The Last Alchemist TrainChapter Archive

The Bridge That Remembered

The first morning

Oliver began the Alchemist Train’s journey from Marrow Station and discovered that its emotional fuel was already sinking toward grief. Nadia, an exiled princess with a volatile anti-gravity core, forced her way into the engine cab just before they reached a broken bridge, where the mysterious Horologist appeared and claimed the train was early for its last departure.

The Weight of a Name

Minutes after the broken bridge

The Alchemist Train crossed the broken bridge through open sky, aided by Nadia’s unstable core and Oliver’s desperate control of the failing stabilizer fuel. The Horologist reappeared inside the engine and revealed that they were climbing toward the place where gravity was first taught to kneel. Nadia’s core alerted an unseen power, and a faceless black train rose from below to intercept them.

The Train Beneath the World

The next hour

The black train drew alongside the Alchemist Train and revealed visions of emotions it had consumed, including an older version of Oliver who warned him not to reach the source. When the trains collided without impact, Nadia’s core cracked open the fuel gauge and transformed its reading into HUNGER. The Alchemist Train reached the underside of the upper continent, where an inverted tower awaited them; the Horologist revealed that it was where Nadia’s heart had been made.

The Door That Weighed Nothing

A few minutes later

Oliver and Nadia entered the inverted tower, where they found a vast heart-like machine connected to abandoned trains and discovered that Nadia’s core was part of a larger construction. The machine revealed that Oliver’s name was carved into its engineer’s seat and demanded the return of stolen weight, while the Alchemist Train released the memories it had gathered and the fuel gauge changed from HUNGER to DEBT.

The Weight of Returning

That same moment

The heart-machine revealed that the Alchemist Train had not transformed human emotions into fuel but had stolen and stored them as a debt supporting the failing gravity of the world. Oliver learned he had been the first keeper of this borrowed system, while Nadia discovered that breaking the machine would return the weight but might cause everyone sustained by the debt to fall.

The Burden of Everyone

That same minute

The Horologist revealed that Oliver had created the original gravity bargain and that the machine’s stolen emotions had been sustaining the world through an ever-growing debt. Oliver and Nadia were offered two terrible choices: return all the stolen feeling at once and cause catastrophic gravity, or divide the burden among every living person. Oliver reached for the second option, but the heart-machine claimed he had already made this choice once, while something vast approached the sealed tower.

The Passenger Made of Weight

The next few minutes

The heart-machine revealed that CARRY required returning stolen emotions to their original owners by name, rather than forcing one person to bear the debt. Nadia and Oliver began releasing individual feelings, but the approaching faceless entity—formed from Oliver’s original refusal to face the burden—breached the tower’s sealed door. Oliver then discovered that one of the threads bore his own forgotten name.

The Name Beneath the Name

That same hour

Oliver reclaimed his forgotten surname and confronted the faceless keeper as the abandoned part of himself. By naming and witnessing Oliver Vale, with Nadia and the Horologist joining him, the machine briefly restored gravity and transformed the entity into a recognizable person—but the black sphere revealed that one final name was still withheld.

The Name of the Train

The same moment, continuing through the tower’s collapse

Gravity returned only briefly before the tower resumed its fall, and the transformed remnant of Oliver revealed that another name had been withheld. The Horologist finally disclosed himself as Aven Marr, the first passenger who helped normalize the original bargain, but the machine still marked its owner as unknown. The Alchemist Train crashed into the tower, and Oliver heard the long-forgotten name of the train: Mercy—followed by three knocks from someone inside its engine.

The Passenger in Mercy

Moments after the crash

Oliver opened Mercy’s engine and found an impossible station containing the stored, unnamed emotions taken by the train. A masked remnant revealed that Queen Seris, Nadia’s mother and the first owner of the core, had withdrawn her consent and begged Oliver to save someone before he departed; the machine’s unknown owner was tied to that withheld mercy.
