The following account was recorded in the agent's log during your transmission: Giant stalactites are covered in lush greenery and vines, suspended from the ceiling of a massive underground chamber. Like, the air's damp and cool, and I can smell the earthy scent of damp rock. A steady, gentle rain is falling from the stalactites, creating a misty veil that rises from the cave floor, and somehow, a perfectly intact, functional escalator is ascending from the depths of the chamber, carrying a batch of large, flat rocks upwards. Umm, the sound of dripping water is echoing everywhere, and the chamber's pretty quiet, except for the soft rumble of the escalator.
