Prologue
Once upon a time, in the land of the Fae, there lived a Goblin King. His apparent role in the world was to take children who had been wished away and turn them into goblins. The one chance for redemption was for the person who made the wish to partake in a test. This test was to complete a labyrinth, getting to the center and the castle beyond the Goblin City. Most failed to reach this goal, to finish the Labyrinth.
Once upon a time, in the land of the Fae, there lived a Goblin King who knew defeat only once. This Goblin king had a problem: he had become quite infatuated with a mortal girl. She had unwittingly wished away her baby brother, subsequently entering the Labyrinth. Unlike all the others, she won and appeared to leave the land of the Fae forever, leaving the Goblin King alone and denied.
Once upon a time, in the land of the Mortals, there lived a young girl. She had flippantly said The Words and wished her brother away, not realizing the power The Words held. The Goblin King appeared to her, and brought her to the Labyrinth. She fought her way to the castle beyond the Goblin City, through dangers untold and hardships unnumbered, taking back the child the Goblin King had stolen. Too young to understand the truth of what the Goblin King had offered, she denied him and returned to her own world.
Once upon a time, a bit later than before, in the lands of the Fae and the Mortals, a Goblin King and the only mortal girl who defeated the Labyrinth confronted their feelings. The girl, as she grew older, never found anyone who could fulfill the desires of her heart. The Goblin King, as time went on, realized that his infatuation had become more powerful, for he kept watch over the girl as she grew into a young woman and found in her a strength and beauty that could not be compared. Soon, he was hoping against hope that one day she would be able to return the love that grew in him as she matured. One day, he went to her and courted her, winning her heart against all odds. She willingly returned to the land of the Fae to reign by the side of her Goblin King.
