Chapter HistoryEdit

Notable CampaignsEdit

  • The Bifrost Uprising (Unknown date M41) - When Chaos-led insurgents succeeded in corrupting several regiments of Bifrost Huscarls, the Viper Legion deployed in limited numbers to Bifrost. To maximize their effectiveness, the Viper Legion placed some of its members at the head of smaller detachments of PDF or Imperial Guard regiments. The Viper Legion would ultimately be reinforced by the Minotaurs Chapter, whose intervention would ultimately lead to the Bifrost Incident. Having been awarded brevet command of a detachment of loyalist Huscarls during the extermination of the Traitor 2-19th Regiment, Sergeant Augustine encountered a blood-covered and damaged Dreadnought he mistook for an engine dedicated to the ruinous powers. Opening fire on what he believed was the enemy, his target proved in fact to be Hecaton Aiakos, a Dreadnought of the Minotaurs Chapter. Thus provoked, Aiakos charged and massacred 37 Huscarls, a Leman Russ and Augustine himself before being ordered to stop.
