The Ordo Sinister enforcing the Emperor's will

The Ordo Sinister is an elite Divisio Militaris Titan Legion of the Collegia Titanica, one of the military arms of the Adeptus Mechanicus. There is very little information in official Imperial records about this Titan Legion, including when it was founded or from which Forge World it hails.

Legion HistoryEdit

The Ordo Sinister is an elite special purpose Titan Legion. Comprised solely of a dozen Imperator-class Titans under the command of the renowned Grand Master Ferromort, the purpose of the Ordo Sinister is simple: to inspire terror and obedience in those who are in danger of disrupting the Pax Imperium, to lend the weight of steel to the words of the Mechanicus' ruling Magi. In this respect the Ordo often works in conjunction with the Adeptus Arbites, the Inquisition and the Ecclesiarchy, providing transport and fire support for their ground troops in innumerable short, vicious campaigns. The carefully planned assaults of Grand Master Ferromort are famous for their precision and flawless execution. Great pains are taken to use the Legion as an example of impersonal and faceless Imperial efficiency. In persuading truculent Planetary Governors to submit to the Imperial will the Ordo Sinister has destroyed hundreds of supposedly impregnable fortresses and allegedly unassailable palaces. However, this Titan Legion remains an instrument of precision for the Imperium – a well-honed sabre rather than the sledgehammer of a planetary bombardment or the scalpel of a Space Marine intervention.

Notable CampaignsEdit

  • Retallus IV Campaign (Unknown Date) - On the ancient Ork planet of Retallus IV a WAAAGH! on a colossal scale gathered pace as hundreds of Mekboyz directed the labour of thousands of human slaves in order to raise the towering forms of gigantic Mega Gargants over the Retallus IV's desolate plains, and, inspired by this effort and the promise of war, countless Greenskins rallied to the world in preparation for this crusade. The Imperium was determined to not let this happen, and by the Emperor's direct order, the twelve Imperator-class Titans comprising the entire strength of the Ordo Sinister were dispatched to Retallus alongside other Imperial forces, tasked to smash the WAAAGH! before the green horde spread and drowned the galaxy in blood. Imperial records sadly do not indicate what became of this force, though one can presume that it was successful.
