A silent journey unfolds beneath a city that no longer sees the sun. The passengers, shrouded in garments that speak of a world upended, are the remnants of a society that danced too close to the precipice of its own making. There's a rhythm to their travel, a cadence that echoes the heartbeat of a world now out of time. The train, once a vessel of bustling life and noise, glides through the darkness, a serpent in the bowels of a dying earth. Its occupants are the keepers of stories untold, each a guardian of the last vestiges of hope in a realm where hope has become a currency as rare as the light they yearn for. They do not speak, for their mission is one of quiet resistance, a defiance against the end of days. The journey is long, and the destination uncertain, but they ride, each with their own vigil, a silent oath to preserve the flickering flame of humanity's legacy.
