Chapter Summaries

Lin Fan explained to Kaiser Whitefang and Wodhaus why he was promoting Commissar Cain: the Imperium could not afford the centuries required to conquer the T'au Empire, whose future expansion would make it increasingly dangerous. The discussion ended as Lin Fan began describing the T'au Empire’s predicted transformation.

• Colvin left after Kaiser Whitefang teased Lin Fan about his popularity with women, and Kaiser invited Lin Fan to join a secret meal.
• Lin Fan followed Kaiser to the kitchen, where Wodhaus and Bennett were eating roasted meat with the cook, Flavor Supreme.
• Wodhaus used psychic power to send Flavor Supreme away so the group could talk privately, leaving him as an alarm.
• Lin Fan said his own achievements were kept quiet by the Imperium, while Commissar Cain was already famous among the T'au.
• Lin Fan explained that conquering the T'au Empire would take at least two centuries, which the Imperium could not spare amid threats from Orks, Necrons, and other remnants.
• Lin Fan said prophecy foretold a Fourth Expansion that would turn the T'au Empire into a nervous regime focused on purges and extermination.

The chapter surveys the T'au Empire’s place among the galaxy’s powers, contrasting its efforts to spread the Greater Good with the harsher realities of the Warhammer universe. It recounts how later expansions humbled the T'au and leaves them portrayed as a tightly managed society that still looked comparatively bright beside the Imperium.

• The chapter described the T'au as an emerging power whose expansion and claims of superiority drew hostility from older galactic factions.
• It recounted how the Third Expansion provoked stronger Imperial counterattacks and threats from the Necrons and Orks.
• The Fourth Expansion’s experimental Warp engines exposed the T'au to the Warp and a human-looking god of the Greater Good, driving survivors toward purges.
• The Ethereal Council established the Re-education Department and targeted unstable elements, while humans who resisted or joined the Greater Good were killed.
• Tyranid and Chaos threats pressured the T'au during the Fifth and Sixth Expansions, pushing the empire toward a more cautious policy.
• The chapter noted that the T'au provided extensive services but arranged nearly every aspect of their citizens’ lives.

Lin Fan explained his plan to win at Mugula Gulf, manipulate the T'au Empire into accepting a treaty, and use the threat of a Tyranid invasion to pressure it. He left the details of his scheme undisclosed while considering how to remove Supreme Ethereal Aun'Va.

• Lin Fan told Kaiser Whitefang, Wodhaus, and Bennett that the Imperium would win at Mugula Gulf, stage Cain's capture, and force the T'au toward a treaty.
• Lin Fan described how The Emperor would guide the T'au and the Imperium toward knowledge of the Tyranid hive fleet, drawing Imperial forces east and making Shadowsun seek peace.
• Bennett compared Lin Fan's elaborate plan to the schemes of Tzeentch's followers, and Lin Fan defended his newfound strategic thinking.
• Kaiser Whitefang asked whether casualties would make the T'au hate the Imperium, and Lin Fan said they cared more about attacks on the Greater Good than personal losses.
• Lin Fan decided that Aun'Va had to die, but not at the Imperium's hands.

After Wodhaus foresaw a Tyranid invasion threatening the T'au Empire, Imperial divinations confirmed the danger and forced the expedition to postpone its full assault. The commanders changed their objective to severing the T'au Empire's reach in the Damocles Gulf while preparing for the Tyranids.

• Wodhaus entered a three-day trance and saw Tyranids attacking the T'au Empire, then gathered the Space Wolves and announced his prophecy.
• Psykers across the fleet repeatedly used the Emperor Tarot, and the assembled leaders received grim omens of calamity.
• The Librarians completed thirteen days of joint prophecy and confirmed that the fleet should delay its offensive and prepare defenses against the Tyranids.
• Captain Raedel argued that the Imperium should avoid crippling the T'au Empire before the Tyranids arrived.
• Sage Kaos reported that the T'au Empire's territory held no important strategic resources, so the commanders chose to conquer the Mugula Gulf and sever the empire's reach in the Damocles Gulf.
• The sector fleets and Space Marine Chapters departed as the expedition's commanders prepared for the revised campaign.

The Imperium’s forces prepared to seize Mugula Gulf, while Raven Guard infiltrators sabotaged the T’au planet’s defenses and Sage Kaos activated the Mechanical Ark’s weather controller. The radiation storms began to dissipate, clearing the way for an assault.

• The expeditionary fleet split up to reinforce its sectors and prepare for the approaching Tyranid swarm, while a force remained to conquer Mugula Gulf.
• Corvin Sevraks and the Raven Guard infiltrated the T’au gun emplacements and caused their turrets to explode before they could fire.
• Sage Kaos activated the weather controller aboard the Mechanical Ark, the Ten Thousand Miles of Sunshine.
• A blue beam disrupted Mugula Gulf’s radiation storm, rapidly dissipating it.

