A/N: the timeline of this story starts when Travis and Connor are 13 and 12, and it is during Harry Potter's first year. it's obviously before the second titan war, the timeline is a little wacky, so if you can just live with the hp series not being in the nineties, it would be awesome. (by my estimates it starts in the year 2000)

When the owl flew into cabin 11 at camp half-blood, no one knew what to do. The only thing the head of the cabin, Jamie Merck, thought to do was to go get Madison, leader of the Athena cabin.

Before he had a chance to go get her, the owl decided to go and sit on the shoulder of a young girl.

The young girl it had decided to perch on had curly, raven black, hair, a small amount of freckles across her tanned noise, and, oddly enough, purple eyes. She looked small and fragile at first glance, but in reality this eleven year old could take down a man three times her size, even without her special abilities.

The daughter of Hecate, whose name was Crystal Havenough, barely let any shock into her eyes. She had to maintain a cool composure if she were to avoid being picked on by her cousins and siblings.

By thoroughly examining the bird, she noticed that on the leg of the tawny owl was a letter tied there by a ribbon. She quickly pulled at the ribbon and took a hold of the letter. After she patted the owl on the head, it took off through the window that it came in. She saw it perch itself on a nearby tree so that she could respond to whomever sent her the letter.

Though on the outside she looked as cool as a cucumber, on the inside she was completely freaked out. Her grandfather had told her of this type delivery system, and she had no idea why she would be getting this mail. Her grandfather used to get letters like this all the time, but she had not seen a letter delivered like this since her grandfather (whom she considered to be her father because her actual father had died only a month after she was born) had passed away two years before.

Her grandfather told her about the existence of wizards when she was really young. Even in her early memories she could remember him waking around the kitchen waving his wand while pots and pans washed themselves. Her first signs of magic happened when she was about seven months old. She had just learned how to crawl, without her babysitter's knowledge, and she had decided to take a journey across the room. While her overweight babysitter was distracted, Crystal managed to get stepped on by the overweight lady. Because of the pain, she sent the woman flying up to the ceiling. When Crystal's grandfather got back to find a crying baby girl and a blimp lady he rejoiced at his little granddaughter showing her magic, but he had to use a memory wiping charm on the poor lady.

Crystal had no memory of this event, but she had heard of it from her grandfather. After remembering this tale, she thought of the wizarding school that he grandfather had gone to, Hogwarts.

'Maybe that's where this came from,' she thought to herself.

When she looked down at the paper she saw a whole bunch of green squiggles. Feeling the awkward stares from her cabin-mates she made no attempt at deciphering the dizzying words. Instead, she ran to Chiron, the camp's leader.

When she arrived at the doors of the Big House she knocked on the door. She heard Mr. D let out a grunt before he told her to come in.

Across the room she saw Chiron sitting in his magical wheelchair with a set of pinolche cars in his hands.

"Oh, it's Christy Haynes," said Mr. D after turning to the girl standing by him. He quickly got up and left because she had so rudely interrupted an ongoing game.

"Chiron, I have something I need you to look at," she said, ignoring the purposeful butchering of her name.

"What is it?" Chiron responded.

"It's a letter, I was wondering if you could read it, because it's in English and it's also cursive."

"Of course." Chiron grabbed the letter in Crystal's outstretched hand and looked to see if it had the address of the person who had sent it, but was greeted with a very specific address.

Ms. C. Havenough

Cabin 11

Camp Half-Blood

Long Island

New York

This immediately set him off. Only the gods and campers knew her address, but if they had sent the letter it would be written in ancient Greek.

What startled him into almost dropping the envelope was the wax seal. It bore the crest of the wizarding school, Hogwarts.

"I have a few important questions for you," Chiron said with as calm a voice he could muster. Crystal nodded her head in confusion. "Good, the first one is, do you know of a school called Hogwarts?"

"Yeah, my grandfather went there. Why do you ask? Is the letter from them? It is from them!" Crystal let out a small squeal of joy.

Chiron was slightly relieved that he did not need to explain the concept of witches and wizards to her.

"Yes it is from them. The second question I have is, are any of your other relatives are witches or wizards?"

"Yup, my great-grandfather was a pure-blooded wizard, and my grandfather told me that my father was a squib. And I guess I'm a witch, apparently. I never knew if I got my powers from Hecate alone, or if I was a witch too."

"Well, your knowledge of the wizarding world helps a little. The problem now is that you are against an oath that the gods made the day after Connor Stoll was born. An oath that prevents the birth of the offspring of God and semi-magical or magical beings. I do believe that that is the shortest lived oath in quite some time."

