The following account was recorded in the agent's log during your transmission: Umm, massive sheets of mirror-smooth ice cover a sprawling network of ancient, abandoned canals, with crystalline streetlamps that seem to be embedded in the frozen water, their facets reflecting a pale yellow light. The air's still and humid, with a strong scent of fresh citrus, and a warm sunlight filters down through the ice, casting no shadows anywhere. Above the frozen canals, the sun is somehow bisected by a perfectly flat, horizontal plane of darkness that seems to have an actual edge, like a physical boundary. The sound of gentle lapping water is coming from... somewhere beneath the ice.
