Pathfinder Campaign Setting: Cheliax, The Infernal Empire

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.
