An emergency transmission has been recieved by the Imperial fleet from the planet Volistad, a major supply world for the crusade. The harm that could be done if the ork threat is not stopped could cause the crusade to grind to a halt.
Warmaster Xerxes has dispatched Lord Commissar Holt with a contingent of Imperial troops to secure the supply lines into the Midas sector.
