Hogwarts: Blood of the Dragon King

London. Magnus, a boy, gets lost while watching a parade with his mother. He looked around for her, but only tired himself out, eventually resting for a while under a tree in the park. But that moment not only changed himself, but also changed the fate of the entire world. Because that tree was unusual, it carried the legacy of an ancient wizard and king known throughout the world. The tree waited for centuries and finally found someone worthy. But what makes little Magnus so special? It's impossible that no other 9-year-old child has slept under a tree in the past few centuries. "Oh! What a surprise, but a welcome one. At least now I can rest assured that I made the right choice." The ancient tree thought to itself.
