You quickly shut the door and step back into the hall. That was a close one. Even now you can hear the whirring and buzzing of machinery in the room behind you doing Celestia-knows-what to the space that you had very nearly occupied.
"Sweet Celestia..." you breathe, realizing for a moment just how harried and ragged your breath is. You try to wrest is back under your control, going through the same breathing exercises the Wonderbolts recommend after a near collision. "What kind of pony even thinks up a room like that?"
Still, it's over now. Hopefully that room didn't have something important inside it, cause you have no interest whatsoever in going back into that deathtrap.
The hallway is much as you left it, a long bank of windows through which you can make out the glow of Ponyville beyond the crest of a hill, and a lot of stained wallpaper where pictures used to hang. There are four possible exits, TWO DOORS to your left, and the hallway leading both LEFT and RIGHT.
