YO, WASSUP? This is my first crossover, and its going to be like the same plot as HoO, but with Voldemort, Gaea, and Kronos rising , Percy (Jackson), Harry, Annabeth, Thalia, Ron, Ginny, Hazel, Fred, George ( what I think is funny is that Connor and Travis are like the PJO version of Fred and George), Frank, Hazel, Leo, Piper, and Jason set out on a quest to stop Camp Olympus( CJ and CHB) from going to war with Hogwarts, while at the same time trying to stop Gaea, Kronos, and Voldemort from rising. And what happens when Percy and Harry form a slight Rivalry? PS I need to really stop starting new stories, I have like 5 going at the same time right now,no, like 6 or 7.

Author Note: This first Chapter is how wizards met The Hunters of Artemis, eventually meeting Half-Bloods. No main Characters yet except for Thalia.

Thalia`s POV:

The Hunters of Artemis and I were on a quest to stop Mormo from destroying the UK(I don't remember where in the UK Hogwarts is, because I haven`t read the books in a long time, it's the PJO HoO books I read over and over), when we came upon a castle. I could sense the mist.

"This place is highly veiled by the mist" I said to my fellow Hunters.

" I wonder why" one said.

" Lets check it out" said Pheobe (Don`t know if I spelled that right, let me get out my PJO bookset….. nope, it`s spelled Phoebe) So we walked for the 10 ft. tall jawbridge door and knocked. A few seconds later an old lady that had an I-can-be-dangerous-when-I-need-to-be kind of look came and lowered the door. Her face was full of shock."MUGGLES!" she yelled, then She pulled out a –was that a wand? And yelled something fast that I couldn't quite understand.

" Did you just call me a MUGGLE!? What the heck is a MUGGLE!?" I yelled

" The memory spell.. it should have worked" the woman said. Now I was sure she was insane.

" well, you`re not muggles"

I pulled out my Bow and activated Aegis. She freaked OUT.

" NONONO NONO! It can`t be! Not right after You-Know-Who`s defeat!"

" You-Know-Who? No, I don`t know who! What are you talking about!?" I asked.

" She was Right" and she put her wand to her mouth and said: " We`ve got a got a problem….. H-B"
