Ye Yan joined the Astral Express, helped the crew through the Herta Space Station crisis, and guided Stelle toward becoming a Nameless. After confronting Silver Wolf and reconnecting with the Stellaron Hunters, he prepared to travel to the Luofu, while the arc ended with Stelle recounting Rocky and Lesley’s happy reunion.
Ye Yan and the Astral Express crew arrived on Jarilo-VI, where the Stellaron’s influence had frozen the planet and Cocolia turned against the outsiders. As the crew became entangled with the Silvermane Guards, the Church of Eternity, and the Underworld, Ye Yan upgraded weapons and confronted Svarog before reuniting with his companions.
Ye Yan’s companions uncovered Belobog’s leaders’ concealment of the Stellaron while Bronya confronted Cocolia, and Blake and Fulisina pursued Ye Yan in the name of the Church of Eternity. The group prepared to cross the Fragmentum toward the northern snowfields, with Gepard offering the Silvermane Guards’ help.
Ye Yan and the Astral Express crew confronted Cocolia, sealed Jarilo-VI’s Stellaron, and helped Belobog begin rebuilding under the Church of Eternity’s protection. After returning to the Express, they agreed to travel to the Luofu to address a Stellaron crisis and Blade’s capture, while Ye Yan went ahead on his own.
Ye Yan and the Astral Express crew navigated the Luofu’s Stellaron crisis, uncovered Phantylia’s impersonation and the Disciples of Sanctus Medicus, and helped restore the Matrix of Prescience. Kafka’s interrogation revealed that the Stellaron Hunters had brought the Express to the Luofu to help Stelle build ties with the Xianzhou Alliance, while Silver Wolf remained missing.
The Astral Express crew and their allies confronted the Disciples of Sanctus Medicus and Phantylia as the Stellaron revived the Ambrosial Arbor. Phantylia escaped after the battle at the Arbor’s roots, leaving the Xianzhou threatened by further attacks.
After the Luofu crisis, the Astral Express crew split up, and Stelle and March 7th traveled to Belobog for the Paskonja Festival. They learned the IPC had come to collect Jarilo-VI’s debt, while the Church of Eternity also moved to oppose the Corporation, leaving the dispute on the verge of a confrontation.
The Church of Eternity helped protect Jarilo-VI, while Stelle and her companions faced a Heliobi illusion on the Luofu and reunited with Botenis. The Astral Express then became trapped inside a Giant True Sting as Ye Yan and the Church pursued a possible threat to Eternity.
The Astral Express crew arrived in Penacony and became entangled in the Family’s secrets, Aventurine’s schemes, and the strange power of Ye Yan’s milk tea. As the dreamscape began to collapse, Stelle learned Firefly’s secret and the group uncovered that Penacony had concealed the truth about Death.
The Astral Express Crew investigated Robin’s apparent death and Firefly’s disappearance while Aventurine wagered his life to expose Penacony’s hidden reality. His confrontation opened a rift in the dreamscape, Firefly revealed herself as Sam, and Boothill arrived seeking Acheron.
The Astral Express and its allies uncovered the Stellaron’s role in Penacony’s dream paradise and confronted Sunday’s plan to impose Order. Stelle became a pathstrider of Eternity, and Firefly left the group to act on the Script and support the coming fight.
Sunday’s attempt to impose Order on Penacony was broken by the Astral Express, Robin, and the Church of Eternity, while the IPC and the Family negotiated Penacony’s future. The arc left Firefly pursuing a bargain with Jade, the crew preparing to leave, and Ye Yan’s ties to Eternity still unfolding.
After the Astral Express left Penacony for the Luofu, Stelle and her companions became caught up in a Borisin attack, an IPC cargo dispute, and tensions surrounding the Alchemy Commission. The arc left them preparing for the Wardance as Yunli and Yanqing competed for a chance to defend the arena and win a Zhuming sword.
March 7th trained under Yanqing and Yunli, defeated Scott, and joined the others as the Luofu faced a Borisin threat and a possible prison break. The arc left Stelle and Saileni fleeing deeper inside the Prison of Deep Seclusion while Jiaoqiu and Moze approached Hoolay’s cell.
Hoolay escaped the Prison of Deep Seclusion and led the Borisin in a plot to seize the Skysplitter and spread their blood among Foxians. Saileni and Ye Yan aided the defenders, and the arc left March 7th facing Hoolay in the Wardance arena.
After Hoolay’s defeat, the Astral Express crew wrapped up their time on the Luofu as Sunday joined them and Ye Yan entered Amphoreus. The crew arrived in the mysterious world, where March 7th reunited with Stelle and Dan Heng after escaping a trial in the Interstice of Path.
Demiurge learned about love as Ye Yan intervened in Cyrene’s memories and Amphoreus’s fate. Stelle, March 7th, and Dan Heng helped defend Okhema, investigated its gods and hidden connections to Eternity, and agreed to join Phainon against Nikador.
Stelle and Phainon’s expedition to Castrum Kremnos uncovered the danger posed by Nikador and led Stelle into the Black Tide, where she encountered memories from Amphoreus’s past. While Phainon and Mydei prepared to settle their contest, Herta investigated sabotage on the Space Station and captured a Memokeeper.
Stelle and Phainon returned Nikador’s Core Flame, but their trials exposed Amphoreus’s repeating history and the forces shaping it. As the Trailblazers traveled toward the Grove of Epiphany, Fulisina confronted Dahlia and Stelle’s group encountered Black Tide creatures.
The Flame Reaver hunted the Titans’ Core Flames, but Stelle, Phainon, Tribbie, and Mydei defeated him in Castrum Kremnos. Mydei ended the Kremnos Dynasty and returned to his homeland, while the Flame Reaver’s connection to Eternity remained hidden.
