The Grishaverse is a fictional shared universe of fantasy novels, short story collections, and a television adaptation created by Israeli–American author Leigh Bardugo. The universe consists of the nations of Ravka, Fjerda, Shu Han, Kerch, Novyi Zem, and the Wandering Isle, each of which adapts elements of language, culture, and tradition from countries of the real world (elements in turn drawn from different real time periods).[1][2][3] The magic system of the universe is the 'small science,' an art practiced by magic-users called Grisha with the ability to manipulate matter at its fundamental level.[4] As of 2021, there are nine novels in the Grishaverse: the Shadow and Bone trilogy, the Six of Crows duology, the King of Scars duology, and two short-story collections.[5]
