Leinhert was the Emperor's Champion of the Black Templars' Vornn Crusade.[1]
History
The ill-fated Crusade had sought to track down and slay the Daemon Primarch Magnus in M42. However it ended in failure, with Leinhert falling in battle and his Black Sword becoming lost to the Black Templars. Sometime later, though, Marshal Maxim received visions from the Emperor, which bade him to recover Leinhert's lost blade. Maxim obeyed and has launched the Tanhelm Crusade into the Kerabdim Nebula, where the visions place the relic.[1]
