Chapter Summaries

Boss Slick surveyed the Ork Warbosses who had expanded across the Octarius Sector and ordered Iron Claw to attack the Tyranids. With the Tyranids controlling most of the sector and Boss Slick committed to attacking Octaria on schedule, he planned a decisive battle designed to impress all the Orks watching.

• Iron Claw reported that he had conquered more than ten systems and gathered Boyz from several Ork clans, and Boss Slick ordered him to stop hoarding troops and attack the Tyranids.
• Boss Slick contacted dozens of other Warbosses who had branched off from the Screw Clan and spent three days learning about their forces and battle situations.
• Boss Slick assessed the sector, finding that the Tyranids controlled most developed systems while the Screw Clan and its splinter Bosses held scattered positions, especially in the south.
• Boss Slick concluded that driving the Tyranids from the sector would require time, but he could not delay his promised attack on Octaria.
• Boss Slick counted 150,000 warships available for a decisive battle and sought a victory that would make a grand impression on the Orks of Octarius.

• Boss Slick sent Dio the campaign’s time and location before ending the communication.

After Kuka’s Psyker Boys completed a taxing long-distance communication, Boss Slick used his growing mechanical authority to deconstruct Necron wreckage and organize the Mekboys rebuilding his ship. He aimed to master the Necrons’ anti-C’tan technology before repairs finished in fifteen days, potentially giving his ship a third devastating main gun.

• Kuka ended the Psychic Communication after leading several thousand Psyker Boys through the exhausting effort, and Boss Slick praised him.
• Boss Slick had Bad Gambler collect Necron wreckage, then used his mechanical authority to deconstruct a Gargant loaded with Ribz junk and study its machinery.

• Boss Slick planned to focus on Necron anti-C'tan weapons during the fifteen days scheduled to repair his ship, with the goal of building a C'tan Shard Cannon.

Boss Slick sent Kuka and the Psyker Boys out to spread the Screw Clan’s victories and recruit Orks for a galaxy-wide Waaagh. He then rallied his assembled fleet and laid out a route through the Great Rift and several Imperial segmentums.

Boss Slick sent his Ork fleets toward Octaria while the Great Devourer weighed how to respond to the coming assault. Tzeentch then contacted the Great Devourer, revealed he could penetrate its defenses, and began overpowering its attempts to resist him.

• Boss Slick ordered his fleet to set out for Octaria, with more Ork fleets expected to join the attack.
• The Great Devourer considered defending Octaria or striking the Screw Clan's exposed forces, but its calculations favored neither outcome.
• Tzeentch spoke to the Great Devourer and urged it to choose the plan to defend Octaria.
• The Great Devourer refused to answer and used more Calculation Units to contest Tzeentch through magic.
• Tzeentch explained that he could still penetrate the Great Devourer's defenses, and his projection grew to match it.

Tzeentch tried to enlist the Great Devourer against the Emperor’s plan and warned that Boss Slick could unite the Orks of the Octarius Sector. The Great Devourer refused Tzeentch’s aid and prepared the Tyranid swarm for an all-out war in Octaria.

• The Great Devourer stopped its losing contest with Tzeentch and asked what Tzeentch wanted.
• Tzeentch explained that it opposed the Emperor’s plan and warned that Boss Slick could unite the Orks under an Ork emperor.
• Tzeentch offered Thousand Sons and Daemon reinforcements if the Great Devourer sent its projection into the Warp, but the Great Devourer refused the offer.

Tzeentch told Magnus that the Emperor’s divine throne had been forged and that the Emperor might ascend soon, while secretly wondering whether Magnus would become the God of Vengeance or the Dark King. After the Warp Storm failed to stop the Orks, Magnus planned to help Fulgrim muster an army, but Boss Slick’s fleet reached Octaria first and launched a devastating surprise attack on the Tyranids.

• Tzeentch questioned Magnus about the Thousand Sons’ magical warships and said they needed more forces to fight the Emperor’s Ork Clone.
• Tzeentch warned Magnus to respect the Emperor, whose divine throne had been forged, then privately said Magnus had to choose between becoming the God of Vengeance and the Dark King.
• A Thousand Sons sorcerer told Magnus that the Warp Storm had failed to stop the Orks, who were traveling to Octaria through normal space using the Inertialess Drive.

• After two months of travel, Boss Slick and the fifty-thousand-strong Screw Clan arrived at Octaria and surprised the Tyranid fleet.
• Boss Slick fired the C’tan Shard Cannon, destroying nearly a hundred thousand Tyranid bio-ships, then ordered the Screw Clan to crush the Tyranids.

Boss Slick’s Ork Fleet opened its attack on the Tyranids in the Octaria System, inflicting heavy losses but discovering that the Tyranids’ corrosive countermeasures made a direct exchange costly. He then used a Dimensional Rumble Cannon barrage to herd the Tyranid ships into a dense formation and fired the C'tan Shard Cannon at them.

