The Blood Angels, reunited with Captain Orpheo, ascend to the heart of the cult's corruption - and in doing so, call down the wrath of the Magus. Meanwhile, the Primus leads hordes of cultists to surround the Sons of Sanguinius. Aboard the Sword of Baal, Livia will do anything necessary to ensure the cult cannot take the ship - even if that means destroying it. Yet even now, perhaps the Techmarine Hadrael offers slim hope of redemption.
The Blood Angels strike cruiser Sword of Baal hangs in orbit over the planet Niades, trapped by warp storms. Aboard, the ship's complement of Space Marines chafe at their inaction.
On the trail of their missing Captain, the Blood Angels deploy to the surface of Niades by Drop Pod. Their journey is not a smooth one, and they must regroup to explore the ruined city at the base of the docking tower.
As the Blood Angels on the surface of Niades cut a course through the entrenched Genestealer Cultists towards the signal from Captain Orpheo's beacon, the situation aboard the Sword of Baal goes from bad to worse.
