The following account was recorded in the agent's log during your transmission: Frayed, iridescent fibers cling to the surface of a crystalline cave, uh, its facets reflecting the pale blue glow of bioluminescent fungi that coats the rocky outcroppings. The air's thick with the sweet scent of honey and ozone, and the sound of gentle dripping water echoes off the crystal as the late morning sun casts an eerie, diffuse light through the cave's entrance. A steady, low hum, like a distant dynamo, seems to emanate from a perfectly spherical, kilometers-wide, containment field suspended within the cave's depths. Water vapor inside the field appears to be spontaneously condensing into gleaming, metallic cubes.
