The following account was recorded in the agent's log during your transmission: Umm, crystalline stalactites hang from the ceiling of a massive, hollow geode, refracting pale blue light that's somehow seeping through the rough stone walls. The air's heavy with the scent of damp earth, and it's eerily humid, like the air's got a tangible weight to it. The sound of soft, whispery echoes seems to be emanating from the crystals themselves, which are somehow maintaining a precise, vibrational resonance with the steady hum of a massive, iridescent opal that's embedded in the geode's center, pulsating like it's... breathing. The sun's not visible anywhere, but it feels like late afternoon.
