I was fascinated with the concept of a Yandere Wizard inspired by a the tale of Merlin the Magician and Nimue who was, in some versions, The Lady of the Lake. In the legends Merlin was deeply in love with Nimue and accompanied her wherever she went and Nimue allowed in him in the hopes of learning Merlin's magic but under the promise that he never used his magic to enchant her, eventually Nimue made a deal with Merlin to give her love in exchange for being his apprentice until she eventually sealed him in a tree, the reason for why she did it varies by legends. But I was thinking that the Yandere Wizard could loosely be based off of that like they made you their apprentice in the hopes of gaining your life or something to that effect. It doesn't need to copy the legend exactly how it goes, and it can play out like how you want it too. Whether it's the listener sealing the wizard away, or the Wizard snapping, or somehow gaining a happy ending.
