The Mages Guild is a guild dedicated to the collection, preservation, and distribution of magical knowledge with an emphasis on ensuring that all citizens of Tamriel benefit from this knowledge. Members of the Guild receive many benefits, including training, services, and education in the established laws regarding the proper use of magic. When Hannibal Traven took over the position of Arch-Mage in 3E 431 he immediately banned the practice of Necromancy from the Mages Guild, causing many members to leave the guild.
