AN: Hi! This is my first fanfic, so please be gentle with me. This is set in the 7th HP book. I realize that the movie Labyrinth and HP books were published in different years, but for the story's sake, only 5 years have passed since her trip to the Labyrinth. Oh! And Hedwig's still alive (because she's cool). Since this is a crossover, there's definitely going to be some big deviations from the original HP storyline (if you didn't expect that, I'm sorry). As for pairings… I haven't quite decided. I'm definitely not going to do any crossover pairings (sorry if I disappointed you) but aside from that, we'll see what happens.

Disclaimer: I don't own Harry Potter or The Labyrinth; those belong to JK Rowling and Jim Henson respectively.

Harry was stuck. Not literally, though if he wasn't careful inside Shell Cottage he really would be stuck. Some of those hallways were remarkably narrow. No, Harry was stuck on what to do next. It wasn't as though Dumbledore had left him step by step instructions on how to defeat Voldemort (Step 1. Stay alive!); Dumbledore may have been great, but he was not straightforward. All those lessons on Tom Riddle's past to clue him in on how to find the Horcruxes could have been summed up in one sentence: He likes shiny things, so go find stuff with big brand names on them like Slytherin or Ravenclaw.

Sometimes, he wished he could just go to Voldemort right now and battle him till one of them keeled over. Dealing with the Ministry and enemies and even allies, sometimes, got exhausting. Everybody wanted to beat somebody else, but they also wanted other things. Take Griphook, for example. He was the whole reason Harry was sitting on the steps in the first place. Griphook wanted the Sword of Gryffindor in exchange for his help. Harry couldn't give it to him; he needed it to destroy the Horcruxes. They'd argued and tried to persuade him, but to no avail. Then Hermione asked if there was anything else he could even remotely want, and he said he wanted to go home to the Underground. The Underground? He didn't even know the goblins came from somewhere else! Apparently it was a kingdom of fae creatures with a Goblin King who had exiled Griphook by mistake; the King had meant to get rid of his cousin but got the name wrong.

Griphook told them to contact a girl named Sarah Williams. She would speak on his behalf. Why, Harry had no idea, but between giving up the Sword of Gryffindor or getting Sarah Williams to get Griphook out of exile, the answer was clear. Harry hoped this wasn't a trap of some sort for the Death Eaters to find them or just a prank Griphook was playing on them. But what choice did he have? The future of the wizarding world was depending on him.

He sighed and stood up. Sitting on the staircase with his head in his hands wasn't going to get him anywhere. Harry walked to around the house until he found Ron and Hermione talking quietly in the kitchen with some tea. They looked up at him expectantly. They already knew what he was going to say.

"Let's find Sarah Williams," he sighed. Hermione pulled out a letter, already sealed.

"I'll get Hedwig," offered Ron. Harry stared in surprise. Was he really that predictable?

Back in her apartment in Green Valley, California, Sarah Williams had just finished a report when she heard a scratching noise and looked up to find an owl at her window.

Oh no! her mind screamed. She covered her eyes and braced herself for broken glass. Her first impression was that he had come back for revenge after 5 years. She'd been waiting for this day ever since she left the Labyrinth. She just knew it wasn't over. A moment passed and nothing happened. There was no noise, not even the scratching. She peeked out from under her arms and saw the owl sitting on her windowsill staring at her calmly. She suddenly felt embarrassed at her theatrics. Upon closer inspection, Sarah realized this owl wasn't Jareth; it was waiting to be let in. In comparison, he would have no problem blasting the window open without so much as a word of warning.

Deciding it was safe, she reached out and lifted her window. The owl flew in and landed right in the middle of her newly printed paper. She glared at it and hoped it didn't leave any marks on the paper. Printing was expensive for a college student, after all. The owl stuck out a leg and looked at her expectantly. She looked down and saw a small note attached. Intrigued, she untied it and read:

"To Sarah Williams,

My name is Hermione Granger and I'm a friend of Harry Potter. I can't talk about the details in case this gets intercepted, but we need your help. Please send a reply with your address and we'll meet you there.

Hermione Granger"

Sarah blinked. She reread the note and blinked again. It sounded like some sort of prank except she'd never heard of these people before. It seemed like a lot of effort, maybe too much effort for a simple prank. After all, who trained owls to deliver letters? Speaking of… She glanced back at the owl still sitting on her desk. It was picking at her papers curiously now. She made a shooing gesture at it. It didn't help. She didn't know what to do now, except…

Crossing to the other side of her room, she stared into her dresser mirror and called, "Hoggle! I need you!"

After a few moments, Hoggle's face appeared in the mirror. He glanced around nervously. "Sarah? What's going on? I thought we were meeting tomorrow," he asked her. She waved the letter in her hand.

"I just got a letter from an owl, no less, from this girl asking me for help. Come out and take a look," she offered. Hoggle hopped out of the mirror. He took the letter from her hand and read it silently. Another moment passed in silence as Sarah watched Hoggle's eyes widen and mouth drop open.

"So," she began after five minutes passed and he still hadn't looked up, "is this a prank or what?" Hoggle lowered the letter but kept it in his hand. Then he went over to her bed sat, turning to face her. He didn't know how to begin explaining the magnitude of this letter. He had to tell her everything.

"Have a seat, Sarah." He motioned at a spot next to him. "This is gonna take a while."
