The Legio Ignatum ("Fire Wasps") is a Loyalist Titan Legion of the Collegia Titanica, one of the military arms of the Adeptus Mechanicus. There is very little information in Imperial records about this Titan Legion's founding, though it is believed that they were founded before the Age of the Imperium, during the Age of Strife.
Their motto is Inveniam viam aut faciam which translates from High Gothic as, "I will either find a way or I shall make one." Mars is also the homeworld of two other unnamed Titan Legions whose existence has remained classified.
The Legio Ignatum is one of the oldest and most esteemed Legions within the Collegia Titanica. Originating in the pre-Imperial Age of Strife they were, according to the legends of the Martian Lexmechanics, one of the Triad Ferrum Morgulus -- the three originating Titan Legions created by the besieged Cult Mechanicus during the bloody wars to take back the Red Planet from the degenerate hordes of Cy-Carnivora and mutant scavers that had overwhelmed Mars after the fall.
They had a long-standing rivalry with their fellow members of the Triad Ferrum Morgulus, most notably the Legio Mortis. The Legion fought throughout the Great Crusade and still retains a number of Titans blessed by the Emperor of Mankind Himself at that time.
Later, the Legion fought during the darkest days of the Horus Heresy, defending the Imperial Palace during the Battle of Terra against the insurmountable hordes of daemons and Traitors that the Warmaster Horus had brought to bear.
Innumerable tales of personal heroism and individual sacrifice survive from that time and the Fire Wasps have more than their share. To this day the Legio Ignatum is the only Titan Legion granted the singular honour of guarding the Emperor’s Throne Room, where the Master of Mankind is interred within upon the sacred Golden Throne.
After the siege of the Imperial Palace was broken, the Legio Ignatum went on to fight in most of the major campaigns of the Great Scouring, cleansing Imperial worlds of the Chaos taint of the Traitors. The Legion fought in the mighty conflicts on Paramar V and in the Tallarn System as it strove to drive the Traitor Titan Legions back. In these long and bloody campaigns the Princeps of the Fire Wasps came to know and hate with an abiding passion the Legio Mortis, old rivals which had now turned to dark heresy and foul worship of the Chaos Gods.
It was the Legio Mortis who breached the walls of the Emperor’s Imperial Palace, and it was the Deaths Heads Scout Titans who had terrorised and systematically destroyed the populations of a dozen hive cities on Paramar and Tallarn. The flames of hatred still burn hot and bright in the hearts of the Legio Ignatum -- and one day a reckoning will be made against the remaining Titan Legions amongst the Forces of Chaos.
- Sarosh (Unknown Date.M31) - Sarosh was a planet initially conquered and subdued by the Dark Angels Legion of the 4th Expeditionary Fleet during the Great Crusade. A demi-Legion of Titans from the Fire Wasps was sent to Sarosh to crush any last pockets of resistance, thereby ensuring compliance of the planet.
- Schism of Mars (ca. 007.M31) - When civil war erupted on Mars during the opening days of the Horus Heresy in the Athabasca Valles, the war machines of the Legio Ignatum and the Burning Stars fought in bloody close quarters through the teardrop landforms caused by catastrophic flooding in an earlier, ancient age of the Red Planet. Neither force could gain the advantage, nor could either claim victory, so after a night’s undignified scrapping, both withdrew to lick their wounds.
- The Siege of Calastar (Unknown Date.M31) - In uttermost secret the Legio Ignatum deployed a Maniple of Titans led by the mighty Warlord-class God-engine Scion of Vigilant Light to the Eldar Webway. When Chaos daemons and Traitor Legiones Astartes began to steadily push the Imperials back, the Legio Ignatum covered the retreat of the Imperial forces to the Impossible City, an abandoned Eldar settlement named Calastar that was located within the Webway. Fighting alongside their allies in the Loyalist Mechanicum, the Sisters of Silence and the Legio Custodes, the Legio Ignatum failed to hold the tide of enemies at bay, sacrificing themselves to destroy the enemy Titans. Although the entry to the Webway was saved in extremis by the intervention of the Emperor Himself, all of the Legio Ignatum god-engines were destroyed during the Siege of Calastar, thus heralding the failure of the Imperial Webway Project.
