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.
