Hello Harry
You don't know who I am, but I know you. I'm a relative of yours and I found out you aren't being treated right by your aunt and uncle. I understand if you don't trust me, you probably think this is a joke from the Dursley's. It's not because we both know your aunt and uncle wouldn't waste their time on you and that pig of a cousin of yours couldn't spell to save his life.
As an added reason for you to believe me I'd like to let you know my opinion of your relatives. Your uncle is a cheap, ungrateful, horrible fat whale of a man and his very existence makes me want to puke. Your aunt is a horrible, jealous, loud woman who looks like a giraffe and the fact she's not treating you right leads me to believe that she is even less intelligent than she makes you feel. I'm not going to bother insulting your cousin because he probably won't understand half of what I'm saying.
Now listen to me Harry, you are a wizard, just like your dad and your mom was a witch. That's why your relatives hate you; they think that they can get rid of your magic. Little do they know that they've actually made it stronger because you have to keep using it to heal yourself, I want to teach you about magic along with my sons Godric and Salazar and my two daughter-in-laws Helga and Rowena. We'll teach you all about the wizarding world and as much as we can about magic. We can also tell you about your parents, I should let you know that despite what your relatives tell you, they were killed by a dark wizard named Voldermort. I should also let you know that once you reach the wizarding world, you may meet a man named Albus Dumbledore. Everyone thinks he's a great wizard, he is but what most people don't know is he has a dark side. Everyone thinks he's the nicest thing since sliced bread, but I need to warn you to be careful. He's the one who put you with the Dursley's, he's the one who put blocks on your magic so your weaker and he has plans for you. I'll tell you more if you accept, if you do just say the words 'heir to magic'. Don't worry if you do, time's different where we are and it'll just be like a second for you when you get back. Now ignore the next line, it's not for you.
If you four are watching then you won't be able to see what happens if he accepts.
Goodbye Harry, I hope to see you soon.
Merlin

Harry had never been more shocked in his life, he knew the Dursley's definitely didn't write this and nobody else knows that he lives in a cupboard, not even Dudley's friends. He spent about half an hour deciding if he was going to accept. He weighed up the pros and cons of it. If it wasn't real then nothing is going to happen, if it was real then a whole new possibility of things could happen for him. Maybe he'd no longer be a freak, maybe he'd finally have a friend or someone who cares for him.
"Heir to magic" Harry whispered. A flash of light later and Harry was gone. He appeared second later and instead of wearing his cousin's rags he was wearing clothes of his own. He had black combat boots and trousers, a black shirt that seemed to be made perfectly for him and a black hooded cloak just like the ones from Hogwarts but this one had no symbols or colors. He removed the hood and his clothes instantly converted back to his cousin's hand-me-downs. A confident smile and happy smile was etched on his face and he did his best not to laugh. He checked his occlumency barriers were up and opened the door with a wave of his hand.
He was glad he didn't have to rely on a wand, he didn't need one. Merlin advised getting one when he was eleven, and he would but until then, he was perfectly content on using wand-less magic. He leaned out of the door and remembered that his relatives were gone. Harry took the opportunity to apparate away, he decided to visit Diagon alley and check out the wizarding world. Before he got there he placed a few glamour charms on, he was now a blonde, scar less, blue eyed boy. Diagon Alley was exactly like Merlin described, tons of wizards and witches running around and no one place was the same. Harrys first stop was the goblin bank Gringotts, upon entering he noticed the goblins looking at him with disgust, the were probably expecting him to be a jerk or too poor to be of importance.
"Hello" Harry bowed to one of the Goblins at the tills "my name is Harry Potter sir and I'd like to talk to the Goblin in charge of the Potter vault, I was hoping you could call him or at least point me in his direction." Harry hid a smirk at the Goblins totally stunned look, it was obvious he hadn't been expecting Harry or the respect he brought with him".
"Very well" The Goblin managed to compose himself "let me lead you to somewhere you can talk to him".
