The marauding orcs have been defeated, but great danger remains - the hill giant chieftain Grenseldek did not recover the treasures of the tomb beneath the besieged town of Trunau, and she will never rest until she has made them her own! The heroes must travel by riverboat through the orc-hold of Belkzen to the abandoned border fort that the giant has claimed as her lair and put a stop to the threat at its source! "The Hill Giant's Pledge" is a Pathfinder RPG adventure for 4th-level characters and continues the "Giantslayer" Adventure Path, a classic sword-and-sorcery campaign that pits the players against hordes of evil giants. Several new monsters, additional missions for the Mindspin Mountains region, an article on the ecology of drakes, and Michael Kortes's Pathfinder Journal round out this volume of the Pathfinder Adventure Path!
