The Giants are on the March! The Rise of the Runelords Adventure Path continues! Driven to battle by a maniacal warlord, the once-peaceful stone giants of the Storval Plateau threaten to destroy the sleepy town of Sandpoint. Will fast action and quick wits be enough to save the defenseless community? Yet, even if the giants' initial raid can be repelled, only by striking at the heart of their titanic war machine—the black-towered fortress of Jorgenfist—can the menace be quelled. But who knows what mysterious bloodlust spurs the usually peaceful giants to war, or what mysteries lie beneath their ancient fortress?

A desperate refugee emerges from the earth's depths in shadow-cloaked Nidal with an urgent pleas. A new faction in the subterranean dark folk city of Lyrudrada -- a wicked cult called the Reborn -- seeks a fabled artifact called the Cradle of Night. Vanished demigods of the Shadow Plane once used this artifact to craft the elusive caligni race, and the Reborn want to use it to shroud the world in darkness once more. Cursed with the stain of shadow, the heroes must battle their way through the tomb of an ancient horselord chieftain before descending to Lyrudrada. Plots and schemes run rampant in this city riven with political upheavals and back-alley bloodshed, and the heroes must collect allies and information to confront the Reborn in their fortified fane. With the mysterious masters of the caligni race arrayed against them, can the heroes hope to shed their shadowy curse and claim the Cradle of Night?
