The '''{{PAGENAME}}''' was a devious [[Alpha Legion]] [[Champion]] who was among the [[Chaos]] forces that invaded the [[Imperium]] [[Hive World]] [[Tholdax]]. {{Fn|1}} An Imperial strike force later arrived to defeat the invaders, and the Serpent's Shadow took charge of the Chaos forces within [[HiveGanymede]] '''Ganymede'''. Once the strike force reached Ganymede, however, the Alpha Legion Champion used his incredible tactical acumen to stall the Imperials' advance, despite his forces being outnumbered three to one. When they learned of his existence, the Imperial strike force marked the Champion for death, and a [[Kill Team]] led by the [[Ultramarines]] [[Space Marine Sergeant|Sergeant]] [[Agrippius]] later successfully tracked down and destroyed the unmarked [[Rhino]] the Serpent's Shadow used to travel within Hive Ganymede.{{Fn|1}}