Lin Fan and the 37th Regiment landed in the desert after the fleet exposed and bombarded the T'au ambush forces. The Imperium assembled its armored assault force, including Doomblade tanks, as the troops prepared to encircle the T'au city.

• The fleet bombarded the T'au ambush units after Sage Kaos cleared the radiation storm, burying Hammerhead teams beneath superheated sand.
• Lin Fan and the 37th Regiment disembarked, and Lin Fan ordered every squad to report suspicious activity to Rebecca.
• Imperial transports deployed Leman Russ tanks, while Doomblade tanks dropped directly from the fleet onto the landing field.
• Colonel Dektar introduced the Cadia Advance Hell Tank Regiment to Commissar Cain and Lin Fan and pledged to coordinate with their attack.
• Rebecca complained to Lin Fan about the Doomblades' slow speed, and Lin Fan reflected on the Imperium's reliance on overwhelming frontal warfare and the Space Marines' surprise attacks.

Shadowsun met Supreme Ethereal Aun'Va and Director Eternal Explorer, who unveiled a plan to block Imperial forces from crossing Damocles Gulf with Warp transmitters. Shadowsun doubted the technology's reliability, but Eternal Explorer dismissed her concerns as Aun'Va backed his plan.

• Shadowsun watched human forces deploy and mourned the destruction of Deadwind's storms.
• Aun'Va arrived, absolved Shadowsun of blame for the failed expansion, and promised a path to victory in Mugula Gulf.
• Aun'Va introduced Director Eternal Explorer, whose presence gave Shadowsun an unexplained sense of death.
• Eternal Explorer proposed using Warp transmitters to create a one-way spatial barrier that would stop Imperial ships crossing Damocles Gulf.
• Shadowsun warned that the Imperium had powerful new forces and might understand its technology better than they believed.
• Eternal Explorer dismissed her concerns, claiming the Imperium relied on inherited relics and could not understand its own Warp engines.

Shadowsun and Aun'Va visited Yongtan’s secret underground research institute, where he promised to reveal a weapon that could help hold Mugula Gulf. As Yongtan plunged the facility into darkness, Aun'Va considered the collapse of the Third Sphere Expansion and the horrors reported by the eastern fleets.

• Aun'Va rebuked Shadowsun for her fear and led her to a fortified Orca transport carrying her to the hidden institute.
• Yongtan revealed that builder drones and Gusavi had constructed the facility, and Shadowsun learned the Gue'vesa workers had been killed to keep its location secret.
• Shadowsun accepted Aun'Va's justification that the Gue'vesa had died for the Greater Good, though Yongtan appeared thoughtful as they repeated the phrase.
• Shadowsun saw an automated factory filled with glass pods, but Yongtan redirected her toward the secret weapon.
• Yongtan extinguished the lights to demonstrate a surprise, startling Shadowsun and putting the Honour Guard on alert.
• Aun'Va recalled reports of the failed Third Sphere Expansion, including an eastern fleet's fearful final message about colossal monsters and darkness.

The T'au Empire faced setbacks on its eastern and southern fronts while Aun'Va suppressed news of Shadowsun's defeat and placed his hopes in Director Yongtan's research. Yongtan unveiled thousands of prototype Astartes warriors called Reflections, which Aun'Va assigned to Shadowsun as the T'au prepared for war.

• The eastern fleet appeared to have suffered a disaster, while Ork fleets drove the southern expansion force back and forced the region into a wartime economy.
• The northern fleet discovered mysterious Blackstone, but Earth Caste engineers could neither study nor mine it.
• After learning of Shadowsun's crushing defeat, the Ethereals suppressed the news, cut consumer goods production, and trusted the Earth-Xiaowake Research Institute's claim that it had developed a decisive weapon.
• A silver-white armored giant appeared before Shadowsun and the Honor Guard, then knelt and pledged loyalty to Aun'Va.
• Director Yongtan revealed thousands of AI-integrated warriors equipped with jump packs, Rotary Ion Scatter Cannons, and Thermal Knives, and named them Reflections, the Shadows of Damocles.
• Aun'Va assigned the Reflections to Shadowsun's command and ordered Yongtan to produce more warriors.

Yongtan harvested gene-seed from captured Raven Guard and refined his plans for an army built from viruses, gene-seed, and T'au biology. He discovered that T'au traits could shield his Annihilation Virus subjects from Warp corruption, leaving him eager to exploit the T'au Empire once the Damocles Gulf was sealed.

