Rise of the Brave Tangled Dragons at Hogwarts

This is basically a Crossover of Harry Potter, and The Big Four, Starring Merida, Hiccup, Rapunzel, and Jack. I will be using the Harry Potter world to show these four, and how they grow, as friends. Anything I write, I have seen in PG movies, so I'd rate it K. I'd appreciate it if you would take the time to comment, tell me what you liked or didn't like about it. I take criticism.
