I warn you! this is probably the worst work I have done; I decided to submit it aniway. This one came from an idea that I had since I was a child. "The stone in the rock" was one of my favourite Disney's movies and when I was watching the magic duel between Mim and Merlin and in the ending when Mim turn herself in the purple dragon I always thought: "Come on Merlin, turn yourself in a bigger dragon!" So here it is my work.
