Chapter Summaries

Gamma World's fleet attacked Biel-Tan Craftworld with a distant bombardment that overwhelmed the Aeldari's confidence in their defenses. The chapter ended as the Craftworld's void shield began to fail and its people fled beneath the incoming fire.

• Biel-Tan's Seer Council reassured the Aeldari that their layered defenses could repel the enemy, while Farseer Arthas failed to foresee the danger.
• Gamma World's fleet opened fire, and its first enormous lance struck Biel-Tan's void shield with enough force to shake the entire defense.

• Karandur rose from his throne as Aeldari on the ground saw the shield breaking and shouted for their people to evacuate.

Gamma World devastated Biel-Tan Craftworld with relentless bombardment while its defenders struggled to retaliate. The Aeldari patrol fleets were teleported into Slaanesh’s Palace of Pleasure, and Biel-Tan’s Seer Council sensed that the souls of their ancient heroic spirits were being torn apart.

• Gamma World shattered Biel-Tan’s satellite worlds, destroyed its void shields, and bombarded its surface, cities, and orbital installations.
• Karandur demanded that the seers identify the enemy as Biel-Tan’s weakened defenses left it unable to strike Gamma World’s distant fleet.

• Gamma World teleported the Aeldari patrol units into Slaanesh’s Palace of Pleasure, where they were trapped amid endless feasting and felt their souls being drained.
• The Biel-Tan Seer Council sensed that their ancestors’ heroic spirits were being torn apart in the Warp and feared Slaanesh had captured them.

The ancestral spirits of Biel-Tan exposed themselves to protect their people, while Wolfe’s patrols boarded Gamma World’s ships and discovered that the human forces could counter their speed. Gamma World crushed the Aeldari attack and prepared to destroy Biel-Tan, leaving the Craftworld’s people with no apparent escape as Slaanesh turned toward their souls.

• The ancestral spirits of Biel-Tan awakened runes and wraith shadows to shield the Aeldari, drawing the Dark Prince’s attention and urging their people to flee.
• Wolfe blamed the Gamma Fleet for destroying Biel-Tan’s spirit-stone defenses and led his patrols in an assault on the human warships.

Gamma World's defenders pushed the invading Chaos and xenos forces into retreat, while Craftworld Altis advanced toward the Blackstone Fortress and Yvraine learned that Biel-Tan Craftworld had been destroyed. The Visarch urged Yvraine to flee to another galaxy as Gamma World's retaliation loomed.

• Gamma World's workers, soldiers, and civilians resisted the invaders across Karamat and other regions, recapturing territory and sealing breaches into realspace.
• A foreman from the Central Dome Factory led a counterattack that captured a human traitor leader and intercepted intelligence, while villagers and an eleven-year-old child helped defeat Chaos forces elsewhere.

• The Visarch asked Yvraine to leave with him for another galaxy.

Yvraine abandoned the attempt to save the Eldar on Gamma World and summoned Ynnead to gather the souls of the dead before Slaanesh could claim them. As the Eldar retreated and discovered the supposed weapon was too vast to take, Craftworld Altis learned Biel-Tan had been destroyed and found Gamma World’s fleet surrounding its ships.

• Yvraine refused Savich's invitation, chose to leave, and committed to gathering the Crone Swords rather than saving the Eldar on Gamma World.
• Yvraine summoned Ynnead, whose skulls absorbed the unclaimed Eldar souls on the battlefield.

• Tzeentch searched for a new plan to restore the Second Imperium’s former state and saw The Emperor rise.

Szarekh returned from the Webway and investigated Gamma World's role in the Necrons' stalled search for souls. His projections revealed that Gamma World could eliminate unpredictable variables, though he could not identify the person or object responsible.

• Necron Overlords challenged the delay in restoring their souls and demanded a clear timeline, while the informed rulers could offer no proof or schedule.
• Szarekh appeared before the arguing Overlords and reminded them of his ongoing efforts to find a way to restore the Necrontyr's souls.

As the Imperium and other factions faced escalating wars, a band of Great Crusade-era Space Marines emerged from the Warp near the Great Rift and found themselves in a devastated region of the Milky Way. After battling Chaos forces, they uncovered an unfinished metal body being assembled as a demigod, while similar altars appeared on nearby worlds.

• The Imperium continued using delaying tactics as the Necrons seized bordering territories, while Chaos forces rallied around Huron Blackheart and the Aeldari resurfaced under Eldrad's fearful prophecies.

• The travelers discovered that the Webway’s depths connected to the place where The Emperor stole the Four Gods’ spark and Horus fought tens of billions of daemons, so they prepared to proceed carefully.

Gamma World's fleet traveled through the ancient Webway toward Molech, where the Emperor had entered the Warp and gained forbidden power. As Warp energy surged in a damaged region, the fleet sensed an enormous creature sleeping in the clouds above.

• Gamma World's fleet monitored the low Warp-energy levels and discussed the Old Ones' Webway while an Adeptus Custodes warned the Space Marines not to draw Chaos's attention.

• Chaos daemons poured into the city from the sky, streets, and buildings, and the forces prepared to defend themselves against a horde potentially numbering in the billions.
• Cisrain and the others activated Great Devourer Mode, strengthening their living armor while consuming nearby matter and remaining wary of the energy they gained from killing daemons.
