The third book in the sword of truth series

The Blood of the Fold continue to hunt down those with the gift, unwittingly being used by the Emperor Jagang, aka the Dream Walker, who tells some that he is the Creator and others that he is the Keeper. Either way, the images he shows them in their dreams, along with the commands he gives them, are enough to make them comply with whatever he says to do, including crimes that they normally would never commit. The only way to escape his control is to recite the oath that binds people to the protective magic of the Lord Rahl. After a pitched battle with the D'Haran army, the surviving members of the Blood of the Fold plead the oath, releasing them from the waking nightmare control of Jagang.