• Yongtan had Reflection Warriors hold captured Raven Guard while he extracted their gene-seed, killing them in the process.
• Yongtan reviewed his experiments and found that T'au genetic traits helped prevent the Annihilation Virus from succumbing to Warp corruption.
• Yongtan watched Z-99 obey him without the instability seen in subjects from other species.
• Yongtan planned to harvest T'au and combine their traits with viruses and Space Marine gene-seed to build a vast army.
• Yongtan examined a mutilated T'au head for signs of hatred, then fed it to a degraded form.

Shadowsun worried that the Reflection Warriors were becoming more like autonomous weapons than T'au soldiers, even as their numbers and combat success grew. She planned a concentrated counteroffensive at Mugula Gulf and ordered them to help encircle Commissar Cain and the 37th Regiment.

• Shadowsun questioned whether the Reflection Warriors, who had suffered seventeen casualties but left no remains, could still be considered T'au.
• A Xiaowak Researcher told Shadowsun that Director Yongtan would send more Reflection Warriors, bringing the available force to three thousand.
• Shadowsun proposed breaking through the Imperium's lines and driving its First and Second Armored Groups and attached Astra Militarum regiments into the New Storm Cluster.
• After learning that the Earth Caste had cracked human communications, Shadowsun planned to use an attack on Ciaphas Cain to draw in nearby Imperium forces.
• Shadowsun ordered a major counteroffensive for the following week and directed the Reflection Warriors to help encircle the 37th Regiment and capture Cain if possible.

Lin Fan prepared for the T'au Empire's counteroffensive while worrying that the early appearance of Reflections would provoke the Space Marines to invade. As Shadowsun's assault squad began its attack, she spotted the 37th Regiment's conspicuous banner.

• The T'au disabled Imperium monitoring with interference waves and blinding New Light Missiles as Shadowsun's assault squad flew toward the 37th Regiment.
• Shadowsun spotted the 37th Regiment's unusual red banner amid its fortifications.

Shadowsun led a T'au battlesuit assault against the Imperial defenders while Rebecca struggled to break through the upgraded electronic defenses. Lin Fan and the White Scars inflicted heavy losses, and the chapter left Kor'sarro Khan facing a mysterious black figure that emerged from the air.

• Shadowsun ordered her battlesuits to find and capture Commissar Cain as the T'au attack struck the 37th Regiment's bunkers.
• Rebecca's crash-loop code was blocked by Yongtan's unfamiliar anti-interference system, forcing Lin Fan to handle the battlesuits directly.
• Lin Fan smashed an XV8 Battlesuit and drove the nearby battlesuits into an emergency retreat.
• Kor'sarro Khan and the White Scars attacked Shadowsun, whose fusion blast destroyed a bike after a shield drone deflected Khan's first strike.
• Khan sensed a greater danger, fired at Shadowsun, and turned to slash at a black shadow that suddenly appeared before him.

Kor'sarro Khan, Lin Fan, and Rebecca fought strange Reflection Warriors that contained twisted creatures beneath T'au skin, while Tech-Priest Delia arrived with reinforcements. Delia sent her mechanical dog Alpha toward the 37th Regiment's front line as Rebecca remained uncertain what the creatures were.

• Kor'sarro Khan's force was disrupted by shadow warriors while Shadowsun's battlesuit troops recovered and counterattacked.
• Rebecca discovered that Reflection Warriors contained tortured creatures bound inside T'au skin, and saw their bodies recover after she struck them with electricity.
• Tech-Priest Delia arrived and destroyed a Reflection Warrior, while Rebecca saw its bound flesh vanish completely.
• Delia told Rebecca that she had brought Selina, Kastin, and Cain, and Rebecca explained that Soap had charged ahead while Erika and Old Jock held the front line.
• Delia sent Alpha, transformed from her rocket engines into a mechanical dog, to check the 37th Regiment's front.

Commissar Cain’s forces regrouped and attacked the Mirror Soldiers guarding the black sphere, while the battle inside remained obscured. The fighting continued without fleet support, and Cain faced a Mirror Soldier in close combat as Jurgen covered him.

• Delia retrieved battlefield footage from her mechanical dog, revealing the black sphere and the Mirror Soldiers collecting the fallen.
• Cain learned that the Valhalla battalion had over fifteen thousand combatants and the Penitent Army had around eight thousand, but Rebecca said they could not contact the fleet and suspected Aeldari involvement.
• Cain ordered Kastin and Selina to deploy their forces, and Valhallan mortar crews bombarded the Mirror Soldiers around the sphere.
• Selina led the Penitent Army into the attack, while the Valhallans used coordinated mortar fire to crack a Mirror Soldier’s armor and bring him down with bolt rounds.
• Cain fought a Mirror Soldier with a Shattered Sacred Sword and struggled to keep pace until Jurgen’s sniper round struck the enemy’s helmet.

