Shannon Appelcline noted that when Ron Edwards was developing Sorcerer, "at the 2000 Gen Con Game Fair - while most of the industry was gawking over the release of the third edition of Dungeons & Dragons (2000) - Edwards' eye was caught by something else: Obsidian: The Age of Justice (1999), an attractive hardcover RPG independently published by the Apophis Consortium. Edwards decided that if they could publish an RPG while retaining ownership, he could do the same, and so he set to work on doing exactly that."[3]: 134 Dav Harnish, one of the authors of Obsidian, did one of the earliest reviews of Sorcerer on RPGnet.[3]: 140
