Admiral Usurs was a highly influential officer of the Imperial Navy in M33. He later used this influence to form a powerful military bloc comprising his Imperial fleet, as well as armoured and infantry regiments of the Astra Militarum. This increased his power to such an extent that the High Lords of Terra deemed him a threat in 265.M33. However, they were unable to arrest or execute the Admiral without risking a civil war, so the High Lords instead dispatched him on an exploration mission to regions beyond the light of the Astronomican. For the following two decades, Usurs' reports reached Terra, detailing the conquering of new systems for the glory of the Emperor, then the communiqués ceased. Contact with the systems mentioned in Usurs’ reports was never attempted by the Imperium.
