Chapter 1: It Started With a Letter…

Carolyn was walking around Station Square, like she did every day. She had shoulder length brown hair and green eyes. She was wearing a dark red t-shirt and black and white shorts, along with a pair of blue flip-flops.

She looked around, hoping to find one of her friends. She often hung out with Sonic and the gang. She had just appeared out of nowhere one day in Eggman's fortress. Some stupid invention brought her there, but her arrival helped in the destruction of the place.

"Man, I'm bored," she sighed. "There's nothing to do. Sonic's probably off doing some heroic mission, Tails is probably working on some new invention, Knuckles is probably on Angel Island, and where ever Sonic is, Amy'll be there." She sighed again and leaned against a building, staring at the cars passing by. Her thoughts began to drift when a sudden boom brought her back to reality.

"What just happened?" Carolyn asked herself, looking towards the area where the explosion came from. One thought popped into her mind: "Eggman!"

Looking towards the sky, she spotted one of his flying fortresses. She quickly began to run towards it. "Well, at least there's something to do now…" she said to herself. "But how the heck am I going to get up there!"

Her question was answered when she spotted Sonic, Tails, and Knuckles, who had quickly responded to Eggman's attack.

"Carolyn, right on time," Sonic said, noticing her. He glanced at the fortress, and then to Tails. "Can you fly us up there?" he asked. Tails nodded, and one by one, flew them up to the fortress.

"This place looks the same as last time!" Carolyn said, looking around the place. "Doesn't he ever change or redecorate, or anything?" There was a crackling noise, and a monitor in front of them sprang to life, showing the image of Eggman.

"Well, Sonic, you made it! So glad you could come," Eggman said a malicious tone to his voice. "I just wanted you all to 'test' my new invention for me."

"Like we would ever do that!" Tails said, glaring at Eggman. "What stupid invention did you create this time?"

"Why don't you see for yourselves?" Eggman cackled. A hole appeared in the floor, and the group fell down to the lowest level of the fortress. They landed with a thud in the same room as Eggman. Behind him was a strange looking machine, with lots of buttons and controls that only Tails could understand.

"What's that hunk of junk supposed to be?" Knuckles asked, eyeing the machine suspiciously. Whatever it was, if it was created by Eggman, it couldn't be for good reasons.

"This 'hunk of junk' will be your demise!" Eggman shouted. "This machine can and will…" He began to go on and on about his machine. Sonic, Knuckles, and Carolyn had no idea what he was talking about- scientific talk and all. When he was finally finished rambling, they all turned to Tails for the translation.

"It's a machine that makes a portal to another dimension," he told them. "It sounds impossible, though. I doubt it works." Eggman glared at them.

"Oh, it works!" he told them. "You can find out for yourselves, when I send you through the portal!" He laughed and pushed a button. A spinning vortex appeared, proving that it did indeed work.

"One problem with your master plan," Sonic told Eggman. "There's no way you can get us through!"

"Oh really?" Eggman asked Sonic. A malevolent look gleamed in his eyes, and he pushed another button. A couple of robots fell down from the ceiling, landing behind Sonic, Tails, Knuckles, and Carolyn. The robots grabbed them and held them tightly, beginning to push them towards the portal.

"We should've seen this coming…" Carolyn grumbled. She began to thrash about wildly. The robot tightened its grip, causing her to wince in pain.

"You won't get away with this!" Knuckles yelled at Eggman. "We won't let you get rid of us so easily!"

"Oh, I think I can and will," Eggman told Knuckles. The robots came to a stop in front of the portal. "If I push this button, the robots will throw you into the portal." His finger hovered over the button.

"And you're telling us this why?" Carolyn asked him dryly. Eggman glared at her, but then he smiled wickedly.

"Sarcasm will get you no where," he told her. He was about to push the button when five owls flew into him, coming from the portal. One of them flew out of the fortress. "What?" Startled, he accidentally pushed ANOTHER button (Lots of buttons, huh?), which made one of the robots release Sonic. Sonic quickly took this opportunity to destroy the robots and free his friends.

"Well, Eggman, looks like your plan has backfired again," Sonic taunted him. He glanced over at Carolyn, who was…PLAYING with the owls! "Are you playing with those birds?" Sonic asked her. "At a time like this?"

"It's a letter, to me," Carolyn told him. "It has my name on it…there are letters for you three, too!" Sonic gave her a curious look, but quickly turned back to Eggman.

"Well, I have no idea why those owls have a letter for us," Sonic said, "but we've got to focus on Eggman now!" But Carolyn was already opening the letter. She began to read it aloud.

"Dear Miss Carolyn,

We are pleased to inform you that you have been accepted at Hogwarts School of Witchcraft and Wizardry. Please find enclosed a list of all necessary books and equipment.

Term begins on September 1. We await your owl by no later then July 31.

Yours sincerely,

Minerva McGonagall

Deputy Headmistress.

P.S. Seeing as how you have had no experience with magic before, you will start out in the first year, regardless of your age." Carolyn reread the letter. "Magic?" she said, surprised. She grabbed the other letters and read them as well. "We've all been accepted into a magic school!" Sonic, Tails, and Knuckles stared at her in disbelief.

"But how?" Tails wondered. "We're in different dimensions…and magic!" He looked extremely puzzled.

"Well, I suppose if they're witches and wizards they could get to our, er, 'dimension'," Sonic said, grabbing his letter. Everyone was so focused on the letters; they didn't notice Eggman sneaking away until the last moment.

"Eggman's getting away!" Knuckles shouted, pointing at Eggman. He was sneaking towards the portal. They ran towards him, but Eggman jumped through the portal before they could catch him.

"Great, now what?" Carolyn asked. She eyed the portal warily.

"Should we go after him?" Tails asked. He looked at the portal. It was impossible to see where it led.

"Well, we can't just let Eggman reek havoc in another world," Sonic said. "Though it'd be nice to get him off our backs…" Carolyn gave him a dry look. "Besides, I'm sort of curious about this 'Hogwarts' place."

"I agree," Carolyn said. "I say we go through that portal! Besides, it couldn't hurt, right? All in favor raise your hand!" Everyone raised their hand. "Great, then let's go!" They all took a deep breath and jumped through the portal.


Note: I do NOT own Harry Potter OR Sonic...though I wish I did. The only character I own is Carolyn. She's just there because...well, I have no idea. Because I said so!
