A New Dark Lord

Summary: Will thought that the Dark had gone forever. But that was before he discovered a whole new magical world, with its own evil side to fight. The Dark is Rising/ Harry Potter crossover. Set after Silver on the Tree and Harry's fifth year.

Harry Potter sat on the last swing that his cousin Dudley's gang hadn't managed to break, thinking about the end of the summer holidays, when he would be returning to school. Now this school was no ordinary school, it was Hogwarts School or Witchcraft and Wizardry. Harry Potter was a wizard, and Hogwarts was his favorite place to be. There he would be seeing his best friends, Ron Weasley and Hermione Granger.

But this year he knew would be different. This year Sirius, his godfather, was gone. He had died fighting Bellatrix Lestrange last year in the Department of Mysteries. Harry had known Sirius since his third year, when he had escaped from Azkaban, the wizard prison. He had, however, been innocent; Peter Pettigrew had framed him and then disappeared. Harry had grown to thinking Sirius a mixture between father and brother. Now that he was gone, he didn't know how he could survive a year knowing him to be dead. And now it was only a month until September first, in fact, today was Harry's birthday.

Harry was jolted out of his thoughts by the sound of the rusty hinges of the gate in the playground. A boy he hadn't seen before of about his age with brown hair had just come in to the playground. He, too, seemed lost in thought.

"Hi," said the boy.

"Hi."

The boy walked over to the bottom of the slide, facing away from Harry, and sat down. Harry felt a little uncomfortable with someone else nearby. But the boy obviously wasn't one of Dudley's gang and besides, he didn't have anywhere else to go, so he stayed where he was, swinging slowly back and forth.

Will was thinking about the boy with the black hair and bright green eyes. There was something strange about him that you didn't often see in most people. Will just couldn't place it. Behind the cover of the large slide, he turned around to look at the kid. There was something on his forehead, a scar? He squinted at him and saw that it was indeed a scar, in the shape of a bolt of lightning. That was defiantly not normal.

Will used his powers as an Old One to get a small hint of what the boy was thinking. Slowly, everything went out of focus as he concentrated on the black-haired boy. Then came the real shock. He couldn't do it!

'But only Old Ones can prevent other people from seeing your thoughts! And this guy is not an Old One. I am the last one, and he looks the same age as me! How is that possible?'

Harry, who hadn't noticed a thing, checked his watch. He jumped up, realizing he had been sitting here for two hours. He had to send a letter to Ron, and he wanted it to get there by tomorrow morning. Also, his aunt and uncle would probably punish him if he was out after dark, not because they were worried, but because they thought that he might be doing something "abnormal". It was almost dark out now, so he had to hurry if he wanted to get back. Harry went to the gate, pulled it open, and started jogging back to No. 4, Privet Drive.

Will saw him jump up and decided to follow him. This kid was weird. He did not know what to think about him. He ran to the gate, climbed over (to avoid making a creaking sound), and started running after the strange boy.
