A wizard or witch is an individual capable of performing true magic, which is defined as the ability to manipulate matter, the laws of physics and chemistry and other constants of science, to a degree that is theoretically impossible. All witches and wizards rely on the use of Red Matter via channeling devices to act as an activation catalyst in order to tap into their powers; attempting to utilize magic without it is impossible.
Wizards only make up a small percentage of the Human population, approximately 0.1 percent of all humans worldwide as of 2029 have true magical abilities. The factors that determine the disposition to be able to manipulate Red Matter are unknown.The demographics for non-humans is also unknown.
The first known wizards were documented in texts dating back to the 11th century, though there is speculation by many historical scholars that there may have been wizards existing even before then.
