their massive weaponry tearing apart the guts of Ulixis. It was within the Wyrms' Lair, a vast cavern littered with the remains of the burrowing creatures that had carved it long ago, that the conflict came to a head, both sides committing their forces in an effort to eradicate the other. As the fighting raged between the two opposing sides, Princeps Raynal Hess in his Warlord Titan Astra Obsurus, leading a Legio Lysanda Myrmidon maniple, charged out to meet Princeps-Maximus Nyr and his Warlorld Titan Mons Ingnum in battle. However, Hess was unaware of Nyr's fellow supporting Fire Masters Titans, which laid in waiting. Their combined volleys crippled the legs of Hess' Titan. However, before the Traitors could strike the killing blow, Hess overloaded his Titan's reactor, and the pitch darkness of the Wyrm's Lair turned to blazing day. When the explosion finally receded, those princeps still in functioning war engines were surprised to see the light remained, for a massive hole had been blown in the cavern ceiling, and a stairway of rubble and broken Titans led up to it. More surprising still was the vox message that came streaming down across all bands -- the Loyalist fleet had returned with reinforcements, and the Traitors were in full retreat. Kast rallied Legio Oberon and the survivors of Legio Lysanda, and pushed the Traitors back. Though Nyr and many of his Titans managed to escape, their hold on Ulixis was broken, and perhaps most crucially of all, the Loyalists had driven the Fire Masters back, disproving the invincibility of their enemies.Dark Waters (ca. 009.M31) - Despite their defeat on Espandor, the Loyalist Titan Legions eroded the strength of their enemies across the Five Hundred Worlds of Ultramar. The Legio Mordaxis, a Traitor Titan Legion that had been transformed by the machinations of the Word Bearers Legion, were charged by their Legio Infernus allies to hunt down and destroy Loyalist Mechanicum forces across the western regions of the Realm of Ultramar. Here, their spies came to the fore and, following reports from Traitors among the Loyalist ranks, the Legio Mordaxis fleet sailed for the remote water world of Zarathusa Secundus. The people of this isolated world existed on floating cities, whose ancient technologies farmed the planet's geothermal wealth. The Loyalists had recently pacified an uprising sparked by Dark Mechanicum cells on the planet, and the aftermath of that war was still evident throughout its shallow seas. The Traitors commenced their attack as the Loyalist forces, commanded by Princeps Tesarius Solomere Krane of the Legio Lysanda, aboard his Reaver-class Titan, Purantum Bellos, awaited extraction upon the principal landmass of Zarathusa, known as the Aquila Atoll. The Traitors seized control of both the planet's orbit and the Loyalist vox-net, masquerading as loyal servants of the Imperium until the trap was sprung. As landers approached the surface of Zarathusa, they revealed themselves not as the intended extraction ships but rather transports carrying the Titans of the Legio Mordaxis. Desperate to deny the atoll to the invaders, Legio Lysanda and the Imperial Knights of House Vornherr scrambled to form an effective defence, aware that retreat was not an option without abandoning those ground forces unable to wade through the seas of Zarathusa; seas that turned black as the battle raged and toxins that had ravaged the Legio Mordaxis polluted the ground they walked upon. Despite their valiant efforts, the Loyalist forces were led into a cunningly laid trap by the Dark Mechanicum allies of the Legio Mordaxis. Much later, the Loyalists would learn the fate of Zarathusa Secundus and its defenders, though not before the corrupted remains of the Purantum Bellos was encountered on Drooth II, along with the blackened Knight armours of dozens of House Vornherr scions, now enslaved to the Legio Mordaxis machine curse.Battle of Drooth II (ca. 009.M31)