Crystal's face fell a little when she interpreted the words he was saying. Her existence is against the law of the gods. She shook it off when she thought about his words harder.

"Um, sir, what does Connor Stoll have to do with the oath?" Crystal cocked her head slightly to the right.

"This actually had to do with Travis Stoll. Like you, they both have magic." She let her jaw drop in amazement. 'How did I not know this?' she thought to herself. "Though children with both the powers of a demigod and witch or wizard are rare, they are seen as a threat. People like you three have large amounts of power that can destroy almost anything in your path. Connor Stoll was the last born before the oath because the day he was born, his brother happened to be quite upset. Travis caused all of the hospital's power to go off. Unfortunately it caused some casualties and even fatalities for those on life support. In light of the event the gods made the oath to prevent anything like that from happening again." Chiron had taken on a more serious manner at the mention of death.

"Oh," Crystal said, before pausing. Eventually the tension in the air for to be too much, so she decided to change the subject back to the letter. "So, what does it say on the papers?"

"Right, right, back on subject. It says, 'Headmaster: Albus Dumbledore (Order of Merlin, first class, Grand Sorc., Chf. Warlock, Supreme Mugwump, International Confed. of Wizards)

Dear Ms. Havenough,

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 own by no later than July 31.

Yours sincerely,

Minerva McGonagall,

Deputy Headmistress.'"

"Well this is awesome!" Crystal did a little happy dance before calming down again.

"When you go to Diagon Alley, that is the wizarding village, Travis and Connor will accompany you. They know the ways of the wizarding world, so you will not be confused by the shops, currency, and other people's actions." Chiron started thinking. He decided to pull some strings to get the Stoll brothers to transfer them into Hogwarts. Leaving Crystal on her own without any other demigods at Hogwarts was not an option. He'd have to contact Dumbledore soon.

"You're the best, Chiron!" Crystal was tempted to hug him, but decided it would be too weird and awkward. She turned around and started skipping to the doors.

"Oh, and Crystal" Chiron said as she started opening the door.

"Yes?"

"Do not tell anyone of this besides Travis and Connor. The gods and witches and wizards are meant to be kept separate."

"Of course, yeah, totally! Totes my goats!" Crystal excitedly opened the door and sprinted out of the house.

When she entered cabin 11 she immediately sat down to respond. She decided to keep it short and simple because her brain wouldn't allow her to write much. The stares of her cabin mates bore into her.

"Crystal, what was with the owl and letter thing?" asked one of the older campers.

"That? That was just this thing me and my old friend used to do," Crystal said, spinning a lie like she had learned from some of the children of Hermes. "We trained this owl to find us wherever we went if we wanted to contact each other. She just wanted to catch up on what's going on in my life." Her lie was fairly convincing. Luckily, the only people who caught her untruthfullness were Travis ad Connor. They only knew it was false because they too used this mail system, and nothing could be as coincidental as that.

As soon as Crystal had finished the letter she went off to find the owl. Five steps from the door the bird flew down and perched on her shoulder. She tied the letter to its leg using the same ribbon from earlier and it flew off.

As she started walking towards the arena to start sword practice she felt an arm drape around her shoulder and an elbow rested on top of her head.

"Hello Travis," she looked at the taller one, "and Connor," she directed at Travis' almost identical not-twin brother.

"So what was that letter really about?" Travis said.

"Well you already know, don't you?" Crystal raised her eyebrows. "Mr. and Mr. Wizard," she said in a hushed tone. Travis and Connor were almost shocked, but they knew that if she got that letter by owl, then she must know abut the wizarding world. The only thing that confused them was how she knew about their wizard-ness. "Chiron told me about you two. I always wondered where you went to school, and now I know that you go to a wizarding school."

"What school are you going to?" Connor asked.

"Hogwarts, my family mostly went there. My great grandmother went to Beauxbaton Academy."

"That's too ba-" Travis was cut off by Chiron coming up behind us in his horse form. Crystal already knew he was there, but the Stolls jumped three feet into the air and screamed like little girls when he clamped a hand on their shoulders.

"I need to speak to you two." The Stolls nodded their heads, still shaking a little from their near-heart-attack experience.

Crystal continued on towards the sword fighting arena and found an empty space with a sparring dummy. She hacked at it for about ten minutes until she was interrupted by the Stoll brothers jumping on her.

