Legio Interfector - Notable Titans: Hand of Sin (Warmaster Iconoclast-class Titan) - The Hand of Sins depicted above was one of the rare examples of Warmaster Iconoclast-class Titans within the ranks of the Legio Interfector during the Horus Heresy. It is unlikely that the laborious endeavour that is the creation of an Iconoclast Heavy Battle Titan would have been undertaken during the foundation of a younger Titan Legion such as the Legio Interfector. As such, the inclusion of the Hand of Sin amongst the Legio's ranks is a notable one. Analysis of armour debris shed by the Titan following heavy barrages during the subsequent Siege of Attaru's Run, show hallmarks of techwrights associated with Legio Tempestus, while carbon dating places the god-engine's creation at least as early as M27. Extrapolation of such data suggests that the Iconoclast was originally in service to the Legio Tempestus and later gifted to the Legio Interfector. Given that the Loyalist Legio Tempestus on Mars were annihilated during the earliest days of the Schism of Mars, and the Legio's war vaults plundered, it seems likely that the Iconoclast was given to the Legio Interfector as a reward for the Titan Legion's service to the Warmaster Horus.Abhorrent (Warlord-class Titan) - The Abhorrent was once known as the Exemplar, a name gifted to it after its heroic actions during the Great Crusade. When the Legio Interfector was forced to side with the Warmaster Horus, their centuries of valour were cast aside. This very act drove most of the Legio Interfector's Titans mad, twisting their Machine Spirits until they stood as nothing more than pale mockeries of their former selves. Whether out of acceptance or shame for their new path, the Exemplar took a new name as the Legio fought to tear down everything it had once helped to build.Sin of Commission (Warlord-class Titan) - Sin of Commission was one of the Legion's Titans supporting the Iron Warriors and Red Corsairs warbands in their attack on the Forge World Lector's Lowell, which was a stepping stone to the eventual invasion of the Shrine World of Eydolim in the same star system. The presence of Traitor Titans rendered the forgemasters of the world hopeless, as the Skitarii regiments available to them could not possibly fend off the god machines.Fire of Betrayal (Reaver-class Titan) - The sheer ferocity exhibited by the Legio Interfector during the latter years of the Horus Heresy was in stark contrast to their past record. Warhound Titans of the Legion, such as the Face of Betrayal, became infamous for their cruel tactics. Small groups of Interfector Warhounds armed with Inferno Guns would set entire city blocks ablaze in order to divert their foes' attention away from the front line. Such tactics proved effective against the more honourable Titan Legions, who valued the lives of innocents, a virtue the Legio Interfector once possessed themselves.Pax Ascerbus (Reaver-class Titan) - Pax Ascerbus was a corrupted Reaver-class Titan which called itself Teratus and was destroyed by a Legio Fortidus Titan during the Horus Heresy at the Battle of Molech.Purge Master (Reaver-class Titan) - Purge Master was a corrupted Reaver-class Titan that took part in the Battle of Eagle Gate in the Eydolim System in 946.M41.Silence of Death (Reaver-class Titan) - Silence of Death was a Reaver-class Titan which was destroyed by a Loyalist Imperial Knights during the Horus Heresy at the Battle of Molech.Soulmauler (Reaver-class Titan) - Soulmauler was a Reaver-class Titan which was destroyed in the munitorum district outside of Eydol City, the capital of Eydolim, by Space Marines of the Ultramarines' 2nd Company. Several other Titans, amongst them the Purge Master, had been crippled by similar assaults.Bloodweil (Warhound-class Titan) - Bloodweil was a Warhound-class Titan which fought during the Horus Heresy at the Battle of Molech.Lochon (Warhound-class Titan) - Lochon was a Warhound-class Titan which fought during the Horus Heresy at the Battle of Molech.
