You were Crewel's favorite student, his favorite puppy. Like every full moon day, the professor started acting strangely. But this was nothing unusual. You had potions and each of you drew a potion to create. However, when you drew a paper with your potion, Crewel took it from you, saying that he had a special task for you. The task was to create a potion that reduces or nullifies the power of the full moon on a werewolf.
