When murdered sinners fail to show up in hell, it's up to Salim Ghadafar, an atheist warrior forced to solve problems for the goddess of death, to track down the missing souls. In order to do so, Salim will need to descend into the anarchic city of Kaer Maga, following a trail that ranges from hell's iron cities to the gates of heaven itself. Along the way he'll be aided by a host of otherworldly creatures, a streetwise teenager, and two warriors of the mysterious Iridian Fold.

To an experienced thief like Krunzle the Quick, the merchant nation of Druma is full of treasures just waiting to be liberated. Yet when the fast-talking scoundrel gets caught stealing from one of the most powerful prophets of Kalistrade, the only option is to undertake a dangerous mission to recover the merchant lord's runaway daughter - and the magical artifact she took with her.

Kagur is a warrior of the Blacklions, fierce and fearless hunters in the savage Realm of the Mammoth Lords. When her clan is slaughtered by a frost giant she considered her adopted brother, honor demands that she, the last surviving Blacklion, track down her old ally and take the tribe's revenge. Yet this is no normal betrayal, for the murderous giant has followed the whispers of a dark god down into the depths of the earth, into a primeval cavern forgotten by time....

In the foreboding north, the demonic hordes of the magic-twisted hellscape known as the Worldwound encroach upon the southern kingdoms of Golarion. Their latest escalation embroils a preternaturally handsome and coolly charismatic swindler named Gad, who decides to assemble a team of thieves, cutthroats, and con men to take the fight into the demon lands and strike directly at the fiendish leader responsible for the latest raids - the demon Yath, the Shimmering Putrescence.

After a century of imprisonment, demons have broken free of the wardstones surrounding the Worldwound. As fiends flood south into civilized lands, Count Varian Jeggare and his hellspawn bodyguard, Radovan, must search through the ruins of a fallen nation for the blasphemous text that opened the gate to the Abyss in the first place - and which might hold the key to closing it. In order to succeed, however, the heroes will need to join forces with pious crusaders, barbaric local warriors, and even one of the legendary god callers.
