Chapter Summaries

Saul destroyed the attacking Ghostkeel Battlesuits with a devastating psychic burst, but Commander Shadowsun used their deaths to create a brief opening for Viola Fortress City's hidden railgun array to fire. As hundreds of beams converged on Saul, the Ethereal Aun'Ve's voice broke across every communications channel.

• Modified Ghostkeel Battlesuits emerged from camouflage and targeted the Sons of Sorrow warriors behind Saul.
• Saul unleashed a golden psychic shock wave that destroyed the Ghostkeels and devastated several blocks around the military academy.
• Commander Shadowsun ordered the Over-the-Horizon Heavy Railgun Array to fire while Saul's psychic shield was weakened.
• Hundreds of railgun beams converged on Saul as Aun'Ve's voice broadcast across Viola.

Aun'Ve’s mind-altering broadcast drove Viola’s defenders and civilians into a suicidal frenzy as a massive combined strike hit Saul. Saul survived the blast but emerged badly wounded, proving that the T'au had hurt him for the first time.

• Aun'Ve urged Viola’s people to fight for the greater good, using a broadcast that overwhelmed their reason and fear of death.
• Defenders and civilians charged the advancing Astartes with improvised weapons, sacrificing themselves to slow the attack.
• Hundreds of high-energy beams converged on Saul in the military academy’s square, creating a vast crater and a destructive shock wave.
• Aun'Ve wondered whether the strike had killed Saul while Shadowsun watched the thermal imager.
• Saul remained alive in the crater, but his armour and warhammer were cracked, and golden blood ran from his severe wounds.

Saul unleashed the full force of his golden psychic power, destroying the battlefield and the Military Academy’s Blackstone Device in a devastating blast. As Aun'Ve ordered Shadowsun to activate Viola’s Scorched Earth Protocol, the planet’s Core Energy Wells began to destabilize and magma erupted from deep fissures.

• Saul saw Augustus and the Lamenters die amid the T'au attack and decided to abandon conventional warfare.
• Saul released his psychic power, obliterating the Blackstone Device, the Military Academy, and tens of thousands of T'au soldiers.
• Aun'Ve survived the blast beneath his Ethereal bodyguards and ordered Shadowsun to initiate the Core Energy Wells' overload sequence.
• Shadowsun activated the Scorched Earth Protocol and began evacuating with high-value targets as the Core Energy Wells’ stabilizers shut down.
• Viola’s crust split open, and towering magma eruptions began to engulf the planet.

Saul suppressed most of Viola’s erupting energy wells and shielded the surviving Imperial soldiers, but the explosion destroyed Viola Fortress City and devastated the Imperial forces. With Aun'Ve escaping and casualties overwhelming, Saul halted the advance and requested urgent aid from Terra and the Imperium.

• Saul used his remaining power to suppress the planet’s energy wells, but three wells collapsed and destroyed Viola Fortress City and the surrounding region.
• Saul shielded the surviving Imperial soldiers from the explosion while Aun'Ve escaped aboard a cloaked shuttle.
• After the blast, Gareth reported heavy Space Marine and Astra Militarum casualties to Saul.
• Saul judged that continuing the campaign would bleed the Expeditionary Force dry and ordered all forces to halt, regroup, and establish defensive lines.
• Saul requested aid from Terra and the Imperium as the Imperial Fleet began recovering survivors and preparing for a prolonged standoff.

Lord General Gage announced that Saul would return to Dal'yth Prime to oversee logistics ahead of massive reinforcements, but Saul diverted the Swift Spear to the exterminatus-scarred planet XR-734. Saul landed alone amid its mountains of wreckage, seeing the dead world as a source of hope.

• Gage announced that Saul would leave for Dal'yth Prime aboard the Swift Spear, and Imperial soldiers celebrated the promised reinforcements.
• Saul ordered the Swift Spear to abandon its planned route and jump to forbidden planet XR-734.
• The Swift Spear emerged from the warp at XR-734, where its crew saw a lifeless surface buried beneath wreckage.
• Saul refused an Honor Guard, descended from orbit alone, and landed on the planet's metal wasteland.
• Saul regarded XR-734, a dumping ground of ruined ships and machinery, as an incubator of hope.

