The following account was recorded in the agent's log during your transmission: A never-ending staircase spirals upwards into the darkness, like it was 3D-printed from some mad architect's fever dream. The air's thick with the smell of burned coffee, and it's humid enough that the stairs are slick with condensation, but somehow the whole structure seems to be made of bone-dry, dusty concrete. Umm, the stairs just keep going on forever, no railing or support columns in sight, and... a flock of starlings is flying down the center of the staircase, their formation a perfect Fibonacci spiral. It's around mid-afternoon, judging by the pale light trickling in from somewhere above.
