Truth War

The Truth War is a lamentable time in the history of the Castigators Space Marine Chapter. Sensing troubled times ahead, a lone Inquisitor called upon binding oaths with the Space Marine Chapter, in order to hopefully prevent whatever dark tragedy would befall Mankind. Whatever occurred during this particular campaign has been sealed by an Inquisitorial bull mandate.

History
The Truth War that occurred sometime during the 37th Millennium was a time of great tragedy for the Castigators - a time that stretched the bonds of honour the Chapter enjoys with the Inquisition to breaking point. A time that saw the Castigators were charged with heresy and ended with the death of the legendary Hero-Captain, Lycidius. Inquisitor Reichenbach was an aging member of the Ordo Hereticus. His mind was said by some to be on the edge of sanity, stranding him in a state of constant paranoia. His body had been ritually purified by the Ecclesiarchy and the Inquisition; his mind had been declared untainted by the depredations of Chaos. And yet, Reichenbach was plagued by dark dreams that proclaimed the end of the Imperium was at hand - a dark time that only he could prevent. Reichenbach arrived at the sanctuary sometime during M37.

Invoking binding pacts between the Castigators and the Inquisition, he requested that Chapter Master Orosius provide him with two squads of Space Marines to aid him in a mission of vital importance to the Imperium. Orosius, keen to maintain cordial relationships with the Inquisition, acquiesced. Two full squads of warriors from the Honoured First Company departed with Reichenbach aboard his vessel.
