For centuries, the empire of Cheliax stood as an example of the greatness humanity could achieve, with colonies and vassal states spread throughout the Inner Sea region. When the god Aroden died on the eve of his prophesied return to the mortal world, the empire fell into a vicious civil war. The victors of this conflict were the Thrice-Damned House of Thrune, who made pacts with the denizens of Hell to wrest control of Cheliax. In the decades since, many of the empire's holdings have fallen away, but at its core Cheliax remains a powerful nation, now both subservient to and allied with the legions of the Pit. Explore the vast nation and its inhabitants, from the gnomes of Brastlewark to the xenophobic, winged strix of Devil's Perch; from the rebellious citizens of Kintargo to Thrune loyalists in the heart of Egorian. A perfect supplement to the Hell's Rebels and Hell's Vengeance Adventure Paths, Pathfinder Campaign Setting: Cheliax, The Infernal Empire is a must-have!
