Lost in the Labyrinth

In this au inspired by The Labyrinth (the movie with David Bowie from 1986), the reader is a babysitter who has made the mistake of wishing away the child they're sitting to the Goblin King. Now they must recover the child from the center of the maze or else both they and the baby will be trapped in the maze forever, property of the Goblin King.
