For everyone that likes Warhammer 40k Tabletop and Dawn of War Games or anything to do with Warhammer 40K.
Psi-titans are a specialized and rightly feared class of titan used by the Collegia titanica and developed in secret by the Ordo Sinister.
In place of usual titan configuration, a Psy-titan is equipped with "highly forbidden" Dark Age of Technology-era technology known as the Ciricrux Anima.
These Titan's are manned by damned Alpha-class psykers surgically bound to the cockpit and locked in place against their own will. They are in effect slaved to the Blank Perceptor-intendant, which serves as the princeps/commander of a Psi-titan. This unique setup allows a Psi-Titan to project psychic devastation and phenomena on a truly gargantuan scale.
Some of the psychic powers it can bring forth includes: being able to project massive waves of abject fear, psychokinesis, biomantic leeching of life and even temporal distortion.
However the most feared and dreaded ability of a Warlord Psi-Titan comes from its Sinistramanus Tenebrae, also known as a Psi-Cannon. This relic device allows it to focus the psychic antipathy of the bounded psykers, creating a massive Warp breach similar to that of a vortex weapon.
These titans are truly devastating but rare and are only deployed in the most desperate of situations. So far only 3 deployments or so of Psi-titans have been made. 2 during the Horus Heresy and one during the 13th black crusade.
The only encountered type of Psi-Titan are modified Warlords known as the Warlord sinister class. However other types of Psi-titans are speculated to exist.
This thing sounds like a Demonic Invasion waiting to happen. In those deployments, were they used by loyalists or traitors?
the Ordo Sinister is steadfastly loyal.
I'm imagining the unwilling psyker being a whiny Japanese schoolboy.
get in the fething Titan, Shinji
