The following account was recorded in the agent's log during your transmission: Rough, pockmarked stone covers the interior of a colossal, naturally-formed geode. Uh, warm sunlight seeps through a series of small openings, illuminating this maze of crystalline formations that somehow all seem to reflect images of an identical, deserted cityscape - like, a mix of Brutalist and ancient Sumerian architecture. A low, pulsating hum, almost a vibration, emanates from the crystals as they slowly, imperceptibly change color, while the air inside remains stale, thick with a metallic scent reminiscent of wet copper. The geode appears to be located inside a massive, slowly rotating asteroid.