- Battle of Beta-Garmon, "The Titandeath" (006-013.M31) - The Legio Ignatum took part in the long and savage Beta-Garmon campaign, which included hundreds of war zones across dozens of worlds. During this conflict, the Legio Ignatum was supported by the Knights of House Hermetika. 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.
- Third War for Armageddon (998.M41) - Ork Warlord Ghazghkull Mag Uruk Thraka launched a second and even more massive Ork WAAAGH! to conquer the Imperial world of Armageddon in 998.M41, initiating the campaign known as the Third War for Armageddon. As the battles raged on the planet, Ghazghkull unleashed another of his carefully prepared surprises. Incredibly, dozens of Ork Roks (asteroid fortresses) began to descend from orbit. The Roks made landings in the verdant equatorial jungles of the world and across the continents of Armageddon Primus and Secundus. Many were lost to ground fire or accidents but each one that survived became a bastion for the Orks, a rallying point and a ready-made fortress. Besides their formidable armaments, the Roks contained giant teleport arrays. These were employed to teleport down Ork reinforcements, including Gargants and heavy artillery, in an endless stream. Commissar Yarrick personally led attacks by Regiments of Cadian Shock Troops supported by the Titans of the Legio Ignatum and Legio Metalica which destroyed several of these fortresses.
- 13th Black Crusade (999.M41) - When Abaddon the Despoiler and his Forces of Chaos assaulted the world of Cadia during the 13th Black Crusade in 999.M41, the Legio Ignatum was one of the Loyalist Titan Legions of the Collegia Titanica to help in the defence of that beleaguered Imperial Fortress World by providing the Titans of the entire Legion to help throw back the hordes of Chaotic fanatics.
- Siege of Hydra Cordatus (999.M41) - During the 13th Black Crusade, an unnamed Iron Warriors Warsmith laid siege to the world of Hydra Cordatus in an attempt to steal samples of Imperial Fists gene-seed from the Adeptus Mechanicus fortress located on the planet. This Warsmith's warband of Iron Warriors was supported by a battlegroup of Chaos Titans from the Legio Mortis, including the infamous Imperator-class Titan Dies Irae. Three Loyalist Warlords, two Reavers and two Warhound-class Titans drawn from the Legio Ignatum were stationed on the planet to provide support for the Mechanicus garrison forces. The Imperial defenders fought back bravely and many of the Traitor Titans, including the Dies Irae, were destroyed with the support of the Legio Ignatum 's God-Machines. Unfortunately, the Warsmith eventually conquered the world and captured the gene-seed, which would be used to create new generations of Iron Warriors Chaos Space Marines, a victory for which this Warsmith was raised by the Ruinous Powers to become a Daemon Prince.
- Imperious Prima - A Warmonger-class Titan dating from before the foundation of the Imperium. The Imperious Prima was involved in the valiant defence of the Imperial Palace during the Battle of Terra.
- Magnificum Incendius - The Magnificum Incendius was an Imperator-class Titan of the Legio Ignatum under the command of Princeps Bazzanius that served as part of Terra's defences during the Horus Heresy.
- Imperator Bellum - A Warlord-class Titan that fought on Hydra Cordatus against elements of the Legio Mortis. The Imperator Bellum charged into melee with the Dies Irae and died fighting it, but managed to rip a hole in the armour covering its primary plasma reactor. The Imperator Bellum 's partner, the Clavis Regni, later managed to destroy the enemy Titan by crushing its reactor in its battle claw.
- Clavis Regni - The Clavis Regni was the Warlord-class Titan that succeeded in finally destroying the infamous Imperator-class Titan Dies Irae at the Battle of Hydra Cordatus when it crushed the ancient Traitor Titan's primary plasma reactor with its Battle Claw by exploiting the hole opened earlier in the massive war engine's torso armour. This hole had been created by its partner the Imperator Bellum at the cost of that Titan's life.
