Harry's Sorting
When Harry got his Hogwarts letter on his 11th birthday, he rushed over to the floo, said yes to going to Hogwarts and managing to pull all the teachers over to Potter Place for his party, not that they could refuse the puppy-eyes that Harry had perfected when he was 2, after realising every time he did them, Albus would give him sherbet lemons. Harry couldn't wait until the 1st September when he would be officially going to Hogwarts. What was even better was the fact that Arianna would be the schools administrator and Remus and Sirius would be the Defence Against the Dark Arts teachers.
1st September was bright and sunny, when Arianna, Remus and Sirius all took Harry to Kings Cross Station and Platform 9 ¾. Remus and Sirius would ride the Hogwarts Express with Harry to make sure that nothing happened. Arianna would floo to her brother's office and spend 7 hours annoying him, much to the amusement of the other teachers. If Albus needed to be taught a lesson, the teachers always called Arianna, and sit back and watch the last two Dumbledore's (their brother Aberforth had died in 1945, during Albus' famous duel with Gellert Grindlevald) chase each other around the castle.
Harry quickly loaded his trunk onto the train, with help from Sirius and Remus, kissed Arianna goodbye and claimed a carriage for all his friends. Sure enough, soon Neville and his great-grandmother, Augusta, who went to school with Arianna and sometimes helped her to annoy Albus, appeared on the platform. Harry waved at Neville who hugged and kissed Augusta, who promptly moved to stand and talk with Arianna, and leapt onto the train.
"Hi Harry" said Neville, "Hi Uncle Moony, Uncle Padfoot."
"Hi Neville," they chorused.
"Right, you settle in here and we'll go off and petrol the train and station, see you later" Remus said after the greetings.
10 minutes later the train had drawn away from the platform. Harry and Neville were soon joined by their other friends, Luna Lovegood (A/N: For the sake of this story, Luna was born August 1980. Also, Daphne Greengrass was born September 1979 and Astoria in August 1980.), Daphne and Astoria Greengrass, Tracy Davis, Terry Boot and Padma and Parvati Patil. The 9 friends sat and caught up on everything that had happened since Harry's birthday. Every half hour or so, Remus or Sirius would check that everyone was alright. Apart from an incident with Draco Malfoy and his bodyguards, Crabbe and Goyle (which was promptly dealt with as Sirius was in the carriage and threatened to remove Narcissa, Draco's mother, from the Black Family Tree, making the Malfoy's penniless), and Ron Weasley attempting to be Harry's best friend, a spot taken up by Neville and Luna, the journey was fine. Along the way, they also met a muggleborn student called Hermione Granger, who they invited in and became friends with.
When they reached Hogwarts, Professor McGonagall, who Harry greeted as Aunty Tabby, earning himself a glare, led them into the Great Hall. Everyone was staring with amazement at the ceiling, that mimicked the night's sky, but Harry didn't spare it a glance, having seen it many times before, instead, he waved to Albus (who was sitting on a gold throne in the middle of the dais where the teachers sat) and Arianna (who was sitting to Albus' left). McGonagall led them to a three legged stool, upon which sat the Sorting Hat.
After the Sorting Hat had sung its song, the Sorting began. The first of their group to be sorted was Terry who went to Ravenclaw. Tracy became a Slytherin as did Daphne and Astoria. Hermione was sorted into Gryffindor as did Neville. Luna and Padma joined Terry at the Ravenclaw table, while Parvati joined Hermione and Neville as a Gryffindor. When Harry was called, the Hall went quiet. It might have had something to do with the fact that Harry was called as Potter-Dumbledore, Harry. Harry had taken Arianna's surname of Potter-Dumbledore as a tribute to his favourite Uncle. The Sorting Hat, as soon as it touched Harry's head, screamed Gryffindor. Harry ran and sat down next to Neville, opposite Hermione. The only bad thing about the sorting was the fact that Ron also became a Gryffindor, which lead to him trying to sit next to Harry, only to have his way blocked by Dean Thomas, a muggleborns who was talking to Hermione about football.
Harry had done it, he was now a member of the Hogwarts community.
