The following account was recorded in the agent's log during your transmission: A sleek, high-speed maglev train stretches across the middle of a gleaming, iridescent ice cave, uh, the train's surface etched with shifting patterns of circuitry that seem to pulse with energy. Crystalline shards refract sunlight into miniature rainbows along the cave walls as the air's filled with the smell of burning rubber and... it's really humid in here. A swirling mist gathers at the train's leading edge, somehow pulling the cave's glacial walls forward, incrementally lengthening the train itself like it's eating its own track.
