Chapter 1 : Aboard The Hogwarts Express

"You guys, were going to be late!" Blair Waldorf snapped in a brisk voice. She was so excited. Who knew she was a witch attending the best school in the wizarding world , well it wasn't just her who was special, Nate Archibald , Chuck Bass and Serena van der woodsen had all got letters too. Well of course there was also lonely boy Dan Humphrey and "Little J" aka. Jenna Humphrey attending which was not so great for Miss Waldorf. And then there was disgusting Vanessa Abrams Dan's ex Girlfriend.

Serena put a hand on Blair's shoulder "Hey B calm down were already on the platform".

Blair scoffed "Serena , I don't want to be left with no seats once we get on the express!" she was struggling with her luggage.

"Here let us help you with that?" Nate and Chuck offered.

Blair gave the two boys a sarcastic smile "That's thoughtful. But Dorota will handle it, DOROTA!".

"C-coming miss Blair!" Dorota (Official the Waldorf's housemaid) cried helping her with the luggage at once.

Chuck smirked "You brought Dorota? Oh my now that's cruel".

"I need her to help me track down my classes" Blair explained with a smile. "Besides since when do you care?".

"Since you started treating the lady like a servant" Chuck answered with a proud grin spreading on his face.

Blair scoffed "Where's Dan & Jenny?" she asked changing the subject "They were supposed to tag-along".

Nate chuckled "They must have got lost in the crowd, I'll go look for them".

Blair nodded slowly as she watched him leave, she turned to Chuck and stepped on his foot "This is going to be a fresh , new start. You hear me?".

Chuck laughed "Don't so sure, I know you still want me".

Blair scoffed "I'm uh going to find Dorota, don't follow me". With that she walked briskly away.

"Dan , Jenny! Where have you been? We were meant to stick together" Nate demanded as he finally found them.

Dan's eyes narrowed "Look Archibald do you think I've forgotten".

Nate sighed. Kissing Jenny Humphrey was the biggest mistake he'd ever made. Dan Humphrey hated him for it "Blair's looking for you" he said firmly.

Dan scoffed "Well tell her to wait, I'm looking for Vanessa".

"Vanessa?".

"Yeah she went missing and now we can't find her" Jenny explained frowning.

"Well the train leaves for Hogwarts in a few minutes, we won't have time-".

"Nate you bet we will" Dan interrupted with a snarl.

The three heard the train whistle it was time to leave. Dan sighed sadly "I swear if anything's happened to her-".

Nate took a deep breath "Look I know Vanessa, I know you may not want me saying this, but …... I think she bailed".

Dan tried to hide tears forming in his eyes "Yeah, yeah I guess your right".

Nate smiled warmly "Come on man, lets put the past behind us".

Dan nodded slowly, finally he and Jenny followed him back to the gang.

"Anything from the trolley!" Called the trolley lady, Harry Potter got up, before he could answer a beautiful girl (known as Cho Chang) asked for two "Pumpkin Pasties" He blushed and walked back to his compartment and chuckled to himself.

"Wow this is big, Death Eater's at the world cup" Hermione Granger gulped as she finally stopped reading the Daily Prophet. "Wasn't there any security?".

"Yeah loads" Ron replied.

Harry's scar hurt he winced, unlucky for him Hermione noticed this quickly "Your scar? It's hurting again is it?" she demanded.

Harry gave her a amused look "I'm fine".

Hermione frowned "You need to tell Sirius about this. About what you saw at the world cup , and the dream".

Harry knew she was right and so he began to write the letter …...

"EWE!". Blair screamed in horror the school uniform was horrible in her opinion.

Serena laughed "Come on B it's not so bad".

"Hogwarts school here we come!" Chuck exclaimed with a grin. "I think were gonna have a good time".

"Oh no not here Chuck" Nate sneered.

What do you think? Yeah I know I've got this hobby of starting fanfics and never finishing them, don't worry I will. Anyway have any suggestions please let me know, hopefully I'll get our favorite Upper East Siders to meet and greet Harry Potter and his friends very soon ! The next chapter will be about The Sorting Hat and the Triwizard Tournament announcement.
