The boy wasn't living with his mother's sister, and he wasn't living under the stairs. No, the people he was living with took a page out of Cinderella. The small boy was living in the attic, one of the places in the stories that ring true is, he was like a servant, from the time he was tall enough to reach the stove, from a chair, he made every meal in the house. Not that he got to enjoy any of the food, he lived of two pieces of bread every two times a day, morning and dinner, and piece of fruit, if they had any for lunch.
His so-called aunt, tried to feed him less, but learned fast he would pass out before dinner was done. The horrible woman was no more his family the he was a muggle, or no-majs, as was the name he had learned for none magical humans. In the attic he found a little box filled with papers, and on one of these papers was information of adoption, for one Lillian J. Evens né Kowalski. Her mother had apparently given her away to a couple there had trouble, getting pregnant again. There was a note about the Kowalski family where on the run for something called the MACUSA. Apparently, Lillian's mother was a child of a no-majs and MACUSA employee, and the Americans frowned upon that apparently, and because of that Lillian and her mother where lacking papers.
Harry knew he had to get to some place called Diagon Ally and see someone called Ragnok. He was the head accountant, for his mother's vaults. First time he looked at the papers, a couple of days after he found them, he noticed the vault numbers, and numbers it where, there was 5 vault numbers in total. 913, 956, 965, 979 and 1000. He knew he didn't have to be there, but he still didn't know the way to Diagon Ally, so he had to say in this bad fairy tale.
The little nine years old, named Harry James Potter, made a deal with himself. He had till his tenth birthday, in a little under a month, to find a way to Diagon Ally, if he couldn't find a way himself, he would wait the year for someone to come, and he knew they would come, especially when he didn't get to Hogwarts for the first of September. Petunia really shouldn't make him stay with all her "forgotten" papers, if she wanted to keep a secret from him. But Harry still had questions, like why the headmaster for a school made it his job to place a child with a new family, and then didn't check on them.
Another question on Harry's mind was, why was he placed with people there weren't even his family. He would investigate that when he finally found the Ally. But first he had to make it through Dudley's birthday.
He had a full English breakfast to make, and then work on the roast for dinner. At least he cleaned the house totally the day before, so he only had to focus on the food.
He had a felling he would find the ally if he could just get to London, but he could get a train then it wouldn't be to far. He had the money, so why not try. The Dursleys were going on a weekend trip in a fortnight, and then he would look, in the meantime he would look through every box in the attic, to see if he could find more information about who he was. Now it was just the waiting game.