- Scion of the Vigilant Light - A Warlord-class Titan under command of Princeps Nishome Alvarek that was deployed to Terra during the Horus Heresy. The Scion of the Vigilant Light was the main Battle Titan deployed by the Legio Ignatium to protect the Imperial Webway Project. The Scion of Vigilant Light was the sole Warlord-class Titan deployed into the tunnels of the Imperial Webway, its immense size calling for it to be disassembled on Terra, transported into the Webway and reassembled there. As with all other Legio Ignatum forces deployed within the Imperial stretch of the Webway, the Scion of Vigilant Light was lost in a most tragic way, betrayed by one of its own kind, the demonically-possessed Reaver-class Titan Black Sky.
- Black Sky - The Black Sky was an esteemed Reaver-class Titan of the Legio Ignatum. At the time of the Horus Heresy, the Titan was commanded by Enkir Morova and selected as part of the Legion's deployment to defend the Emperor's Great Work in the Imperial Webway Project. For five standard years, Black Sky and its fellow engines fought the Eldar and other denizens of the Warp, before the ruptured Webway was swarmed by daemons. It was one of these entities, Drach'nyen, that would take possession of Morova and lead him to kill his own crew. Gaining control of Black Sky through Morova, the daemon caused a last act of ignominy, executing the crippled but victorious Scion of the Vigilant Light before abandoning the Reaver.
- Ascraeus - The Ascraeus was a Warhound-class Scout Titan active during the time of the Great Crusade and the Horus Heresy. It was part of the Legio Ignatium's deployment to the Emperor's Great Work and was destroyed in defence of the Imperial Webway Project.
- Ikarial - The Ikarial was a Warhound-class Scout Titan that was a member of the Legio Ignatium's deployment to protect the Imperial Webway Project. Ikarial was slain covering the final retreat into the Imperial Dungeon beneath the Imperial Palace.
- Ilmarius Novus - The Ilmarius Novus was a Warhound-class Scout Titan that was part of the Legio Ignatum’s deployment to the Imperial Webway, where it was destroyed.
- Fierach - Fierach was the Princeps of the Warlord-class Titan Imperator Bellum that sacrificed itself to destroy the Dies Irae and many of the Legio Mortis elements that assaulted Hydra Cordatus.
- Daekian - Daekian was the Princeps of the Warlord-class Titan Clavis Regni that finally destroyed the Dies Irae and many of the other Legio Mortis elements that assaulted Hydra Cordatus.
- Nishome Alvarek - Nishome was the Princeps of the Warlord-class Titan Scion of the Vigilant Light, one of the very few Titans of the Loyalist Martian Mechanicum deployed to aid the Imperial Webway Project during the dark years of the Horus Heresy. A woman of impeccable standing and stature, Nishome Alvarek was a competent Princeps, ill at ease with the fact that the architecture of the Eldar Webway hindered her from marching against the foes of the Emperor. Standing true to her oaths, Alvarek nevertheless refused to back down or to abandon her command, even when it became evident that the Imperials were losing the battle for control of the Imperial Webway, especially given the fact that the Scion of the Vigilant Light would have to be abandoned, its bulk meaning the Titan was too cumbersome to navigate the rapidly narrowing passsages linking the Webway to the Imperial Dungeon beneath the Imperial Palace. Nishome Alvarek sought to obtain one last great victory before dying, a victory she achieved before being betrayed by one of her own, the daemonically-possessed Reaver-class Titan Black Sky.
- Enkir Morova - Enkir Morova was the Princeps of the Reaver-class Titan Black Sky. A battle-hardened Princeps at the outset of the Horus Heresy, Enkir Morova succumbed to daemonic possession while fighting in the Eldar Webway, defending the Emperor's Great Work. Wearing Morova's flesh, the powerful daemon Drach'nyen unleashed countless atrocities, forcing Morova to slay his own Moderatii before turning Black Sky’s guns on Morova's superior, Nishome Alvarek and the striken Scion of the Vigilant Light.
The Legio Ignatum's colours are red and black; decoration is done in yellow and black, usually flame patterns or stripes.
The Legio Ignatum's badge is a wasp centered on a white delta (triangle), outlined in blue. Behind it is a field of red outlined in yellow. Below the central symbol are rows of skulls.
