  • Cisrain led Gamma World forces through the Webway, where they used the Neutron Sweep to destroy the awakened Nicaros Dynasty and began clearing neighboring worlds for Gamma World’s excavations.
  • Lion El'Jonson met Gamma World’s forces, accepted cooperation after seeing their technology, and discovered that Chaos corruption had spread among the Fallen Angels and aboard his warship.
  • Cisrain returned to Gamma World with Little Gray and Adam, while researchers studied Blackstone Fortresses and C'tan fragments and prepared a containment device to repair the Warp breach at Is III.
  • Gamma World’s device restored the barrier between the Warp and the material universe at Is III, while the Emperor stirred and Malcador learned that the Eye of Terror could also be repaired.
  • As Imperial reinforcements approached Cadia, Vashtorr corrupted their fleet and took control of a warship, causing its crew to launch a cyclonic torpedo at the planet.
  • The Cadians mistook the Chaos withdrawal for victory before the torpedo struck Cadia and its fires consumed the battlefield and those sheltering in the fortresses.

Ch. 231Malcador, Fly Without Fear; The Emperor Will Take the Fall

Cisrain used Malcador’s renewed psychic strength to draw attention away from Gamma World while secretly preparing the world to resist the Imperium, Necrons, and other powers. Gamma World gained Blackstone Fortress data and a Webway route map, but still needed Necron phase-engine technology to complete its defenses.

  • Malcador’s psychic power fed back into Cisrain, who redirected it into the Blackstone Fortress rather than accept a Warp-bound power.
  • Cisrain anticipated that Malcador’s return would attract the Imperium and potentially provoke the Aeldari or Necrons, so he continued preparing Gamma World’s escape and defenses.

Ch. 236New Energy Technology, Healing a Warp Rift for the First Time

Malcador and the Black Templars prepared to secure Cadia while Gamma World's researchers uncovered how the Blackstone Fortress could manipulate reality and potentially repair Warp rifts. With approval from the Chief and World Lord Cisrain, they planned to test the technology on Is III and accelerate their research using temporal fields.

  • Malcador urged the Black Templars to use Cadia's Blackstone constructs quickly, warning that Abaddon could return and that Malcador needed to return to the Imperium.
  • Gamma World's researchers expanded their computing capacity and analyzed Blackstone Fortress data while developing a direct stellar energy extraction device.
  • Researchers discovered that the Blackstone Fortress had been forged by Aeldari gods to fight the C'tan by using Warp power to alter the material universe.
  • The scientists concluded that the imprisonment of the C'tan had left Chaos's Warp rifts unrepaired and considered using C'tan fragments to mend the breach on Is III.
  • The Chief and World Lord Cisrain approved the research, and the team planned to slow time tenfold while the Blackstone Fortress traveled to Gamma World over three days.
  • An Ozrax researcher warned that rival laboratories might also obtain the data, prompting laboratories across Gamma World to hoard technology and report discoveries upward.

Ch. 237Necrons: Who's Disturbing My Sleep?

Gamma World's fleet located a sleeping Necron Dynasty and prepared to seize its technology, while Oukekaosi led them toward his rival Nicaros. Nicaros awoke to find Gamma World's forces approaching, and a Necron noble's attack on a detector revealed the colossal weapon waiting in orbit.

Ch. 238Gamma Empire: You're the One We're After

Oukekaosi revealed that he had infiltrated the Nicaros Dynasty and planted a virus to sabotage its defenses while Gamma World attacked. Gamma World’s Neutron Sweep erased the planet’s life, and the assault continued as the program began its ten-minute firing cycle.

  • Oukekaosi told Nicaros that he had planted a virus to awaken Necron soldiers and exploit the dynasty’s resources, blaming Nicaros’s allies for abandoning him.
  • Oukekaosi reflected that Gamma World’s technology might exceed the Necrontyr’s limits and hoped to take advantage of the conflict to rebuild his own dynasty.
  • A noble fired a bullet that struck and destroyed a droplet-shaped detector as the Neutron Sweep appeared above the planet.
  • Gamma World activated the Neutron Sweep and fired a neutron plume that shattered living beings at the atomic level and tore apart Necrons emerging from stasis.
  • The first sweep exterminated all surface life, and the Neutron Sweep continued for ten minutes, widening openings and destroying everything its streams reached.

