Legio Agravides
Collegia Titanica War Glyph



Pre-Imperium (Suspected)




Imperium of Man



The Legio Agravides was a Loyalist Titan Legion of the Collegia Titanica, one of the military arms of the Adeptus Mechanicus. While suspected to have been founded before the Age of the Imperium, during the Age of Strife, it is generally believed that the Legion was destroyed in the opening days of the Schism of Mars in the earliest 31st Millenium during the era known as the Horus Heresy. It is unknown if the Legio Agravides still exists to this day and much of its records and history has been lost.

Legion HistoryEdit

At the outset of the Horus Heresy, Warmaster Horus sent Regulus (an Adeptus Mechanicus representative who had already thrown in his lot with the Warmaster) to Mars to secure the tentative support of the Fabricator-General of the Adeptus Mechanicus, Kelbor-Hal. Regulus convinced the Fabricator-General of the Warmaster's resolve to support increased autonomy for the Mechanicus against the autocratic rule of the Emperor of Mankind. As a show of his appreciation for the Fabricator-General's support, Horus provided information to Kelbor-Hal that allowed the Tech-Priests to open a repository of forbidden knowledge known as the Vaults of Moravec, which the Emperor had ordered sealed.

A Loyalist Titan

When this repository was reopened, there was all manner of forbidden arcane knowledge and weaponry that had obviously been tainted by the corrupting influence of Chaos. Soon the corruption spread throughout the forges and temples across the Red Planet as scrap code -- Chaos-contaminated digital source code that was infected with an arcane computer virus. The scrap code infested the logi-stacks and Cogitator (computer) archives of the Adeptus Mechanicus, causing literal Chaos to emerge in any Cogitator system that was networked to one of its infected counterparts. The Fabricator-General and his Dark Mechanicum allies used this disruption to marshal the strength of their forces, intent on bringing the rule of Mars firmly under their control. Infected by this vicious scrap code, the Titans of Legio Agravides and the Legio Fortidus met their end when their reactors went critical and exploded, destroying their fortresses and eliminating these once-proud Titan Legions from the roster of Loyalist forces. In later years, this night would become known in Mechanicus legends as the Death of Innocence.
