The various Titan Legions varied in strength, with some possessing up to 300 god-engines, while the smallest only had a dozen or so. This didn't prevent the different Legios themselves to have varying loyalties to specific Forge Worlds, and continue their own individualistic cultures, doctrines and traditions, hence as we can see in Tempestus, Legio Tempestus and Legio Invicta share different beliefs about the Emperor and the Omnissiah. The Titan Orders were eventually united under a single organization, the Collegia Titanica, because the Fabricator-general of Mars got sick of trying to keep track of every individual order. Secretly, I think Mars was robbing them with exorbitant prices similar to Forge World with their resin models.fortunately, the new Adeptus Titanicus game makes it possible for all of us to buy plastic Titans at a smaller scale and play Adeptus Titanicus games! Woohoo! All hail the Omnissiah! The lesser Forge Worlds that did not possess the necessary templates, resources or expertise to construct and operate their own Titans had to suck up and flatter Mars in order to receive the those stuff to build their own giant robots. Only the greatest Forge Worlds possessed their own Titan Orders, though. Like the Knights (I'm getting a sense of deja vu here), as the crusade expanded they came upon other Titan Orders and Forge Worlds, and incoporated them back into the fold of the Imperium, or specifically Martian rule. Thanks to this, the Titans marched alongside Space Marine Legions, the Solar Auxilia and Imperial Army to obliterate all who would stand in the way of the Great Crusade. The Titan Legions first pledged their loyalty to the Imperium when the Emperor came to Mars to unite Terra and the red planet. Well, they were also rivals that love squabbling with each other like little children - ironic, given their gargantuan sizes. The Legios were formed on Mars during the anarchy of Old Night, consisting of the three oldest houses, the Legio Tempestus (these dudes appeared in the awesome novel Titanicus by Dan Abnett!), Legio Mortis (bastard traitors) and Legio Ignatum. They have been serving Makind since before the Age of Strife, having been created during the Dark Age of Technology.

Embrace the God-Machines of the Imperium! They really deserve their title of "god engines". Bipedal metal giants of walking death that can level entire cities, and protected by thick armor and void shields.

Ever heard of all those awesome Titans almost as big as you, extremely cool-looking and filled to the brim with overwhelming firepower, but with unable to afford even a single of them (probably can afford a Warhound if I sell off all my Knights)? Yup, that's the Titans. The Collegia Titanica is.in a single word, awesome.
