Even before the British kids walked in, Annabeth wasn't having the best day.

First she'd had a stupid dream about adventuring with Luke and Thalia. Then Percy told her that an owl had landed on his head with a letter. "Well, what did the letter say?" she had asked impatiently.

"I haven't opened it yet." Percy said sheepishly. Annabeth sighed. Sometimes boyfriends were really annoying, even if you've been through Tartarus and back (literally). She took the letter from him and opened it. It said,

Dear Camp Half blood, "How do these people know who we are?" Percy interrupted. Annabeth shrugged and kept reading. As we're sure you know, we are coming to your camp or whatever it is, so we can meet! We apologize if the owl was a little bit pecky; she was the only one we had. We will see you later today,

Sincerely,

British wizards

Annabeth looked up and saw Percy mouthing the words "British Wizards". "What does that mean?" he asked. "I don't know." She said. "Maybe code words or something?"

"Maybe." Percy said, doubtful. "But that owl that Grover talked to, Grover said that the owl said that Wizards were coming."

"Huh." Annabeth said. "Maybe we should wait until they come, but don't tell everyone in the camp. If these 'wizards' are bad, we can take them."

"As long as they're not part of another quest." Percy muttered.

"You just jinxed us."

"Shut up."

So when Annabeth watched from behind a tree as the three teenagers took out things that looked like sticks and tried to force the barrier open by saying "magic words", she was confused. She looked at Piper next to her, whom she'd told about these apparent wizards.

"Are those… wands?" Annabeth whispered in astonishment.

"No idea." Piper whispered back. Her attention was jerked back to the kids when the one with the messy black hair said a word with his wand pointing at the boundaries.

Apparently they had even figured out there even was a boundary. These mortals are smarter than the rest. She heard a gasp next to her. Lou Ellen, the leader of the Hecate cabin, was the one who had let out the gasp.

"He tore a hole in the Mist!" she said, still whispering but obviously weirded out.

Everyone else started whispering too. "How the Hades did they do that?" "Oh no…"

"Shut up!" Annabeth hissed to them. The campers went immediately silent to watch the other kids. The messy haired boy was now appearing to hold open the boundary while the other two slipped in. Annabeth and Percy quickly stepped out of the trees, and started walking toward them.

Annabeth studied the newcomers. The first boy looked disturbingly like Percy with his green eyes and black hair. The girl had brown curly hair, and was looking worried and scared, but was trying to hold it back.

Annabeth knew that look. She saw it every time she looked in the mirror.

The other boy looked nervous also. He had vivid red hair, she noticed. The redhead opened his mouth to speak, but the girl elbowed him and he closed it.

"Um… hi." She said. "I'm Hermione Granger, this is Ron Weasley," she gestured to the redhead. "And this is Harry Potter." The boy looked around, like he was expecting someone to recognize the name, and looked relieved when nobody did. "And if you don't mind me asking," the girl named Hermione continued. "Who are you?"

Percy opened his mouth to reply, but Annabeth gave him a look. "Hello." She said. "My name is Annabeth Chase, and this is Percy Jackson. Come into the big house, and we'll tell you about ourselves, and I'm sure you will too." They followed Percy and Annabeth into the big house.

As soon as they walked in, the owl that had landed on Percy's head flew over to the boy named Harry. "That's your owl?" Percy asked. "She gave me a bit of trouble this morning. Also, why do you have an owl?"

"Sorry." Harry said. "Minerva gets excited sometimes. And of course we use owls. Don't you? Oh, I get it. They do things different in America."

"No they don't, Harry." Hermione said softly. Annabeth was still trying to process that these people used owls for communication. "Minerva?"

"Yeah." Ron said. "Why?" Hermione rolled her eyes. Annabeth felt a pang of sympathy for her, probably being the only voice of reason in their little trio. She could relate.

"Don't you know?" Percy asked. "Her mother is—"

Annabeth grabbed him by the elbow and steered him away. "You can't just give away our secrets to mortals, Seaweed Brain!"

"I wasn't about to!" Percy said, hurt. "Look, I just assumed that since they were here, they were demigods."

"What if they're monsters in disguise, Seaweed Brain?"

"That's the second time you've called me that." Percy pointed out. "If they don't know we're demigods, than the best thing to do would be telling them. That would be the best thing for peace. If we told them, they would tell us, wouldn't they?"

"I suppose that could work." Annabeth said doubtfully.

"And you have to be slightly friendlier." Percy said. "You're looking like a tiger that hasn't had a meal in a week."

Annabeth sighed, and then tried to soften her gaze.

When they walked back over to the others, Harry was fiddling with his stick, and Ron was tapping his foot impatiently.

"I apologize for my girlfriend. She doesn't like strangers."

That led to another argument, which led to finally Percy explaining what demigods were.

The 'wizards' had their mouths open, except for Hermione. She was looking at Annabeth intently, as if she was a human lie detector. She looked unaccustomed to hearing about a topic that she had absolutely no experience on.

Finally, Percy finished. "That was the weirdest, craziest, saddest story I have ever heard." Ron spoke up first.

"I suppose it's unsurprising that the Greek Gods are real. After all, magic works nearly the same way." Hermione mused. "I don't suppose that there are British demigods?"

"I'm sure there are." Annabeth replied. "We just haven't heard of them yet. Since the heart of Western Civilization is currently in America, there would be much fewer demigods here than there are there."

Harry frowned. "And I thought my world was weird."

"Dude, it's about to get a lot weirder." Percy said.

"Yeah." Annabeth agreed. "And we haven't even factored in Egyptian gods."

"What?" Harry, Ron, and Hermione all yelled.

"Tell you later." Annabeth said hastily, regretting saying anything. "Well, we extended our trust by telling you guys our stories. Please oblige us by telling us yours."

"Not it." Ron said immediately. Hermione looked at him sympathetically. Harry sighed. "I'll do it."

"Harry, are you sure?" Hermione said, alarmed. "That might not be—"

"It's just as much my story as it is yours." Harry looked at her. Hermione shrugged, as if to say, whatever you want.

"First," Harry began. "A demonstration." He pointed his stick at a lamp, which exploded. Percy jumped completely off his chair.

Then Harry pointed his wand at it again and it reared itself. "That is so cool!" Percy grinned.

"That's just the beginning." Ron said. "Just the beginning?" Annabeth repeated. "Just the beginning." Harry said.

"We are wizards. So, there are purebloods, half-bloods, and muggleborns."

"Half-bloods?"

"Not that kind of half-bloods." Harry said. "Anyway, a while ago there was this wizard called Voldemort. He went bad. Like, really bad. Worse than bad. He used to be called Tom Marvalo Riddle…"

A/N And then we go from there. It would take forever to describe the entire wizarding world, so I'll leave it up to you guys to decide how they do it. I'm begging all of you, REVIEW! I honestly don't care how you do it, just please do it. PLEASE PLEASE PLEASE! Thanks to all who did:

Kokonut518 (Thank you! I would love it if you kept leaving reviews)
me (Define in charge of everything. I wasn't exactly planning on doing that, but if you mean having them as the main characters then yes, they will be in this)
SoulfulKarma668 (Thanks! That means a lot)
me (I do not have an update schedule. Suffice it to say I will never wait a year before updating, and probably not a month. It could be between two days and two months)
