" The Old World was the domain of the Old School of wizardry—the “maintain secrecy and don’t attract attention” way of thinking. I guess they have a point, given the Inquisition and all. I don’t belong to the Old School. I have an ad in the Yellow Pages, under “Wizards.” Big shocker—I’m the only one there. I have to pay the bills somehow, don’t I? "
