The Legio Kydianos (Death Cry) was originally one of the two Titan Legions of the Collegia Titanica that was sworn to serve the Forge World of Xana II. It eventually became a Traitor Titan Legion of the Dark Mechanicum that repudiated its oaths to the Emperor of Mankind and followed the Warmaster Horus into the service of the Ruinous Powers during the Horus Heresy.

Legion History

The Legio Kydianos was one of two Titan Legions, the other being the Legio Vulturum, created from the Titan forces that served Xana II during the Age of Strife. It was created on the order of the Imperium after Xana II was brought back into contact with the Mechanicum of Mars during the Great Crusade. The Legion's first campaign for the Imperium were the Rangdan Xenocides, where it fought alongside its counterpart.

Notable Campaigns

  • Rangdan Xenocides (ca. 860s-890s.M30) - Following their inclusion in the nascent Imperium of Man, the military forces of Xana II, including the Legio Kydianos, hurled themselves and broke their greater strength in countless battles against the vicious Rangdan xenos on the edge of the Halo Stars near the northern borders of the Imperium, becoming shattered remnants of their former selves, but earning much honour in doing so. More importantly, weapons and arms poured forth from Xana II and were shipped directly to the Segmentum-wide battle lines of the war, providing much needed respite and fresh strength to beleaguered Imperial forces, helping to slowly turn the tide of defeat into first stalemate and eventually victory. It was a victory Xana II was in no small part bled dry to achieve.
