Magyk refers to the powers of wizards. These include the ability to sense things, and to cause others to forget things. Magyk appears to be a highly advanced form of technology. The seventh son of a seventh son is said to have extraordinary Magykal powers. Wizards at the Wizard Tower also wear blue Ordinary Wizard Robes, except for the ExtraOrdinary Wizard who wears purple robes instead. Wizards' Apprentices wear green robes.
