Second Cordanian-Severan Dominate War

History
The Cordonian regiments had fought fought over a hundred wars on the Spinward Front against the Severan Dominate, that has seceded from the Imperium of Man under the leadership of the former Sub-sector Governor of the Periphery, Duke Severus XIII of Kulth. The 501st reclaimed over a dozen planets until the 13th Black Crusade had begun. The majority of the Regiment was sent to aid the Imperial forces fighting the Forces of Chaos. So all they could spare was several platoons aiding many other regiments such as the Death Korps of Krieg, Tallarn Desert Raiders, the Armageddon Steel Legions, and the Cadians themselves. They also have to battle the Orks of WAAAGH! Grimtoof.