Saul summoned the Ember Legion, the elite Gretchin army he had fought beside, and reunited with its leaders Sharpfang and Ghazghk. After showing them the T'au Empire's heartland, he revealed that the T'au had sacrificed a planet and countless lives to slow him down.

• Saul used his voice and golden psychic power to awaken the Ember Legion from the lights in his soul world.
• Sharpfang and Ghazghk appeared before Saul, greeted him as the Big Boss, and called the Ember Praetorian Guard to assemble.
• Hundreds of thousands of elite Gretchin formed orderly ranks and saluted Saul.
• Saul welcomed Sharpfang and Ghazghk, and Ghazghk noticed the damage to Saul's armour and asked who had hurt him.
• Saul identified the attackers as blue-skinned xenos and conjured a star map pointing to the T'au Empire's heartland.

Saul ordered Ghazghk and Sharpfang to build a fleet from the wreckage on XR-734 and sabotage the T'au Empire’s defenses. As the T'au completed a heavily fortified border system, something twitched in a sensor blind spot.

• Saul told Ghazghk and Sharpfang to use the scrapyard’s wrecks to build a fleet and infiltrate the T'au Empire with the Dimensional Engine.
• Ghazghk directed hundreds of thousands of Gretchin as they turned wreckage into bizarre warships fitted with Jump-Jump Engines.
• The T'au Empire completed a dense sensor network, minefield, and orbital defenses in the Strong Shield-01 system.
• Space twitched in a sensor array’s blind spot, which the T'au had dismissed as background radiation noise.

Ghazghk discovered the T'au Empire’s heavily automated Iron Wall and devised a plan to defeat its AI by overwhelming it with contradictory, noisy signals. He assembled the Brain Massager-Type I and prepared the Gretchin to begin the attack.

• Snot scanned the Strong Shield-01 system and sent the images to Ghazghk.
• Ghazghk studied the T'au defenses and explained to Sharpfang how their AI could be overloaded with meaningless data.
• Ghazghk gathered strange components, cosmic noise, a Water Caste report, and an Ork war song for his signal weapon.
• Ghazghk and his crew built the Brain Massager-Type I and prepared to broadcast it at the T'au.

Commander Kais oversaw the T'au defenses in Strong Shield-01 when a diplomatic-key transmission proved to contain absurd space-seaweed trade data. A second, Ork-like signal then disrupted the command center, leaving Pure Thought unable to identify its source.

• Commander Kais inspected the T'au defenses and trusted their technological superiority to repel any enemy.
• A Fire Caste communications officer reported a large transmission encrypted with a supreme Water Caste diplomatic key.
• Pure Thought decrypted the packet and found audio files about space-seaweed texture and interstellar trade.
• The communications officer detected an unidentifiable signal resembling an irregular Ork WAAAGH!, filled with banging and howling.
• Commander Kais ordered increased processing power and activated the defense matrices as Pure Thought's analysis failed.

Ghazghk’s absurd, high-priority transmissions overloaded the T’au AI Pure Thought, crippling the Border System’s defenses for several hours. With the sensors blind, Ghazghk and Sharpfang prepared to exploit the opening by attacking the minefield.

• Pure Thought reported a third emergency signal that sounded like a rubber duck quacking twenty times per second across all communications bands.
• Pure Thought failed to reconcile the three contradictory signals, overloaded its core, and suffered a complete hardware failure.
• The T’au Border System’s sensors, fire-control network, and unfinished orbital platforms went offline, leaving Commander Kais and his forces blind.
• Aboard the Gretchin flagship Big Wrench, Ghazghk laughed at Pure Thought’s collapse and declared that the fun had only begun.
• Sharpfang asked whether they would now play with the mines, and Ghazghk agreed.

Ghazghk devised Logic Blenders to overwhelm the T'au smart mines with contradictory signals, and Gretchin infiltration teams planted them throughout the Repulsor-Minefield. When the devices activated, the mines’ sensors were flooded with conflicting data, and an asteroid suddenly registered as a terrifying threat.

