Witchcraft And Wizardry

Having graduated from the school of witchcraft and wizardry, you've suddenly been brought back. Only this time, you sense something sinister at work. The professor has gone mad. Mad with power. You've been sealed inside the room and within an hour he will extract all magic from you. Stripped of your wand and powers, you must use your wits to retrieve your wand and escape before you lose all magic forever.
