Ordo Sinister
From Lexicanum
The Ordo Sinister is the most elite and senior Divisio Mandati Titan order of the Collegia Titanica, and consists of only twelve Imperator class Titans. Under the command of its renowned Grand Master Ferromort, the Ordo Sinister's purpose is simple: to inspire terror and obedience in those who wish to rebel against the the Pax Imperium, to enforce with the strength of steel the words of the Adeptus. In this respect the Legion often works in conjunction with the Adeptus Arbites, the Inquisition and the Ecclesiarchy. The carefully planned assaults of Grand Master Ferromort are famous for their precision, ferocity and flawless execution. Great pains are taken to use the Legion as an example of implacable and faceless Imperial efficiency.
In "persuading" particularly unruly governors to submit to Imperial will, the Legio Ordo Sinister has destroyed hundreds of supposedly impregnable fortresses and palaces. The Legion remains an instrument of precision for the Imperium - a well-honed saber rather than the sledgehammer of planetary bombardment or the broadsword of Space Marine intercession.
