Merlin's Story

Merlin failed to protect Arthur, and Arthur did not forgive him for his magic. But now, 2000 years later, Merlin is protecting someone new-Harry Potter. In order to do so, Merlin joins the Malfoy household and goes through Hogwarts alongside Harry. Only Merlin's in Slytherin, and Harry hates him just as much as Draco. Don't know what ratings mean, pls tell me if it is wrong.
