Originally based on the Forge World of Incaladion, it was subject to constant wars and invasions before it was liberated by the forces of the Great Crusade. Founded by the a Mechanicum Sleeper-Ark during the Age of Strife, the same stable Warp-currents that had succeeded in carrying the Mechanicum to the world were, as time progressed, to bring a host of dark voyagers. As a result, the Incaladion Mechanicum, separated by vast distance from Mars, evolved into a distinctive and highly warlike faction. Waves of xenos invasion spurred unusual avenues of technological development and the creation of vast fortified cities. Throughout this long and savage history, the Legio Fureans formed the principal military force of Incaladion's ruling Archmagos.[2b]
Their more common name the "Tiger Eyes" also stemmed from this early period as a corruption of the name given to them by the feral tribes of the nearby world of Humardu, to whom the Titans truly were divine and terrible beings. Unlike some garrisoning Titan Legions before the Great Crusade, the Legio Fureans did not stand vigil as enforcers for petty empires of the Machine God's servants, but rather fought an unceasing war against a host of foes. For centuries the Legio Fureans unleashed their wrath against invading hordes of Ork marauders and the spiteful raids of Yldari corsairs, scavenging Tarellian war-packs and the colossal viscid horrors of meteor-brought Carnoplasm infestations from the Abyssal Reefs.[2b]
Around fifty years before the Great Crusade would finally reach Incaladion, after a particularly brutal series of incursions and raids, the Taghmata Omnissium - the feudal order upon which the defence and military hierarchy of a Forge World of the Mechanicum is based - finally broke down. In the ensuing strife, the Preceptor-General of Incaladion was assassinated and the Forge World split into warring or isolationist factions, bereft of central control or co-ordination, laying it open to invasion and the devastation which followed. By the time the Great Crusade's advance elements reached Incaladion, it was a global battleground, disported by a dozen different armies; Mechanicum, Renegade and xenos unleashing atomic fire and yet more savage weapons upon each other. During this time, overwhelmed and vastly outnumbered, the Tiger Eyes refused to retreat or retrench, and shattered its blade on foes uncounted until it became only a shadow of its former might.[2b]
After Imperial contact, it fell to the forces of the IV Legion to bear the brunt of the liberation campaign, with such supporting elements of the Legio Mortis and Skitarii. The resulting campaign was to prove the bloodiest in the IV Legion's history to that point, but after two solar years of guerrilla warfare, Incaladion joined the Imperium. After submitting to the Emperor, the Legio Fureans was quickly reconstituted and rearmed, with the deep Titan-forges beneath the planet's surface put to continuous operations to fuel a second birth for the Titan Legion. Travelling beyond Incaladion, the Legio Fureans pursued conflict with an aggressive fervour and tempo of battle seldom matched by any other Titan Legion of the period.[2b] The Legion fought in the Great Crusade in the War in the Shedim Drifts where they were defeated by a massive Eldar flanking attack.
When the Horus Heresy broke out, it was revealed immediately that the Legio Fureans had sided with the Warmaster Horus. It soon joined the new Dark Mechanicum.[2b] During the First Battle of Paramar the Legio Fureans joined with the Alpha Legion in invading the world of Paramar V. However they encountered a force of loyalist Iron Warriors and Legio Gryphonicus, emerging victorious but taking heavy losses. During the Siege of Terra the Legio Fureans were the first Traitor Titans to touch down on the Throneworld after the fall of the Lion's Gate Spaceport to Perturabo.
