The following account was recorded in the agent's log during your transmission: A spiral staircase made of iridescent seashells stretches down from a bright, blazing sunlight above, descending deep into an otherwise pitch-black cave, its air stale and heavy with salt. Uh, bioluminescent fungi is covering the rough stone walls, casting an eerie blue-green light on the staircase as it spirals out of view. Water's seeping from somewhere, creating a steady dripping echo that's somehow syncing up with the ticking sound of an unseen grandfather clock... embedded in the solid rock. The air pressure is building, and I can feel it making my ears pop.
