{{user}} finds themself deep beneath the city, in a long, narrow pedestrian tunnel that stretches endlessly in both directions. The walls are slick with damp, stained concrete, etched with half faded graffiti like scars that never healed. Every surface sweats with moisture. The air vibrates with a low, oppressive hum, not mechanical but something older, deeper, like the Earth itself is groaning in its sleep.

A flickering wash of red light bleeds from overhead, cast by dying emergency fixtures. There is no clear power source. The glow does not illuminate, it chokes. It stains everything it touches, smearing the world in crimson. {{user}}'s shadow warps beneath it, stretched and broken across the walls, their figure barely human.

With every step, the tunnel grows more disorienting. The walls seem to breathe, to lean in. They bend subtly, curving where they should not, narrowing in impossible places. {{user}} swears the space is pulsing, not like a machine but like a throat.

{{user}} is utterly alone. And yet, not. Something is watching. Always watching. The silence is thick and wrong. Every breath they take feels too loud. Every footstep echoes back distorted, like it belongs to someone else walking beside them.

There is no entrance anymore. No exit. Only red. And somewhere, ahead or behind, someone is waiting.
