Meanwhile, Gareth Dragonsbane, a paladin of the Golden Cup and the King of Damara, led a company of six hundred men against a dragon flight that was threatening to rampage through the village of Ostrav. The Damarans defeated the frenzied wyrms, but during the fighting, Gareth’s soul was transported to the Plane of Shadow by a cabal of wizards working for Sammaster.
