"Elien, we're in trouble," Jareth said.
"Has she made it that far?" I asked.
"Sarah has dreamed up more of the Labyrinth than any challenger before her. She's now more dangerous than Toby. I need to stop her somehow."
"What are you going to do?"
"Give her a ball. We're going to dance away as much of the night as I can manage. I need other dancers, including you and Koren."
I gasped. A dance. I loved to dance. "Do tell."
"It's to be a masked ball. Appear several years older than her. Wear masks. Most of the dancers will be illusions. Try to be near her as much as possible. Don't let her go bumping into people that aren't there."
"Got it," I said, turning and walking to my room, where I rapidly dressed and shapeshifted to appear adult.
Soon the summons came. Jareth threw a crystal at me, transporting me to his ballroom. I danced, masked, caught up in the joy of it. I watched Jareth dancing with the mortal woman, Sarah.
The clock struck twelve. Something was wrong. Sarah should have been enthralled by Jareth until midnight; instead, she broke free of him and ran to the ballrom wall. She picked up a chair and smashed it.
We fell out of the chamber. I don't know where everyone landed. I came down in a part of the Labyrinth I'd never seen-not too surprising, given that Sarah had made huge amounts of new Labyrinth while she'd been here. I shook my head, changed my clothes, and began to walk back to the castle.
I arrived there after Sarah, to find Jareth and Koren sitting in the throne room. "I lost," Jareth said, looking up at me. "She's back Aboveground."
"I could feel her connection to the Labyrinth," I said. "I could feel Toby's, too. What is it going to do to us?"
"Nothing, as long as Sarah wants it that way," said Jareth. "I've given her the power to call Hoggle and the others to Earth if she wants to, because I want them to remain her friends. She won't accidentally destroy the Labyrinth because she's mad at me if she's afraid for their welfare."
"Could she do that?"
"She could certainly destroy the parts she made, and most of the parts she changed. I don't know what that would do to the rest of it, and I don't want to find out." Jareth paused. "If someone with power got their hands on those two"
I shuddered. "Something is going to go after them," I said.
Jareth nodded. "And I can't protect them."
