The following account was recorded in the agent's log during your transmission: Uh, Echo, sunlight's reflecting off the surface of what looks like a perfectly still, giant soap bubble that somehow just exists, covering the entire cave entrance of some mountain range. Like, the air's got this crisp, clean feel to it, with a hint of minty freshness, and I can smell the faint scent of cave rocks. The bubble's surface is etched with tiny, cryptic symbols that seem to be from the Book of Enoch, while the sun beats down on it from high overhead, without causing any heat distortion or popping the bubble – it just... exists.
