The following account was recorded in the agent's log during your transmission: Dense, pulsating tendrils of a bioluminescent organism envelop the interior of a hollow, partially collapsed iceberg, casting an ethereal glow over the rough ice walls. The air's crisp and still, with a hint of salt, and I can feel a gentle, rhythmic vibration building up through the soles of my feet, like the organism's humming in sync with my heartbeat. Umm, outside, through a gaping hole in the ice, a frozen vortex stretches out across the polar landscape, somehow folding the sky and ground together into an impossible, Escher-like geometry. The sun's a distant, pale disk on the horizon.
