Chapter Summaries

After the Emperor helped clear a route through the Warp Storm, Romulus, Ramesses, and Arthur discussed how Arthur’s presence let the Emperor communicate normally and considered how to use the Soul Circuit. They then planned the fleet’s search for T'au worlds, but the T'au’s faint Warp presence made prophecy useless and forced them to look for allied species.

• Romulus received word that the Warp Storm near Tigrus was subsiding and that the Navigators had found a clear passage.
• Ramesses suggested that Arthur’s traits allowed a more human Emperor personality to speak through the Black Sword, and asked Arthur to spend time around the Sisters and Astartes to recharge it.
• Ramesses considered using the Soul Circuit to amplify Warp energy and connect a Psyker-linked collective to another Psyker presence.
• Romulus reviewed the T'au Empire’s star map and noted that the fleet could make only three more jumps before reaching Dal'yth.
• Ramesses concluded that the Transmigrators could not use Aeldari prophecy to locate T'au worlds and would have to search for the T'au’s allied species instead.

Arthur reviewed the growing number of Fallen Angels and Alpha’s recruitment proposal while the fleet prepared to find a T'au world with a Slipstream Module. After Karna recalled Bork'an’s history, Ramesses found its coordinates, and Romulus ordered the fleet to depart after resupply.

• Arthur noted that five hundred Fallen Angels had responded and scrutinized Alpha’s complicated, partly Chaos-aligned force and its neophyte recruitment plan.
• Hydra brought documents to Arthur’s office after proposing that Alpha recruit neophytes through the Expeditionary Fleet.
• Karna joined Romulus and Ramesses as they searched for a T'au planet, then suggested Bork'an, the former homeworld of the Nicassar.
• Ramesses used the Warp to locate Bork'an’s coordinates and passed them to Romulus.
• Romulus ordered the Navigators to plot routes and scheduled the Expeditionary Fleet to set sail after thirty-nine Terra hours of resupply.

The Expeditionary Fleet attacked the T'au defenses at Bork'an, broke through the planetary fleet, and began a boarding operation to seize Slipstream Module technology and a star map. As Carcharodons teleported into the Star Fortress, Kahurangi and the Aeldari mentors continued their risky psychic training, with one Farseer apprentice deciding to keep teaching for the promised rewards.

• Romulus ordered the Expeditionary Fleet to seize the flank after Dawn detected the T'au fleet and orbital fortresses at Bork'an.
• The T'au defenses attacked with Particle Cannons and AI-guided missiles, but the Imperium fleet's Void Shields absorbed the barrage.
• The Expeditionary Fleet accelerated into the T'au formation and destroyed much of the planetary defense fleet at close range.
• Ramesses's psychic interference corrupted the Star Fortress's systems, and Romulus ordered a boarding operation to capture technology and intelligence.
• Ledodus deployed the Black Templars, while Kahurangi used Aeldari-guided teleportation to place thirty-nine Carcharodons inside the Star Fortress.
• The Farseer apprentice struggled with teaching Astartes but chose to continue for the chance to earn more living space.

Tyberos and the Carcharodons stormed the T’au Star Fortress, guided through its defenses by Kahurangi and the Farseer Apprentice, and slaughtered its defenders. The fortress broke apart and fell toward the planet, where an Earth Caste girl mistook the burning wreckage for a meteor.

• Kahurangi relayed the route as Tyberos led the Carcharodons through the fortress, killing T’au defenders while the Farseer Apprentice guided them past strongpoints.
• The fortress commander learned that the defenses had failed, the diplomatic vessel had been destroyed, and communications were down.
• Captain Zhuo Yuan urged the commander to escape and warn the Ethereal, but the Carcharodons burst into the command room and massacred the defenders.
• The Carcharodons left the Star Fortress in ruins as warships and Crimson Lances tore through it.
• The shattered fortress fell through the atmosphere, and an Earth Caste girl pointed it out to her teacher as a meteor.

Romulus and Cawl discussed how human choices, rather than AI or xenos themselves, caused the Imperium’s worst disasters while Astartes seized Bork'an's homeworld. Romulus rejected the idea of uniting with the Tau, recognizing that their expansionism and the Imperium’s brutality made conflict inevitable.

• Romulus explained that the assault advanced quickly because Tau evacuation efforts diverted manpower from the defense.
• Romulus and Cawl concluded that people were the fundamental source of danger, and discussed how the Emperor’s long wars on Terra had been shaped by humanity’s misuse of forbidden technology.
• Romulus praised Cawl for retaining his principles despite immense power and wealth, and Cawl warned that the Tau might not be suitable allies.
• Romulus rejected the notion of joining the Tau, citing their espionage, support for rebellions, and absorption of human worlds.

Romulus’s forces conquered Bork’an, recovered its technology, and destroyed the T’au homeworld with Cyclonic Torpedoes before advancing toward Dal’yth. Farsight conceded defeat and abandoned the colonies, while Romulus’s team gathered evidence that better living conditions reduced Chaos corruption; after the Governor’s Palace operation, Romulus prepared to deal with Inquisitor Rost.

• Romulus explained to Cawl that humanity needed to learn from other civilizations and offer people a better future, then received Arthur’s report that Bork’an’s technology, scientists, and Votann artisans had been secured.
• Romulus ordered the fleet to leave Bork’an and strike the T’au homeworld with Cyclonic Torpedoes instead of heading to Dal’yth.

• Farsight ordered the T’au to abandon the colonies and evacuate their populations while he led the Fire Caste to hold the rear.
• Romulus and Drakus compiled evidence that improved living standards reduced Chaos corruption and concluded that replacing corrupt rulers was preferable to punishing the population.

• Romulus read the battle report detailing the destruction of Imperial forces at Dal'yth and the Punishment Fleet's failures under Inquisitor Rost.

The Wings of Dawn coordinated the campaign to reclaim Ultramar’s eastern sector while Romulus, Karna, and Ramesses discussed the Astral Claws’ support network and plans to handle captured Alpha. On Calth, Inquisitor Aglaia and the Transmigrators met Lufgt Huron, with Aglaia recognizing a possible irregularity involving the Tiger Claws.

• The Wings of Dawn remained together and headed for Calth to direct the effort to reclaim Ultramar’s eastern sector.
• Karna told Romulus that Huron’s Astral Claws and the Mortifactors had established a support network, and reported that Space Wolves had beaten an Alpha prisoner until Arthur saved him with Primaris surgery.

• Huron welcomed Romulus and his companions, impressed by their achievements and hoping to secure their support for his plans in the Maelstrom.
