Hard fantasy is a term used to describe different types of fantasy literature, especially those which present stories set in (and often centered on) a rational and knowable world. In this sense, the term is analogous to hard science fiction, from which it draws its name, in that both build their respective worlds in a rigorous and logical manner.[1][2] However, the term has other uses, and the scholar Misha Grifka-Wander has argued that it is both unpopular and inaccurate.[3]
