After months spent in the service of the Chaos god Slaanesh, the ruling classes of the Contqual sub-sector have finally brought true damnation upon their people – innumerable hordes of foul and lascivious daemons swarm from a tear in the fabric of reality to embrace their mortal pawns and drive them on to ever more depraved acts of worship. It falls to the merciless Space Marines of the Iron Hands Chapter to cleanse these worlds of the warp’s unholy taint, and it is upon the surface of Shardenus that the fate of a billion lost souls will be decided.
