The following account was recorded in the agent's log during your transmission: A colossal stone door with intricate hieroglyphics has swung open, revealing a vast, cavernous chamber beneath the earth's surface. Uh, the air's got this heavy, musty smell, and I can hear the sound of dripping water echoing off the walls. Echo, the space is lit by an ethereal, pulsating glow emanating from a series of iridescent, crystalline formations suspended within the rocky walls. In the center of the chamber, a massive, ancient astrolabe appears to be somehow... embedded within a fossilized, gargantuan tortoise shell, its gears and dials slowly rotating in tandem with the planet's celestial movements.
