There are a few things about running a campaign in Ptolus which you need to be aware of before starting.
After running a campaign in Monte Cook's Ptolus : City by the Spire for 3 years, I wanted to give you some advice on how to start your game in this huge, urban metropolis.
Monte Cook has launched a Kickstarter Campaign to re-release Ptolus in two new versions : 5th Edition D&D (5E), and his Cypher System. The book will follow the format of the original as closely as possible, and retain all of its premium design features. The Ptolus Kickstarter campaign launched in February 2020!
