Legion History

Notable Campaigns

  • Defence of Tophet VI (Unknown Date.M41) - When the Imperial Forge World of Tophet VI is attacked by an invading force comprised of the hated Iron Warriors Traitor Legion, the Imperium response in force. They send a joint task force consisting of the unforgiving Subjugators Space Marine Chapter alongside the god-engines of Legio Debellator. The battle between the two opposing forces are terrible, as the Iron Warriors are masters at siege-craft, but their forces are further augmented by the surprising appearance of a fallen Warlord-class Titan that spearheads their attacks. Surprisingly, this massive Titan bears the heraldry of the Legio Debellator. To their shame, the loyalist god-engines identify the Warlord Titan as one of their own - the fallen Ecce Bellum - which had been thought lost by the Legio during a previous campaign, when it was sent as part of an Adeptus Mechanicus strike force from the forge world of Agripinaa, into the Eye of Terror. Armed with a pair of Volcano Cannons, the deadly power this formidable god-engine carried, could easily carry the day for its dark masters if the Legio Debellator couldn't counter this dire threat. As the Forces of Chaos assaulted the forge world's primary hive city they managed to breach its walls, however, Ecce Bellum was caught in an ambush by a Legio Debellator Warhound Scout Titan maniple. Despite landing several well-placed shots, the damage was only minimal, and the Warlord Titan quickly gained the upper hand as it crippled both the Argentum Sororis and Ruber Captrix with a deadly psychic attack. However, thanks to the quick actions of Princeps Roan Asander, of the Warhound Titan Ruber Captrix, he was able to contact the fallen Warlord Titan's Princeps Demaratus, reminding him of his duty to the Emperor. Getting through to him for a brief moment, the corrupted Princeps was able prevent the Ecce Bellum from firing its weapons long enough to allow the Ruber Captrix the opportunity fire its Plasma Blastgun directly through the Warlord Titan's faceplate, destroying the larger Titan's command crew. In the wake of the destruction of the Ecce Bellum, the Forces of Chaos were driven back by the Imperial forces and Tophet VI was secured.
