The following account was recorded in the agent's log during your transmission: Umm... crystalline caverns, lit by iridescent gas bubbles, stretch far into darkness, like... their walls pulsing in rhythmic patterns that mirror the convolutions of a sheep's brain. Dark tendrils of what looks like tar seep through the crystal, forming little branching veins as the air shimmers with a low-vibration hum. My chest feels like it's on fire and I'm suffocating; everything's getting blurry and dark... air pressure's still crushing, making my eardrums throb in sync with the cavern's rhythmic pulse. Sunlight from somewhere above illuminates tiny fossils of trilobites stuck inside the crystal walls, which seem to be, like, actively changing color.
