Background:
In this reality, there is no Boy Who Lived. There is no Voldemort. The light and the dark still struggle for power, but there is no outright war between the two.
Here, Harry, Ron, and Hermione are not an inseparable trio. Actually, all three of them are in different houses: Harry in Slytherin, Ron in Gryffindor, and Hermione in Ravenclaw. Harry and Hermione had bonded on the train, and that bond could not be broken by their sorting. They grew to be the best of friends, studying and working together. The pair was very intelligent in their own rights, and together they soon became the top students of their year, if not the entire school.
Also, Harry had his parents all through his childhood. However, they were killed in a car crash the summer after Harry's second year. They were on a trip as a family when a truck ran them off the road and into a tree filled ditch. Harry was the only survivor. As per Lily and James' will, Sirius Black was appointed the boy's guardian. So, Harry James Potter became Harry James Black, when Sirius adopted him and made him the heir to the Black family besides the heir to the Potter family. Thus, Harry never met the Dursleys, the family Lily wished she did not have.
In Harry and Hermione's fourth year, the Tri-Wizard Tournament did happen. The champions were chosen: Cedric Diggory from Hogwarts, Fleur Delacour from Beauxbatons, and Viktor Krum from Durmstrang. Cedric won. Since there were no casualties, it was decided that the tournament would happen every three years, which meant Harry and Hermione would be eligible to compete. The next tournament would be held at Durmstrang. As soon as it was decided, the pair started learning Russian, the language they heard most of the Durmstrang students speaking.
That same year, Harry fully realized his sexuality. He was gay. He had inklings that he preferred boys to girls, but it really hit him at the Yule Ball. His date and friend, Pansy Parkinson, forced him under the mistletoe and kissed him for a few long minutes. The experience was horrifying, and those thoughts had obviously shown on his face. Pansy had smiled and patted his cheek. "You, my dear, are gay," she had said. Harry had to agree with her. She was one of the most attractive females at the school and had most of the other guys drooling after her. Since he felt nothing but horror at kissing her, he figured that his affections lay strongly with boys instead of girls. After that, Pansy and he became closer, and she joined Hermione as one of his best friends.
It took the rest of the year for Harry to come to terms with his sexuality. During his fifth year, he explored that sexuality. In that time, Harry also learned that he liked to wear women's clothing. Originally, it was a dare late at night in the Slytherin common room for Harry to put on a girl's uniform. From that moment on, Harry knew that he wanted to dress like a woman. So, before the start of his sixth year, Hermione and Pansy gave Harry a makeover.
They completely changed Harry's appearance. It was not all that hard because he had a rather feminine figure and facial structure. Since Harry's black hair had grown to be quite shaggy, they just needed to style it into a sleek bob. Pansy had wanted to add highlights, but Hermione said that would look tacky and distract from its raven wing quality. They taught him how to tastefully apply make-up. He found he was fond of silver, blue, and purple shades of eyeshadow. Harry got a girl's school uniform, as well as many skirts, dresses, blouses, sweaters, and jeans. He also got a few pairs of heels to make him taller than his normal five foot six. The finishing touch was his name. Harry changed his name from Harry James Black to Harriet Lily Black. Since he was still underage, he needed a parent's approval. Sirius readily agreed, wanting his adopted son to be happy.
On a different note, Draco Malfoy did not end up going to Hogwarts. Like his father wanted, the blond went to Durmstrang. He was the only Englishman in his year, but he did not have problems keeping up with the classes. His father had made sure his son was fluent in Russian, the language spoken at Durmstrang. Draco was the top of his year. He was strong. He was vicious. He was deadly accurate. No one could beat him in a duel, and his opponents tended to end up in the medical ward for extended periods of time. He had grown his hair into shaggy hairstyle, much to his father's disdain. He felt it added to his 'bad boy' image and kept it like that.
His best friend was Alexei Nikitin. He was the youngest son of a very dark Russian family with lots of power in the Russian Ministry. He was the same age as Draco. Both of them were of the similar builds: tall, broad chested, lithe muscles. However, that was where the similarities ended. Where Draco's skin was pale as ivory, Alexei's was a golden tan. Where Draco's hair was pale blond and short, Alexei's hair was a deep, blood red and fell to his waist. The man usually wore it in a bun. The two of them were the strongest and most terrifying pair at the school.
