Court Wizard

Court Wizards, also called Court Mages, are the primary advisors of the Jarls of Skyrim and Counts of Cyrodiil on all things mystical and magical. Whenever a hold or city faces a threat from a magical source, such as necromancy, or vampires, the Jarl or Count consults his or her Court Wizard. In Skyrim, Court Wizards also serve as merchants of spell tomes for the Dragonborn. Each hold has its own Court Wizard, while all the major cities of Cyrodiil, excluding Skingrad, have Court Wizards.
