World of Calidar is intended as the first in a series of releases, each describing a new adventure for the Star Phoenix and providing an expansion to the campaign setting. This unusual format is inspired from the stories written for Dragon Magazine, Voyages of the Princess Ark, and of course vastly expanded here. These were very popular in the 80s and 90s and a major selling point for the magazine. Although written with role-playing games in mind, contents are non game-specific, therefore easily adaptable to most RPG systems. Guidelines are nonetheless provided in the book for use with the Pathfinder Roleplaying Game.

The first edition was funded by a Kickstarter campaign that raised $19,654 between December 2013 and January 2014.
