"You must follow me," the girl explains, and her voice is
neither friendly nor unfriendly. "Destiny has decided."
Despite her words, you turn back and try to move away from her. Once
again, the invisible barrier is there, and your shoulders slump,
defeated. Turning back to the elf, you shrug with all the dignity you
have left. "Let's go."
You turn back and begin to quickly walk away, only to find you cannot
move. You throw yourself against the invisible barrier but to no
avail. The elf girl laughs, the sound like the tinkle of glass bells.
You turn back to face her, and, suddenly you can move.
