The following account was recorded in the agent's log during your transmission: Uh, a sprawling, crystal-encrusted cave system stretches out beneath a massive, iridescent geode, umm, refracting and reflecting the pale light of an unseen moon in shimmering patterns across the walls. Water trickles upward from the crystalline structures, feeding a network of glittering, ethereal rivulets that seem to be subtly shifting the air pressure around me. The air's heavy with the scent of damp stone and a hint of sugar, and I can hear the faint hum of an orrery - somehow the cave itself appears to be functioning as a working model of the celestial movements described in the Picatrix. It's around midnight, judging by the position of the moon.
