It seems to be a promising story, but the plot seems a bit thin. Slaughtering an entire village of people to get rid of Merlins, but leaving one alive? Not describing the villagers that well or the setting that much. Possible copyright infringement of World of Warcraft of the name Arthus, among other names. Not explaining how the magic system worked clearly made the story a great concept, but made it seem a bit scattered.
That's my two sense. If you want me elaborate on anything, just ask.
