5 Minute History: Collegia Titanica

The Collegia Titanica is the division of the Adeptus Mechanius that commands the Titans - colossal robotic combat walkers which are the most potent ground weapons capable of being deployed by the Imperium. The Collegia was one of the groups of the Adeptus Mechanicus that went over to the Warmaster Horus almost en masse alongside the Legio Cybernetica during the Horus Heresy. The name "Adeptus Titanica" is also used for the corps of Titans fielded by the Mechanicus.
