The following account was recorded in the agent's log during your transmission: Uh, Echo, I've got crystalline caverns unfolding above and below, like, vast and interconnected, lit by a faint, diffuse luminescence that seems to emanate from the crystals themselves. The air is crisp, with a hint of mineral freshness, and I can feel the faint, low-pressure charge of an impending storm – despite there being no visible weather outside, and no exits. Echo, a glittering, frozen waterfall hangs suspended at the cavern's center, halted mid-flow like a liquid sculpture, defying gravity and fluid dynamics; droplets of ice remain paused inches from the ground. The silence is almost palpable.
