Dread Trident examines the rise of imaginary worlds in tabletop role-playing games (TRPGs), such as Dungeons and Dragons. With the combination of analog and digital mechanisms, from traditional books to the internet, new ways of engaging the fantastic have become increasingly realized in recent years, and this book seeks an understanding of this phenomenon within the discourses of trans- and posthumanism, as well as within a gameist mode. The book explores a number of case studies of foundational TRPGs. Dungeons and Dragons provides an illustration of pulp-driven fantasy, particularly in the way it harmonizes its many campaign settings into a functional multiverse. It also acts as a supreme example of depth within its archive of official and unofficial published material, stretching back four decades. Warhammer 40k and the Worlds of Darkness present an interesting dialogue between Gothic and science-fantasy elements.
