Mike, Nero, their sister, and their veteran father prepared for evacuation as a Warp Storm brought demons to Dianka, but the convoy was attacked by a force bearing Chaos symbols. The family escaped aboard a Mammoth while the Spartan reservists and Kriegsmen stayed behind to fight, facing enemies armed with Bolter Rounds and strange energy beams.

• Mike brought Nero home as the sky over Dianka filled with strange lights, and their father armed himself while their sister hurried outside.

• Rebel ground forces began exchanging heavy fire with the defenders, using green and dark red beams and standard Bolter Rounds.

After the traitor commander recognized a golden power protecting the squad leader, the young fighter slaughtered the remaining enemies and collapsed unconscious.

• Krieg soldiers and six reservists battled the rebels, and the reservist squad leader and his brother charged into the wheat field, where they discovered their enemies were human traitors in Chaos armor.

A mysterious woman appeared on Dianka and effortlessly killed the Traitor Terminators, then told Dad she was a former Queen of Olympus seeking to see her son again. In orbit, the Sons of Horus overwhelmed Dianka’s defenders, but thirty-one Spartans teleported aboard the enemy flagship after their own ship was destroyed.

After Dianka’s forces defeated the invading faction, Sui Bian considered what the enemy’s universe might be and called his sons together. He admitted he had concealed his visions of the Horus Heresy, then began explaining them to the Primarchs as the chapter ended.

• News reports announced that the Primarch Governor of the Frontier Fortress had defeated the invading human faction at Dianka, and residents in New Raccoon City reacted by planning aid and military support.
• Sui Bian reviewed footage of Abaddon’s defeat and concluded that the universe beyond the Vortex Space Gate might differ from the Warhammer history he knew, possibly because Horus had succeeded in his rebellion.

• Robert asked whether Sui Bian already knew about that universe, and Sui Bian apologized for keeping his visions from his sons.
• Sui Bian described the causes and consequences of the Horus Heresy to the Primarchs as prophecies and visions he had experienced.

Sui Bian prepared to lead a crusade through the Vortex Space Gate against the New Imperium of Man, assigning Magnus to protect humanity’s territories and his sons to assemble the expedition. After the system revealed that Horus Lupercal had received Chaos’s blessings and made killing him a mission, Sui Bian headed for Dianka while John went to meet Hera.

The chapter recounted how Horus and the traitors conquered the Imperium, killed several loyalist Primarchs, and established a New Imperium that exploited the Emperor.

• On Nucia, Angron’s World Eaters and the Imperialis Militia awaited the Death Guard while the World Eaters slaughtered the planet’s inhabitants for fear tithes.

World Eaters slaughtered the people of Nucia while a hidden Underground City prepared to evacuate its inhabitants. Lady Xisia and Valentina’s Sisters of Battle underestimated the traitors until the World Eaters broke through and exposed their overwhelming strength.

• The Clearers and UNSC fleet prepared to seize the Nucia system’s orbits, while the World Eaters’ Primarch arrived on Gladiator with bodyguards and Terminator veterans.

Angron and his World Eaters were trapped on the Gladiator and lured into an arena, where he fought a more human version of himself. Human Angron defeated him and declared that he and the captured World Eaters would be studied as experimental subjects.

• Angron led more than a thousand World Eaters through the Gladiator's jungle, killing four of his own guards in a fit of rage before accepting a scout's report of a nearby arena.

• A Son of Horus reported that contact with the World Eaters and Angron had been lost, so Horus ordered Mortarion to halt and rendezvous with the Word Bearers in the Pious Sector.
