The following account was recorded in the agent's log during your transmission: Uh, Echo, the sky's a swirling vortex of turquoise and silver above a perfectly circular, crystalline cave mouth. The air's still and cool, like a spring morning, but I can smell ozone-free, arcing electricity emanating from inside the cave. The opening is seamless, a glassy transition from rocky exterior to glittering crystalline interior, and just inside, a glowing, iridescent stalactite's slowly descending into a glittering, sapphire-colored pool, where its tip sends concentric ripples outward across the water's surface... and a flawless, silver-tipped feather's somehow piercing the pool's center, not moving, despite the ripples.
