From The Brothers Karamazov to Star Trek to Twin Peaks, this collection explores a variety of different imaginary worlds both historic and contemporary.Featuring contributions from an interdisciplinary and international group of scholars, each essay looks at a particular imaginary world in-depth, and world-building issues associated with that world. Together, the essays explore the relationship between the worlds and the media in which they appear as they examine imaginary worlds in literature, television, film, computer games, and theatre, with many existing across multiple media simultaneously. The book argues that the media incarnation of a world affects world structure and poses unique obstacles to the act of world-building. The worlds discussed include Nazar, Barsetshire, Skotopogonievsk, the Vorkosigan Universe, Grover’s Corners, Gormenghast, Collinsport, Daventry, Dune, the Death Gate Cycle universe, Twin Peaks, and the Star Trek galaxy.A follow-up to Mark J. P. Wolf ‘s field-defining book Building Imaginary Worlds, this collection will be of critical interest to students and scholars of popular culture, subcreation studies, transmedia studies, literature, and beyond.
