Planescape is a campaign setting for the Dungeons & Dragons fantasy role-playing game, originally designed by Zeb Cook. The Planescape setting was published from 1994 to 1998. As its name suggests, the setting crosses and comprises the numerous planes of existence, encompassing an entire cosmology called the Great Wheel, as originally developed in the Manual of the Planes by Jeff Grubb (1987). This includes many of the other Dungeons & Dragons worlds, linking them via inter-dimensional magical portals. The setting crossed Victorian era trappings with a pseudo-steampunk design and attitude.

Planescape won acclaim on its unique visual aspects, products of artist Tony DiTerlizzi, Robh Ruppel, and Dana Knutson, winning a 1994 Origins Award. Pyramid magazine reviewer Scott Haring said Planescape is “the finest game world ever produced for Advanced Dungeons & Dragons. Period.” Haring described the writing as “wonderful”, also saying that it “has got one of the most distinctive graphic looks I’ve seen in any game product” and that the “unusual drawings remind [him] a little of Dr. Seuss.”
