One of the best (and worst) things about fantasy is that you're rarely done with a story after reading a single novel, watching just one movie, or even binging an entire season of television. Oh no, there are duologies, trilogies, spin-offs, and even 41-book franchises. Just look at Lord of the Rings, Wheel of Time, and The Witcher, to name a few — all have prequels, sequels, and more.