Cain fought the Reflection warriors alongside Delia and Jurgen, while Selina recovered from devastating injuries through her strange regenerative power. The battle continued with Cain realizing his companions were more formidable than he had thought.

• Cain wounded the Reflection with his sacred sword, but the warrior knocked him down and fired at him until Delia intervened, killing another Reflection and driving into the enemy ranks.
• Selina was thrown into Cain's arms with severe injuries, then told him to hold off the charging Reflections while she caught her breath.
• Cain called for Jurgen's help as he fought several Reflection warriors, and Jurgen drove his motorcycle into them before killing them with his meltagun.
• Jurgen offered Cain Tanna tea, and Cain was startled to see Selina healed and energetic again.
• Selina explained that her regenerative power had awakened after a near-death injury and that she managed its excessive growth by regularly injuring herself.

After Rebecca threw Jurgen into the expanding black sphere, his presence ruptured it and released the trapped souls. Lin Fan treated the corrupted survivors while explaining the sphere’s origins to Cain.

• The battle against the Reflection Warriors ended with more than seven hundred Valhalla and Penitent Army soldiers dead, and medics used Lin Fan’s Gold Kela and Selina’s blood to treat the wounded.
• Rebecca realized Jurgen’s blank nature might affect the black sphere, then threw him into it after he agreed to serve The Emperor.
• Jurgen tore open the sphere, releasing wailing black souls that passed harmlessly through Cain and the other soldiers.
• Cain and the others found Lin Fan slapping wounded humans and T'au awake to cleanse their Warp corruption.
• Lin Fan explained that the shadows had absorbed the battlefield’s dead and formed the sphere that engulfed the frontline forces.

Lin Fan, Kor'sarro Khan, Erika, and their forces fought off reflections and Warp horrors after the disruptor opened a rift into the Formless Wastes. Director Yongtan revealed that he had activated the disruptor to block the Imperium from crossing the Damocles Gulf and showed Shadowsun the tortured Aun'Va and captured warriors.

• Lin Fan ordered Erika to keep the Krieg troops with Old Jock as shadows engulfed the battlefield and attacked the soldiers.
• Kor'sarro Khan rallied the White Scars while lightning struck fleeing T'au battlesuits and the sky revealed the Formless Wastes.
• Lin Fan slapped Shadowsun out of her terror, then he and the others fought reflection soldiers emerging from the vapor columns.
• Lin Fan struck reflections into the black barrier, causing the Formless Wastes projection and the flow of new reflections to vanish.
• Director Yongtan appeared on a screen and told Shadowsun he had activated the disruptor to stop the Imperium crossing the Damocles Gulf.
• Director Yongtan showed Shadowsun the tortured Aun'Va and revealed that her battle-brothers were in his laboratory.

Lin Fan stopped Kor'sarro Khan from attacking Shadowsun and used an Aquila mark to reveal their connection, convincing the Khan to listen to him. Kor'sarro and Lin Fan then marked the other White Scars, who accepted Lin Fan as their uncle.

• Space Wolves and Raven Guard fought the flesh-crafted reflections while Yongtan watched and celebrated their growing hatred.
• Kor'sarro Khan attacked Shadowsun, but Lin Fan intervened and defeated him in a brief clash, stamping an Aquila mark on his forehead.
• Kor'sarro recognized Lin Fan, performed a Chogoris rite, and agreed to listen after Lin Fan promised him a book as a token.
• The White Scars mistook Kor'sarro's actions for betrayal, so Lin Fan and the Khan subdued them and marked their foreheads.
• The White Scars accepted Lin Fan and apologized to him in unison.

Lin Fan freed the T'au captives and ordered Kor'sarro Khan and Cain to rescue survivors while he prepared to confront Director Yongtan. The White Scars accepted Lin Fan as their Uncle and were left poring over a motorcycle book they believed Jaghatai Khan had written.

• Kor'sarro Khan and the White Scars swore loyalty to Lin Fan after the Great Khan called him Jaghatai's brother and told them to obey him.
• Lin Fan ordered the warriors to bring him Warp-corrupted soldiers so he could slap them back to sanity, while Shadowsun gathered the surviving T'au pilots.
• Jurgen's untouchable nature destroyed the black sphere, allowing Cain and his group to reach Lin Fan's party.
• Shadowsun identified Director Yongtan as the creator of the Reflection Warriors and vowed to kill him, adding him to Kor'sarro Khan's hunting ledger.
• Lin Fan gave Kor'sarro Khan a motorcycle repair book, sent Cain to search for survivors, and ordered the White Scars to rescue troops on the other front lines.
• Kor'sarro Khan and the White Scars recognized the book as Jaghatai Khan's work and became absorbed in reading it.