Ch. 239Cleaning Operation!

Oukekaosi handed Gamma World the Necron technology he had seized, and Gamma's forces began securing Energy Planet 2 while preparing to wipe out nearby threats. As the cleaning operation began, Lion El'Jonson arrived at a vast fortress world.

  • Oukekaosi gave Gamma World the captured Necron data and directed its forces toward neighboring enemies.

Lion El'Jonson followed the Gamma Fleet to a world its neutron weapon had cleansed of all life and sought a way to reach Gamma World. He introduced himself to the fleet, whose crew identified him as a Primarch and noted that Gamma World could manufacture Primarchs, though the ones made from traitors’ souls would be incomplete.

  • Lion El'Jonson led the Fallen Angels through the Warp, defeated the Anti-Gamma World Alliance, and forced a pirate lord to guide them to his lair.

  • Skaiqi agreed to meet Lion El'Jonson aboard a Voyager and planned to report the proposed cooperation to Gamma World's Chief Council.
  • Lion El'Jonson boarded the Voyager with Fallen Angels, expecting a show of force, and found more than a hundred Gamma World Space Marines and over a dozen Dreadnoughts awaiting them.
  • Gamma World's technical sergeant scanned Lion's party for Chaos contamination, and Lion allowed the inspection to proceed.
  • The technical sergeant detected Tzeentch's influence on a Fallen Angel and activated a purging program, revealing Chaos scripture on the warrior's armor.

Ch. 242Playing Lion El'Jonson with a Song and a Dance, Putting Fallen Angels to Work

The Techmarine revealed that Gamma World could treat Chaos-related mutations and might even resurrect the dead, leaving Lion El'Jonson curious about its capabilities and the Fallen Angels unsettled by their past killings. Sidler brought them aboard Gamma World's vast, well-equipped warship, where its technology and resurrection practices challenged their understanding of the Imperium.

  • The Techmarine explained that a Fallen Angel's mutation was physical and treatable, then warned that the others carried abnormal data and might mutate unless they obtained restorative treatment.

  • When asked whether they could do the same, the Fallen Angels reluctantly answered, "More or less."

Ch. 243You Provide the Weapons, We Do the Work

Ch. 246Gray Wind's Unusual Personality, on the Eve of the Great Rift

Cisrain weighed Cadia’s Blackstone Pylons and the unavoidable threat of the Great Rift, then led his group toward Gamma World to prepare for the coming conflict. Along the way, Little Gray devoured a factory and mine before reluctantly following the fleet home.

  • Cisrain judged that Cadia’s Blackstone Pylons could delay the Great Rift but risked tearing the galaxy apart, and he decided to return to Gamma World.

He arranged for Little Gray to consume four million tons of ore and questioned Adam about humanity’s fallen Golden Age.

  • Cisrain followed the Gamma Fleet back to Gamma World after Little Gray left the planet’s mine stripped bare.

Research into the Golden Throne and the Emperor suggested a possible way to make him stand, but Cisrain recognized the catastrophic risks and decided Warp breaches near Gamma World had to be sealed first.

  • Cisrain learned from Adam’s Golden Age knowledge that Chaos, especially Tzeentch, had manipulated rising civilizations and pushed humanity toward ruin.

Ch. 249Stitching the Warp

Ozrax researchers developed a containment membrane to isolate the Warp from the real universe and received approval to test it with a piece of a C'tan fragment. They chose the weakened fragment on Energy Planet 1, while the Deceiver remained trapped and Vetius continued gathering technology from engineers it beguiled.

  • Brian explained that the containment membrane could seal off a star sector, though it would slow light and movement within it.
  • Ozrax researchers said a C'tan fragment might help expand the membrane, and the Chief Council authorized the experiment.
