Dear diary comes to life

Long long ago, in a world of fairies, dragons, elfs and mythical creatures dwelled the 3 most powerful witches in the land of aulis.
These 3 witches Anna Aquafina and Amethyst sought the help of fairy to create something special, something magical. A diary. You might think oh crap how can a diary be magical. Why that's bullshit. But it is. Its no ordinary diary trust me.

The witches and the fairies after many months finally created their masterpiece. The diary. Butt there was a little problem. It was pink and the three witches hate pink. The fairies tried to reverse it but it didn't work. The witches tried and well same. So they tried to destroy the book and planned on doing it the next day. The fairies didn't want their work destroyed so they planned to ship the diary into a far far place which the humans call earth. There in the right hands it would be safe n they would tell the witches it was destroyed. So they searched for a baby with a pure heart n decided to ship it to her.
The diary would get to her when she's 15 and the fairies would monitor its travel and make sure it gets to its destination.

The next morning the fairies lied n told the witches it had been destroyed. The witches believed them and didn't try to find out if they were lied to and just took the words of the fairies. The diary has begun its long exhausting journey to earth.

About the diary.
Whatever you wish to happen as long as it is pure of heart it will come to pass. The diary can also become a human and keep another human company and gives u anything u want. Except changing time. It'll mess with the balance of things in the world.
