A sudden assault on the town of Sandpoint by stone giants and a dragon brings the looming threat home. Ezren, Merisiel, Harsk and Valeros learn that attack was just a scouting party, that the stone giants are massing for war. The only way to disrupt their advance is to strike at the Jorgenfist, the fortress of Warlord Mokmurian, the sinister giant responsible for gathering his people for war.

Ezren, Merisiel, Harsk and Valeros answer a desperate call for aid from Hook Mountain. A tribe of ogres has slaughtered the garrison of a small keep, including the famous retired war hero stationed there. The few surviving rangers need the heroes to help them retake the key fortification. And in the surrounding wilderness, a sinister force is growing.

Sandpoint. An ordinary town on the Lost Coast of Varisia. When Ezren, Merisiel, Valeros and Harsk arrive, seeking rest from their adventures, it seems the town’s annual Swallowtail Festival will give them what they need - until goblins attack during a ceremony to consecrate the town’s rebuilt church. After defending Sandpoint, the adventurers discover a sinister plot to return an ancient evil to Varisia.

Ezren, Merisiel, Harsk and Valeros discover that Karzoug, an ancient wizard from the long-dead empire of Thassilon, has returned to life. From his city fortress of Xin-Shalast high in the mountains, he has been using the giants to harvest souls to reclaim his lost power. The secret to defeating him before he can reclaim his realm and enslave the region lies hidden in a deadly dungeon called Runeforge.

Having steeped their weapons in the ancient magic of Thassilon, Ezren, Merisiel, Harsk and Valeros prepare to confront the newly risen Runelord Karzoug at the seat of his power. To do so, they must travel high into the mountains, to the fabled city of Xin-Shalast, where they are confronted by enormous giants and dragons before they can finally confront the mad wizard of greed in his mountaintop palace. Yet can defeating Runelord Karzoug stop the rise of the Runelords? Or are there more terrors yet to come?
