The following account was recorded in the agent's log during your transmission: Uh, a massive, slowly revolving door made of some kind of polished, dark stone is set into the side of a mountain, surrounded by a halo of water that's somehow not falling down the rock face. The air's crisp and thin, with a hint of wood smoke, and the sky above is a deep, cloudless blue, with the sun just starting to set, casting long shadows across the rugged terrain. As the door rotates, it's creating a low, pulsing hum, and a series of small, crystal-tipped stalactites on the surrounding rocks are somehow vibrating in time with the door's slow rotation.
