As the Hellfire Crisis dawns and spreads its turmoil throughout Avistan, the nation of Isger is being shaken up by the rebel organization the Hellbreakers League, which seeks to break Isger free of its oppressor and patron nation of infernal Cheliax. Player characters will carry out daring missions against Chelaxian strongholds, face off with the deadly Hellknights, and strike out against the forces of Hell itself! On the way, they'll run into dangerous enemies both new and old and uncover long-lost secrets powerful and ancient. Can the PCs stoke the fires of revolution and throw off the diabolic chains of Cheliax or will they be ground beneath the boot of oppression? Join the Hellbreakers and do your part! Hellbreakers is a 256-page hardcover Adventure Path designed for four characters, starting at 1st level and rising through the ranks to reach 10th level at the campaign's exciting conclusion. Hellbreakers also includes a gazetteer of the lands and people that make up the nation of Isger and a look into the cults of Urgathoa, as well as useful new items, exciting character options, and a host of dangerous monsters.
