Legio Ignatum - Horus Heresy: This fame, the renown for a loyalty that even the most fearsome of odds could not shake, would seal the fate of the Legio Ignatum. On Mars, a new order was slowly and quietly taking power, the servants of Horus having fully suborned the leadership of the ancient Mechanicum and turned them to the service of the Warmaster.The Legio Mortis and much of the Legio Tempestus had already sworn their loyalty to this new master, leaving only the incorruptible Fire Wasps to stand for the Loyalist cause, unaware of the treachery that surrounded them.What would follow, the Schism of Mars and the destruction of Magma City, are well known to history. The Traitor Titans and their allies turned on the few Loyalists left on Mars, obliterating them from ambush and burning the cities they had protected for centuries, with those of Legio Ignatum fighting to the last in defence of the forge-fanes they were sworn to protect.It is held by the Legio Ignatum as a mark of bitter honour that none of their brethren stationed on Mars would survive the treachery that began the Horus Heresy, each and every one dying in battle against those that had forsaken their oaths to the Omnissiah.Those that survived in distant posts about the Segmentum Solar took heart from this sacrifice, for though the Imperium was now riven by civil war their oaths remained unbroken and their name unsullied.Their course was clear in the face of such perfidy, for oathbreakers could not be allowed to remain unpunished, but with the fall of the grand master of the Legio Ignatum on Mars there remained no single leader to guide the Fire Wasps.Each individual detachment chose for themselves to either hold to their stations or to seek out the Traitors in the name of vengeance. Despite the division within this once mighty Titan Legion, each warrior was determined to fulfil the oaths they had sworn.The traitorous Fabricator-General Kelbor-Hal had removed from Mars the one force he could not turn but had failed to strike a lethal blow. In doing so he had gained only a short respite, for now awakened to fury, the Fire Wasps turned their every thought to revenge, bent their every action to the defeat of those that had forsaken their honour.For those they had once called brother, the warriors of the Legios Mortis and Tempestus, they reserved the deepest hatred, seeing in them a twisted reflection of themselves and taking every chance to meet them in battle to prove once again the strength of their loyalty, a loyalty that would be repeatedly tested until the bitter end of the Horus Heresy.Later, the Legio fought during the darkest days of the Heresy, defending the Imperial Palace during the Siege 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 at the entryway to the Sanctum Imperialis of the Imperial Palace, 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 who had now turned to dark heresy and foul worship of the Chaos Gods.It was the Legio Mortis who had breached the walls of the 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.
