Hell's Rebels was the seventeenth Pathfinder Adventure Path campaign, which began in August 2015 and ran through January 2016. It has as its setting a rebellion in Cheliax, starting with the formation of the Silver Ravens resistance group in Kintargo. The campaign's fourth chapter, A Song of Silver, is especially notable for being the 100th volume of the Pathfinder Adventure Path line. To commemorate the milestone, the book features an additional 32 pages of content, including a larger-than-normal adventure, an article on Aroden by Publisher Erik Mona, and a 32-page retrospective on the past 16 adventure paths, including a new NPC to be added to each.

"The city of Kintargo has a new lord-mayor, but he's not someone interested in maintaining that city's free spirit. Paracount Barzillai Thrune has placed the city under martial law, and his cruel proclamations and sinister plans for the city bode ill. Can a small group of heroes and would-be rebels stand against the might of the Thrice-Damned House of Thrune and the Church of Asmodeus and save their home town from being crushed under the boot of an infernal tyrant? Will one of Cheliax's most powerful inquisitors make the city his playground, or can the rebels known as the Silver Ravens rise up to bring a new era of freedom to the so called Silver City of Kintargo? Join the rebellion! Save Kintargo! DOWN WITH THRUNE!"
