The following account was recorded in the agent's log during your transmission: A sprawling network of iridescent, crystalline tunnels stretches out in every direction, umm, refracting pale morning sunlight filtering down through some unseen opening above. The air is heavy with the scent of damp earth and... something metallic, as a low-frequency hum vibrates through the tunnels, making my skin tingle. Water's flowing uphill through some of the tunnels, merging into a shimmering, crystalline pool that seems to be pulling the surrounding rock into its depths, like it's terraforming the area around it. Gravity's somehow warped, too, causing random sections of the tunnel walls to bulge outward into mid-air.
