Harry Potter and . the Charmed Ones? Disclaimer: I don't own Harry Potter and any Charmed characters but any character you are unfamiliar with is mine, all mine.

Chapter 1 Letters and Excitement
Albus Dumbledore was pacing the floor in his office. What was bothering him was that he wasn't sure if he should let all of the Charmed Ones come at one time or not. Finally he decided that they were strong together and vulnerable apart. So he sat down and started writing three separate letters.

Roam here no more

Be banished from here evermore.
The Demon vanished in a puff of smoke. "Wonderful job Phoebe you have certainly inherited my ability to write spells. You all did well girls." Their beloved Grams smiled at them. " Now go look at the books Leo got you from Diagon Alley and practice, practice, practice."
They all ran up to Piper's room, which was the biggest of them all. They got the books from Piper's trunk; Phoebe got the very old and sought after since there was only 7 in existence, charms book The Most Ancient and Almost Forgotten Charms Of All Time, Piper got Potions: A Masters Guide, Prue took out Animagus Transformations to Turning A Pin to A Matchbox and everything In Between. Despite that they probably not going to Hogwarts their Grams wanted them to learn wand magic. They all loved magic especially little Phoebe who was only nine. They each had their strengths Phoebe's was spells, Piper's were Potions, and Prue's was taking leadership and making plans.
"Guys." Said Prue.
"Yeah Prue?" Piper and Phoebe said in unison. " Maybe we should make some Memory and Healing spells & potions just in case we all go to Hogwarts."
" Why?" Phoebe asked.
"Because Pheebs, if have to vanquish a demon in front of anyone we don't want any questions asked."
" Kay!" said Phoebe and Piper. Piper got to work on some healing potions of her own creation. Pheebs grabbed a pen and some paper. She thought hard then wrote two spells down and thrust them in Prue's lap.

They read Forget what you saw

Tell no one at all
You will remember no more
After I knock on the door.
" Very funny Pheebs," she smiled impishly. "But it will work."
Let memories of these events

Cease to even be past tense

Wipe the slate as clean as air
Let no collection haunt them, ne'er.
"Good Work kid." She turned to Piper " Are you done?"
"Nearly These two need to simmer for 5 minutes and then this one 13 minutes. Do you want me to brew a truth serum?"
"Maybe later. "
" Girls. Come Here." Yelled their Grams.
" In a minute Grams. We have to put the stuff away!" yelled Phoebe. When they were done Prue teleported them down there.
" Prudence what did I say about teleporting in the house!"
"Sorry Grams. What did you want?"
" Girls Albus has decided that all three of you will start at Hogwarts this year!"
" But Grams Piper's ten and I'm nine Were too young to start at Hogwarts!" protested Phoebe.
"You and Piper will be taking tests to see if what year you would best fit in."
" But what about warlocks and demons we could put students in danger. Plus you need the Book!"
Dear only the occasional Warlock or Demon will get through and I've practically memorized that book plus I'm going to copy it I will keep the original while you get the copy."
" Okay then I'm in.," said Prue and Phoebe. They both looked over to Piper.
"Oh fine. If I want to see Grams I'll just take the Origami Express over here."
" What's the Origami express dear?" asked Grams.
" Remember my ability to turn two dimensional and then fold up and appear at the place I want to? We call it the Origami Express." Explained Piper.
" Creative dear. Now we must be going to Diagon Alley to get your cloaks and things." She was about to call for Leo but Phoebe stopped her when she said.
" Grams I'll take And Prue can teleport while Piper does the Origami Express."
" Phoebe you don't have a mode of transportation."
" Yes I do Grams." She argued and grabbed her arm and blue and pink and yellow and purple sparks and she "sparkled" Piper shrugged and Prue gaped.
" I didn't know she had that power." Prue looked hurt.
" She didn't tell me either Oh well shall we?" said Piper.
Without another word Piper turned into a 2 dimensional object and folded up real small and disappeared then Prue disappeared as well.

Author's Note The next chapter is called Diagon Alley { I bet none of you can guess why it's called that} and they meet the terrible Trio. If your wondering why they have different powers I'll explain since they grew up with those powers they get new ones every so often. When their doing the testing you should know most of their powers.
They still have the powers like they do on TV I've just added more.
