The following account was recorded in the agent's log during your transmission: Uh, water's dripping from the tips of these massive, crystalline formations, suspended from the ceiling of a vast, underground cave system. The air's crisp and dry, with this faint tang of minerals, and sunlight's filtering in from... somewhere, casting an ethereal glow on the walls. A low hum, like a bass note, is resonating through the cavern, and I can see ripples forming on the surface of this small, circular pool of water, like something's rising from the depths. A small, antique door is embedded in the side of a crystal, partially submerged in the pool.
