To stop a devastating rampage of giants across the land, the party must venture into the lair of the stone giant thane Arnak to uncover the truth about why he has broken his peace with the neighboring dwarves. In the process, they will have the opportunity to retrieve important symbols of the fight against the giants and uncover a dangerous excavation. The adventure is part of the "Against the Giants" series originally by Gary Gygax, hence the writing credit.
