Legio Invigilata - Notable Campaigns: 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. During the Third War for Armageddon the Legio Invigilata deployed its entire strength of nearly sixty Titans in defence of the world, with the majority of its forces supporting the Imperial Guard regiments, the Astartes of the Salamanders Chapter and the Legio Ignatum in the Hemlock region. One third of the Legion marched to aid the Black Templars Space Marine Chapter and the Imperial Guard regiments of the Armageddon Steel Legion in defending Hive Helsreach, partly as a result of the lobbying of the Black Templar Helsreach Crusade's commander, Reclusiarch Grimaldus. The Legio Invigilata fielded 19 Titans at Helsreach, made up of a full complement of Warhound, Reaver, and Warlord Titans, as well as an Imperator-class Titan under the command of Princeps Majoris Zarha Mancion. This force was instrumental in the defence of Hive Helsreach from the Ork assault, and decimated the Gargants that the Greenskins fielded in their attack. However, the Legio Invigilata battlegroup was pledged to the hive city's defence only by its commanding Princeps' will and the promise she had given to Grimaldus, and after Mancion perished at the hands of the massive Ork Gargant Godbreaker, the Legion's second in command, Princeps Amasat, led what remained of the battlegroup out of the city. Amasat wished to join the rest of his Legion at the River Hemlock, but in fact he would return to Helsreach shortly after abandoning it. The Legio Invigilata battlegroup encountered on its way a sacred weapon of the Adeptus Mechanicus -- Oberon, the Ordinatus Armageddon. This great weapon was forcefully reawakened by the Black Templar Master of the Forge Jurisian, who, acting on Grimaldus' orders, was adamant in his resolve to bring it to Helsreach. The Titan crews were shocked by such blasphemy against the Machine God, but faced with the choice of either dislodging the offender and risking that the relic would be damaged in the process, or escorting him to the hive city, they chose the latter. The Ordinatus had been awakened improperly by the Space Marine, and because of this most of its systems -- including its Void Shield generators -- were inactive, and the Nova Cannon that constituted its main armament could only be made to fire once every twenty minutes. Grimaldus ordered Jurisian to not endanger the Ordinatus, and bade him take only one shot with its great weapon once he reached Helsreach, to be aimed at the Godbreaker. Amasat took his God Machine and two Warhound-class Titans to protect the blessed weapon, and set forth to Helsreach once more. When they arrived, Amasat decided that the best way to protect the Ordinatus was to offer it a clear shot at the Ork Gargant. To this end, Amasat ordered the two smaller Titans to protect the weapon and moved to lure the lumbering xeno war machine out. Amasat succeeded in drawing the colossal Gargant to him, although he died in the process. His sacrifice, however, allowed the Ordinatus Armageddon to obliterate the Godbreaker. Their task complete, the Ordinatus and the Titans finally retreated from Helsreach. Although the battle for the hive city for them was over, the remainder of the Legio Invigilata would continue to fight along the Hemlock River and wherever its advance would lead it.