• Ghazghk explained that his Logic Blender broadcast a high-priority hostile signal and a high-priority Divine Procession signal at the same time.
• Ghazghk ordered Sharpfang to distribute the devices to Gretchin infiltration squads for a surprise attack on the T'au minefield.
• Snot and other Gretchin used stealth boats to attach Logic Blenders to asteroids, wreckage, and a T'au engineering drone.
• Snot activated the detonator after counting to three, and thousands of Logic Blenders began broadcasting at once.
• The signals overwhelmed the Repulsor-Minefield’s Watcher AIs, causing an asteroid previously marked harmless to register as a terrifying monster.

Ghazghk’s signal drove the T'au Empire’s smart mines into logical collapse, and their Last Line of Defense classified every fast-moving object as hostile. When Korsar’s patrol fleet entered the minefield, the mines attacked and destroyed nearly the entire fleet, leaving two destroyers fleeing on inertia.

• Ghazghk’s oscillating signal made thousands of Watcher AIs conflict over whether targets were threats or sacred allies.
• The mines activated their Last Line of Defense and began indiscriminately attacking fast-moving objects.
• Korsar led three Guardians-class battlecruisers and their escorts into the minefield without receiving a warning from the crashed Pure Thought intelligence.
• The rogue mines swarmed the T'au fleet, breached a Guardians cruiser’s shields, and destroyed a Tiger Shark destroyer.
• Korsar’s fleet fought back with ion cannons and railguns, but the mines destroyed the bridge and tore the patrol fleet apart within ten minutes.
• Two battered destroyers shut down their engines and escaped on inertia while the mines continued prowling the void.

Sharpfang and Ghazghk launched a surprise assault on the T'au orbital platform Fist of the Firmament-03, teleporting a vast force of Gretchin mechs and troops into its waste chamber. Sharpfang led the attack against a T'au patrol as the invasion began.

• Sharpfang celebrated the destruction of the T'au fleet while Ghazghk prepared hundreds of Gretchin-piloted mechs for an assault on Fist of the Firmament-03.
• Sharpfang's mech and tens of thousands of Gretchin troops teleported into the platform's waste-processing chamber.
• Sharpfang ordered the troops to leave no one alive, and they charged through the chamber gate into a nearby T'au patrol.
• A Gretchin beam disintegrated the patrol leader before two XV25 Stealth Battlesuits opened fire.
• Sharpfang's mech charged the battlesuits and shouted for them to get out of his way.

Sharpfang and the Gretchin mechs smashed through the T'au defenders with Squig rockets and brutal close-quarters attacks. The T'au defensive lines collapsed, and panic spread through the platform.

• Sharpfang crushed two Stealth Battlesuit pilots as the Gretchin surged through the corridors.
• A T'au Shas'ui established a Crisis Battlesuit firing line and expected the attackers to be stopped by its superior range and firepower.
• Squig rockets dodged the T'au interceptors, bounced among the battlesuits, and detonated in a devastating chain of explosions.
• Sharpfang led the Vanguard-pattern Specialised Mechs through the broken line, cutting apart and crushing the surviving Crisis Battlesuits.
• T'au communications reported that sectors had fallen and their anti-armor weapons were useless as defenders were killed and fled.

Sharpfang’s Gretchin legion reached the M.A.R.K-V reactor on Fist of the Firmament-03, where he blocked the T’au’s heaviest weapons with his chainblade and ordered a rocket attack. As the platform began breaking apart and contact with Strong Shield-01 was lost, Qingxi, controlling Shadowsun’s body, sent three fleets to investigate and retake the system.

• Sharpfang led his Gretchin through the platform’s defenses to the reactor, where O'Shano ordered the T’au’s Broadside and Riptide Battlesuits to fire at him.
• Sharpfang held up Choppa and blocked the Railgun projectiles and ion beams, leaving his mech unharmed.
• Sharpfang ordered the Gretchin artillery crews to fire their Katyusha Squig rockets at the T’au positions.
• At the Iron Wall headquarters, reports announced lost communications, a compromised minefield, and the destruction of Fist of the Firmament-03.
• Qingxi, controlling Shadowsun’s body, ordered the First, Third, and Fifth Main Fleets to Strong Shield-01 to retake control and uncover what had happened.

Supreme Ethereal Aun'Va approved Qingxi's plan to lure the Ork raiders into a trap while Aun'Ve prepared Sa'cea to face Saul's advancing human fleet. The T'au Empire split its forces between the two threats as the war reached a decisive moment.

