Psi-Titan

A Psi-Titan is an extremely rare grade of Imperial Battle Titan that is capable of unleashing psychic weaponry, utilising the powers of the Immaterium to defeat its foes. Psi-Titans are only deployed by the unique Titan Legion of the Collegia Titanica known as the Ordo Sinister. Only one class of Psi-Titan is yet known to exist — a modified Warlord-class Titan called the Warlord-Sinister-class Titan. The Warlord-Sinister was only seen in small numbers before the onset of the Horus Heresy. However, rumours persisted at the time of as to the existence of other prototypes and experimental patterns hidden even from the eyes of Imperium’s high officials.
