Legio Astorum

The Legio Astorum (Warp Runners) are one of the many Loyalist Titan Legions of the Collegia Titanica, the military arm of the Adeptus Mechanicus. The Legio Astorum is one of the oldest Legions, its Forge World being Lucius. This Titan Legion is suspected to have been founded before the Age of the Imperium. The Warp Runners fought throughout the Great Crusade and still retains a number of Titans blessed by the Emperor himself. Later, the Legion fought throughout the darkest days of the Horus Heresy, fighting in numerous engagements including the Battle for Tallarn. The Warp Runners continue to faithfully serve the Emperor and His Imperium.

Great Crusade

 * Kamenka Troika Campaign (Unknown.M31) - Sometime during the middle years of the Great Crusade (the Emperor's great reconquest of the galaxy), the Legio Astorum fought alongside the then-loyal Thousand Sons Legion and a Lifehost of PanPac Eugenians of the Imperial Army . The Emperor had issued the writs of war commanding this combined Imperial task force the difficult task of driving the savage Greenskin menace from the three satellite planets (collectively known as the Kamenka Troika) of the world of Kamenka Ulizarna - a world claimed by the Mechanicum of Mars.  The savagery of that war, the slaughter and relentless, grinding attrition had left tens of thousands dead in its wake. Imperial forces were finally victorious after two years of fighting and earned a score of honours for their war banners.  Victory had been won, but the cost had been high with the loss of nearly an entire Warp Runners' detachment of Titans.  With the successful conclusion of the campaign the Thousand Sons honoured the Legio Astorum by recovering Canis Vertex, the last Legio Astorum Titan to fall.  They repaired and restored the great war machine and then had it transported to their homeworld of Prospero where it was mounted upon the pyramid of the Pyrae Cult.