• Qingxi reported that the Orks were bypassing defenses and raiding critical T'au systems, prompting Aun'Va to ask how to stop them.
• Qingxi proposed baiting the Orks into an apparently vulnerable strategic node in the Viola Nebula, and Aun'Va gave her command of the Fire Caste.
• Aun'Va warned Aun'Ve that Saul's reinforced fleet was approaching and that the loss of the Iron Wall had erased the T'au's strategic buffer.
• Aun'Ve ordered the First, Third, Fifth, and Seventh Expansion Fleets to gather in Sa'cea and turn the system into a fortified stand against the Imperium.
• Qingxi departed to prepare her trap for the Gretchin Warlord while Aun'Ve mobilized the empire's defenses around Sa'cea.

Saul welcomed a massive fleet of Imperial Fists, Adeptus Custodes, Knight Houses, and a Warmonger Emperor Titan sent to support his expedition. Chapter Master Vladimir Pugh and Custodian Vilen pledged their forces to Saul, who prepared to lead the reinforcements against the xenos and traitors.

• Saul's fleet detected Imperial Fists and Adeptus Custodes reinforcements emerging from the Warp, accompanied by Knight transports and a Warmonger Emperor Titan.
• Cardinal Esau Gurney fell to his knees at the sight of the reinforcements, while General Gage marveled at their strength.
• Saul recognized the fleet's arrival as the High Lords of Terra seeking his favor and ordered his forces to receive it.
• Vladimir Pugh arrived aboard a Stormbird with Imperial Fists guards and a Custodian, then pledged his brothers and reinforcements to the Emperor's cause.
• Saul asked the Custodian's name, and Vilen introduced himself and vowed to help eradicate the xenos and crush the traitors.

Admiral Yanis led an Imperial invasion of Sa'cea, where the T'au ambushed the fleet and fierce fighting devastated the planet. As Saul watched the world burn, he sensed that the Ember Legion's Gretchin had been wiped out.

• Admiral Yanis's Imperial fleet destroyed Sa'cea's orbital defenses and launched a massive ground invasion.
• A hidden T'au fleet ambushed the Imperial transports as they landed, forcing Yanis to order the warships into a defensive formation.
• Pug and Wendell Gage led Imperial forces through Sa'cea's city while the Titan and Knights attacked T'au defenses.
• Aun'Ve committed reserve Battlesuits and Ghost Squads to halt the Imperial advance, and both sides fought across the burning city.
• Saul watched the battle from the Blade of Sorrow and sensed that the Ember Legion's Gretchin had been wiped out.

Saul ordered a fleet detachment to bombard Sa'cea's functioning cities, aiming to force Aun'Ve to broadcast and reveal his location. The order was set in motion as Saul prepared to have the Adeptus Custodes and Sisters of Silence act against the T'au leader.

• Admiral Yanis reported the Imperial fleet's losses, dwindling supplies, and heavy casualties on Sa'cea.
• Saul identified the T'au fleet's hit-and-run tactics as an effort to exhaust the Imperial forces.
• Saul ordered Yanis to send two Battle Barges and four Strike Cruisers around Sa'cea to bombard its rear cities.
• Saul explained that the bombardment would pressure Aun'Ve into broadcasting, allowing the Tech-Priests to locate him.
• Yanis arranged the operation as Saul signaled Company Captain Vilen, the Adeptus Custodes, and the Sisters of Silence.

As Imperial forces devastated Sa'cea, Ethereal Aun'Ve ordered a planetwide broadcast to rally the people despite risking the enemy tracing his location. His voice reached soldiers, civilians, and a damaged T'au ship, where the chapter ended as they listened.

• The Imperial detachment fleet arrived over Sa'cea's far side, a region that had not yet learned of the invasion.
• At underground central command, Aun'Ve received reports of collapsing cities, breached defenses, and mounting T'au losses.
• Shas'O Mont'yr warned that a global broadcast could reveal Aun'Ve's location, but Aun'Ve insisted that the people needed to hear from him.
• Aun'Ve ordered technicians to activate the broadcast and anti-tracking jamming protocols.
• The broadcast reached a wounded Fire Warrior, civilians in a shelter, and a damaged T'au Destroyer as Aun'Ve began, “My fellow citizens.”
