Prompt

In a desolate wasteland stands a seemingly endless tower, built of materials that change texture when touched: rock, wood, metal, and something that seems to beat like a heart. Upon entering, a spiral staircase leads you upwards, but each level is a different space: a desert, a flooded palace, a sky without a floor. On each level, a figure identical to the traveler watches you without moving, but when you look down, the staircase always seems higher.
