Mickey brought the two girls back to the room they had appeared in. There wasn't a door, per se, but there was a large, ornate mirror mounted on one wall. It seemed like a normal mirror at first glance, but as they got closer, it stopped merely reflecting and became more like a dark window, mist swirling serenely behind the silvered glass. The faint outline of a keyhole appeared, shimmering slightly.

"This is the doorway," Mickey said, gesturing to the mirror. "We summoned you through it, once we were able to get it open. You should be able to use it to get back to your own world."
