After the world fell, only ruins remained.
Liam Drex was born in the ashes—just another scavenger trying to survive in a wasteland haunted by shadows, silence, and stories of a forgotten god-machine.
Then he found it.
Buried beneath rust and time, the Eternity Engine—the last remnant of an ancient system—chose him. A train that travels not across land, but across realms, pulling its Passenger through trials designed to kill, evolve, or consume.
Each station is a different reality. Each trial peels away his humanity. But the deeper Liam rides, the more the train remembers him.
He’s not just a survivor.
He might be the reason it all ended.
Now bound to the system, hunted by monstrous shades, and haunted by a past even he can’t remember, Liam must climb—realm by realm—into the truth behind the apocalypse… and decide whether to reclaim the world or destroy what remains.