"SERIOUSLY?! You could have gotten stabbed! There is no reason great enough to dog pile a girl and risk getting cut open!"

"Yes-" Travis started.

"There is!" Connor finished. Sometimes these two acted so much like twins that even the campers thought they were at some times.

"What is it- and before you reply, GET OFF OF ME!" The two sprung up while avoiding Crystal's 3 foot long, celestial bronze, sword. She pressed a button on the end and it collapsed back into a wand. Her mother had given it to her on her eleventh birthday. When she wasn't using it as a sword, she used it to concentrate her powers and to control them. Surprisingly it still worked as a wand when it was in sword form.

"We have pretty awesome news!" Travis yelled.

"Agh, I'm two feet away, not two miles!"

"We're going to Hogwarts with you!" Connor shouted, ignoring Crystal's previous statement.

"That's great, but I thought you were already going there."

"Nope, we were going to one in Maine."

"It's the nearest one, but I guess since your family went to Hogwarts, you get to go too."

"But now we get to go with you!"

"You won't be alone in your demigodness there!"

"Okay, awesome!" Crystal hugged them both tightly around their waists. A small blush crept onto Connor's cheeks. Travis looked at him knowingly, but Connor stopped him by not-so-discretely kicking his shin.

Four weeks passed, and soon the trio were heading to London. Chiron had told them about a tavern called the leaky cauldron being the entrance to the place called Diagon Alley. It took them a little while before they could find the place. Between the airport and the tavern the Stolls had managed to pickpocket about twenty different people. In one pocket they found a gun and quickly discarded it in a nearby trash can or, as the British called it, a rubbish bin.

They went up to the bartender they asked him what door led to Diagon alley, and how exactly it worked. After some thought and the flashing of their wands for reassurance, he led them to the back door, which opened up to a small brick enclosure. The pattern he told them to tap was confusing, so the three split up the sequence to remember it.

When the brick wall folded back, all of their jaws dropped.

"This is better than the village in Maine," Travis muttered.

"It's almost as good as camp," Connor added.

"It might even be equivalent to camp," Crystal finished.

The whole street was filled with witches and wizards hurting to ask of the shops. They all had on robes and the older witches mostly had on pointy hats.

The shops displayed broomsticks, owls, nasty things in glass jars, books, and much more. At the end of the street was a marble building that curved oddly. The three assumed it was Gringotts, so they made their way towards it. Chiron had had someone make two accounts their for them.

When Crystal, Travis, and Connor got inside they immediately noticed the odd bank tellers. All of them were goblins.

They reminded Crystal of the Kallikantzaros that she had come across when she was on her way to camp. She was resting in a cave along the shore of Virginia when out of nowhere a group of five Kallikantzaros swarmed her. She managed to get out of the cavern with a broken wrist and several good sized scratches.

Crystal checked to see if the goblins had horse tails, and was relieved when they didn't.

The Stolls and Crystal made their way towards an open counter and tried to peer over the edge. The goblin leaves over the marble top and looked down at the children.

"Name and vault number," the goblin said, baring his point teeth at the kids in front of him.

"Crystal Havenough, vault 497." Her voice shook as she said this.

"Travis Stoll, vault 374." He said this with a little more confidence. His brother didn't say anything because they shared the same vault.

"And do you have your keys?" The goblin's voice sounded like a door hinge that needed to be oiled. Connor pulled the keys out if an envelope that he was holding and gingerly placed them on the counter top.

The Goblin picked them up and waddled down the steps from his pedestal. The three followed him as he made his way towards the back of the bank. The minecart they had gone into looked old and rickety. Travis looked nervously at his equally nervous brother and friend. After hopping into the cart it took off at a great speed. It seemed to be leading them straight to Hades. In both senses.

It stopped at vault 374 first. When the goblin opened the door it revealed piles of bronze knuts, silver sickles, and gold galleons.

"Travis, I do believe that dear Chiron added a small fortune to our minimal amount of money," Connor said in a fair British accent.

"Ah, yes, quite, my dear brother." They reached into the piles of money and filled their magically enlarged pouches with a fair amount of money. When they stepped back, there was hardly a dent in the pile.

After that they speed of towards Crystal's vault. She grabbed as much money as Connor had, before heading back to the cart.

When they got back to ground zero they let out a sigh of relief. Surprisingly Hades hadn't made the earth cave in around them, but in future times they planned to make someone else go down for them.

"Well," Crystal said when they reached the street, "now that we're out of that death trap, let's go shopping."
