The following account was recorded in the agent's log during your transmission: A gleaming, silver staircase spirals out of a vast, empty cave like a nautilus shell, vanishing into the darkness above. Umm, the air's crisp and still, with a faint scent of burning sulfur, and I can hear the sound of dripping water echoing off the walls. The walls themselves seem to be... breathing, slowly expanding and contracting like a lung, and a faint, pulsating light emanates from the staircase's railing, casting eerie shadows on the stone. The impossible geometry of the stairs appears to be defying gravity, looping back on itself like a Möbius strip.
