Wizards, Mages, Warlocks, Witches, Sorcerers, Diviners, Channelers, they are called by many names often grouped together, the differences, and the classification there of is not something the average person thinks about. Those who will (or are forced to) think about such things have brought about what is the general consensus.
Those who can use magic of any sort are thought of as having the “spark”. Those with the spark are thought to manipulate the very fabric of the world on some level. It is generally thought that there are always consequences to using magic, though the repercussions are not always seen immediately. Therefore, in some areas of Ardanoth magic and magical research are forbidden. In select areas magic is highly regulated in others nullified completely. Ironically, with ancient magical artifacts.
