Orks charge Praxis City. Carcharadons rescued by imperial cult

In a bizarre sequence of events the Carcharadons found themselves in the debt of the Imperial Cult on Hexis just days after they had purged the militia forces from the centre of Praxis. Following that engagement a small force of astartes had been stationed in the tight confines of the city centre ruins, ever vigilant for attack by the forces of chaos surrounding them on three sides. 

What they did not expect was an assault by the orks of Von Bismorck, who had arrived on Hexis after rumours of a “big fight” had reached the greenskin leader. After defeat at Hylas many thought this particular warband had been scattered, but the familiar greenskins turned up at Hexis and immediately threw themselves at the biggest prize right in the centre of Praxis. Whether the forces of chaos actually exerted any control over the orks is unknown, but soon despite being relatively few in number, the greenskins had overrun the centre of the ruined city and trapped the Carcharadon squad underground in the tunnels around the device chamber. 

Unable to immediately counter this emerging threat general Konev was at a loss to support the space marines, but the Imperial Cult, determined that the prize should not fall into xenos hands, launched their own initiative into the central ruins. A fierce battle erupted in the centre of Praxis as two irregular forces battled for control of the strategic heart of the campaign, as the chaos and imperial leaders looked on in surprise. The righteous fury of the imperial militia overwhelmed the orks, retaking the centre of the city and rescuing a somewhat bemused squad of carcharadons from the underground crypts. Whether this act would be enough for the imperial cult to be accepted by the hard line astartes was unknown, but the marines had the irregulars to thank for their salvation.
