You have set foot inside a tall, stone tower. At the top of the tower you find a chamber with a floor made from rough-hewn timbers. Above, you can barely make out the rafters of the tower's conical roof against the dark gloom. Inside the chamber, there is a tall, gnarled wizard leaning over a writing desk, muttering to himself as he works on writing various spells. "I'm not finished yet," the wizard calls out over his shoulder, not unkindly. "Please come back later."
