He informally fought beside the [[Indomitus Crusade]]'s [[Fleet Secundus]] [[Battlegroup Betaris]] on two occasions, before slipping back into the void each time. But the predatory menace he exuded, led the Battlegroup's forces to give the Carchardons a wide berth. Those that saw MannorMannfor's warriors in battle, gave him many grim epithets and the sites of bloody slaughter he left in the [[Mhoran Belt]] led his name to become an invocation of terrible vengeance by many within Fleet Secundus. Once such instance, was when the [[Word Bearers]] claimed the '''Castellus Sanctic''' citadel on [[Budor V]] and repelled numerous sieges led by Fleet Secundus to dislodge them. When the Traitors' [[Diabolist]]s began to summon [[Daemons]], Mannfor led his warriors in a sudden strike that left the citadel filled with the Word Bearers and Daemons' bloody remains.{{Fn|1}}
