A haunting, eerie building with an inverted staircase structure that seems to defy logic. The stairs descend into darkness rather than leading upwards, giving a sense of spiraling deeper into the unknown. The stairs are narrow and the edges are cracked, with a cold, metallic sheen that reflects the dim light flickering overhead. Each step feels unstable, and the sound of footsteps echoes unnervingly, even though no one else is present. The stairs are surrounded by walls that seem to shift as you move, making it hard to tell if you’re going up or down. At each landing, doors appear, but they open only to reveal more darkness, as if there’s no escape. The building’s walls are made of a reflective material, distorting your reflection into something unfamiliar. The faint flickering lights seem to fade as you approach, leaving you in total darkness for moments at a time. The deeper you go, the more you feel a creeping sense of being watched, as if unseen eyes are following your every movement. At the very bottom, the staircase ends abruptly, leading into an impenetrable void, and no matter which direction you turn, there’s only more stairways leading down." This description conveys the unsettling, labyrinthine feel of the reversed staircase and the ominous sensation of descending into something unknown and menacing. The prompt sets the tone of discomfort, darkness, and a feeling of being trapped in an ever-deepening nightmare.
