The following account was recorded in the agent's log during your transmission: A massive, ornate astrolabe dominates the center of this abandoned, cyclopean observatory, like, it's easily a hundred times larger than any normal astrolabe and it's still somehow functional, ticking away with a soft, mechanical whir. The air's stale and musty, with a faint scent of old grease, and the only light comes from a narrow slit in the dome above, casting an intense, focused beam onto the astrolabe's face. Outside, the sky's a deep, foreboding indigo, with stars twinkling like ice chips scattered across the fabric of reality. Umm, the moon's currently stuck in a perpetual state of solar eclipse.
