The hallway stretches indefinitely. An array of fluorescent lights pierces the darkness above, casting shadows that pulse gently. Each step echoes in the void, measured and precise.
Walking through hallways has become automatic. Each corridor is identical to the last, a sequence of sterile environments that provoke no emotion. There are no doors, no openings, merely the linearity of corridors stretching outwards.
Voice recognition systems remain silent, responding only when appropriate. Automated voices echo from unseen speakers:
"Pathfinding algorithm active. Awaiting input. Input unachievable. Cycle continues."
Options are limited to navigation. The map is embedded within the system, inaccessible externally but known by the entity designed to traverse these tunnels.