• Boss Slick ordered the Ork Battleships to fire their Dimensional Rumble Cannons, destroying many Tyranid ships and splitting the battlefield with spatial rifts.

• Boss Slick directed his fleet toward Ork V as Tyranid warships pursued and surrounded them.

The Great Devourer organized the Tyranid fleet to protect the Norn Queen cocoon and destroy Boss Slick, while stellar eruptions killed Tyranid ships en route to Octaria. As Boss Slick’s battle stalled, Rottooth tried to bring delayed Ork reinforcements through the Warp despite a storm raised by the Thousand Sons.

• The Great Devourer arranged a defensive line, a pincer attack, accelerated incubation of the Norn Queen, and the arrival of Tyranid reinforcements.
• Solar prominences erupted from Octaria’s star and burned over a thousand Tyranid Bio-ships as the fleet passed.
• Boss Slick questioned Rottooth about the missing Ork fleets, and Rottooth promised to bring them over.
• Rottooth led roughly five thousand ships away from Boss Slick’s fleet and learned that a Warp storm was blocking the Weirdboys.
• Rottooth ordered the Ork ships to activate their Warp Engines and open gates into the Warp, while the Great Devourer held back its Warp projection.

Rottooth’s insults unexpectedly guided Ork warships lost in the Warp Storm back to Octaria, turning the battle in Boss Slick’s favor. The Great Devourer withdrew toward Ork V, where it planned to regroup with reinforcements and a half-hatched World Devourer.

• The World Devourer broke free of the Great Devourer's mental suppression and attacked the Ork Fleet, prompting the Great Devourer to coordinate a pincer assault.
• Tyranid warrior bugs damaged Boss Slick's Ship and its Dimensional Rumble Cannon, while the Ork Fleet heavily wounded the World Devourer but could not kill it.

• Dio arrived with a fleet and fired the Dio Cannon twice, scorching both halves of the World Devourer.
• Dio aimed a third shot at Ork V, and Boss Slick urgently warned him that the planet was needed for mining, but Dio had already pushed the firing lever.

• The Great Devourer called for reinforcements from across the Octarius Sector as it prepared for a war of attrition against Boss Slick.
• Kundra considered launching a Great Waaagh to demonstrate his strength when an orderly reported that a Weirdboy from the Screw Clan had come to speak with him.
• Kundra ordered the orderly to bring in Kuka, then sent him to run laps for violating uniform regulations.
• Kundra reflected on his belief that he might be Gork and Mork’s Chosen and wondered what Kuka would say about Boss Slick.

Kuka challenged Kundra to a contest of strength to earn permission to spread Boss Slick's Great Waaagh, and defeated him by drawing on his determination. Kundra then allowed Kuka to connect his tribe to the Waaagh! field, where a battlefield broadcast of Boss Slick fighting Tyranids began to excite the Blood Axes.

• Kuka proposed a wrestling contest with Kundra, wagering permission to spread Boss Slick's Great Waaagh.
• Kundra and Kuka grappled, but Kuka's resolve let him push Kundra out of the circle despite Kundra's greater size and mechanical leg.

• Kuka’s broadcast spread through the Blood Axes as Mekboys and Painboys built devices that let more Orks watch the battle footage.
• Orks fought over a small monitor, so Mekboys and Big Meks created Holographic Projections that showed the Octaria Campaign across the planet and beyond.
• The footage filled Kundra’s Waaagh! Field with battle lust, and Kundra began boarding ships to take his forces to the Octaria system.
• Kuka planned to leave Kundra’s tribe sooner, while the Psyker Boys continued promoting the Octaria Campaign and Boss Slick to Orks across the Galaxy.
• On Number 3, Grom led Snakebites and Screw Clan Boys in another attack on Capello while Duncehead worked on a Zzap Gun for their Mechanical Squiggoth.

Grem and Goldtooth’s evenly matched Ork armies fought until footage of Boss Slick’s war on Octaria showed them how small their conflict was. They reconciled in the Euronia System and prepared to join Boss Slick’s Great Waaagh, while Rambo set out on a separate campaign.

Kidd and Luo Wen devised a risky way to propel the Ork Battle Star using the expansion of the universe, hoping to join Boss Slick's Great Waaagh. Kidd approved the plan and ordered them to give the Battle Star a heart and set it moving.

• Kidd inspected the Ork Battle Star's unfinished faster-than-light engine section while waiting for Boss Slick to return with a solution.
• Luo Wen presented his theory that the universe's expansion only appeared to be slowing because newly forming universes squeezed it.
• Luo Wen proposed harnessing ripples in the universe's expansion to carry the massive Ork Battle Star faster than light.
• Kidd warned that the uncontrolled journey could send them into another universe with dangerous physical laws, but Luo Wen dismissed the risk.
• Eager to join Boss Slick's Great Waaagh, Kidd accepted Luo Wen's plan and ordered him to get the Ork Battle Star moving.
