For two centuries, the Legions of the Adeptus Titanicus have served in the armies of the Imperium, but their origins lie long before this time of enlightenment and conquest. Few outside the secretive Martian Priesthood know the truth of how Titans came to be, but fragments of data suggest that, in an age long past, civil war split Mars as debased cults swept across the Red Planet. Only the creation of three Orders of mighty war machines, known as the Triad Ferrum Morgulus, stood against and defeated these hereteks who threatened Mars.
From these three Orders of war engines, the Collegia Titanica was founded, and over the centuries, scores of Titan Legions were formed. Some existed only briefly, wiped out in cataclysmic wars, while others lived on into the Age of the Imperium. When the Emperor came to Mars and the Mechanicum joined His Imperium, the many Legios of Titans embarked on the Great Crusade alongside the Imperial Army and the Legiones Astartes.
As ancient forge worlds were rediscovered and brought into compliance, many were settled by Titan Legions who swore to defend their forge world and its Tech-Priests. The Legios took names that were reflective of their character, or of the world on which they settled, and each swore to defend its forge world and aid the armies of the Imperium against the galaxy’s many threats.
Now, as the Horus Heresy divides the Imperium, many forge worlds and their Titan Legions have chosen to follow the turncoats and rebel against the Emperor. As brother battles brother among the Space Marines, so too do Titan Princeps find themselves turning their devastating weaponry on former brothers in arms…
Each Titan Legion has its own unique heraldry and colour scheme to mark them out in the heat of battle – and each also has its own unique traits, a personality honed over decades or even centuries of battle. In your games of Adeptus Titanicus, you can harness these traits to play your Legio of choice in a unique way – some may allow you to use unique combinations of Titans, add additional equipment to your war engines, or provide different ways to engage your foes. There are two examples in the Adeptus Titanicus rulebook, with more to come in future expansions.
Legio Gryphonicus
Legio Gryphonicus are renowned as glory hunters, prideful and constantly seeking honour in battle. Yet they did not fall to the lures of Chaos. Instead, their pride and lust for glory are channelled into righteous fury against those Titan Legions who have spat upon their oaths. In battle, a War Griffons Titan will target a single enemy engine and vow to bring it down, no matter the cost.
Legio Tempestus
The Stormlords of the Legio Tempestus were one-third of the Triad Ferrum Morgulus, and have one of the longest rolls of honour of any Legio – but this didn’t stop the bulk of the Tempestus Titans turning traitor after decades serving with Horus himself. A garrison left behind on Mars remained loyal, sacrificing themselves in the opening engagements of the Mechanicum civil war. In this, they upheld the paramount tradition of their Legio – finding glory in death.
You’ll find full rules for Legio Gryphonicus and Legio Tempestus in the Adeptus Titanicus Rulebook, which is available to pre-order now in the Adeptus Titanicus Rules Set.
