Later, Loken finds Karkasy and swears him to silence. When Karkasy questions Abaddon about a silver coin he handed to Erebus at the start of the meeting Abaddon tries to kill him, but Loken holds him off long enough for Karkasy to escape. First Captain Ezekyle Abaddon interrupts the pair, angrily rebuking Karkasy for impugning Erebus's reputation and scorning Loken for keeping company with remembrancers.

Remembrancer Ignace Karkasy reports back on the meeting to his sponsor, Captain Garviel Loken, revealing that Erebus manipulated Horus into becoming enraged at Temba and must have an ulterior motive for wanting Horus to go to the moon.

Enraged, Horus orders an immediate attack on the moon. A War Council is convened on Davin's surface where Erebus reveals his reason for summoning the Warmaster to the planet: its planetary governor, Eugen Temba, has turned against the Imperium and betrayed Horus after taking his forces to the planet's moon to put down a rebellion by the Davinite tribes there.

They are joined by Petronella Vivar, scion of a Terran noble house who becomes Horus's documentarist.
