I have been reading The Wheel of Time books, and found the Seanchan Damanes to be very similar to The Tethered Mage books, where magic is rare and strictly controlled (even with minders that use devices to control the magic). I also saw a very similar control of magic in The Fifth Season where Guardians controlled the Orogenes' use of magic.
Is there a clear origin to this trope of strictly controlled magic (typically wielded by women) and a non-magic class that controls the wizards/witches?
