[You enter a void. In it hangs a single doorway, and a single unadorned full length mirror, facing each other a few paces apart. One of these, you came from, the other, you could go to. The ground is flat, a fine white sand. Otherwise... there's mist. Seemingly endless mist that makes it hard to see very far. But unlike the fog in the place you started, this seems charged with energy, taking on shapes and then letting them go again, as if trying to become something -- anything -- but unable to, quite, do so.]
