The Legio Praetor is a Loyalist Titan Legion of the Collegia Titanica, one of the military arms of the Adeptus Mechanicus. There is very little information in Imperial records about this obscure Titan Legion, and it is unknown when it was founded and from what Forge World it hails.

  • Sidarius Calvin - Princeps of the Warlord-class Titan Semper Sanctus during the Battle of Macragge. Calvin was supporting the forces defending the Northern Polar Defence Grid, and engaged with a Tyranid construct which would later become known as a Hierophant Bio-Titan. Smaller Tyranid bioforms attempted to scale the Imperial war machine, and although they were targetted by ground-level troops, the sheer amount of bodies and corpses soon clogged the Titan's joints, immobilising it. With his war engine severely damaged and unable to move, Calvin decided to manually overload the Titan's plasma reactor. The resulting explosion obliterated the Hierophant and all other surrounding Tyranids.
