In January 2012, Cracked Monocle began a kickstarter to publish its steampunk roleplaying game, Tephra, which had been in playtesting for over four years. All they needed was a thousand dollars to cover some basic publishing costs and get their book set up at a print-on-demand company. Little did they know how far their kickstarter would take them. One month later, Tephra had raised almost $23,000. People from all over the world, from Brazil to Singapore to right back in Cracked Monocle’s home state of Texas, had pledged their support behind Tephra: the Steampunk RPG. One of the biggest draws was the custom, Kickstarter-exclusive Adversary Book full of crazy enemies, exotic adventures, and intriguing NPCs fit for any person’s Tephra game but pulled straight from the imagination of our Kickstarter backers. This is that book, and we thank you for making Tephra become a reality. From the backers who just wanted a copy to the backers who submitted their own adversary - all of your contributions were necessary for this dream to come true.
