Asking for their help to discover the source of the evil, the adventurers begin by searching the Vale of Shadows, an area containing Kuldahar's crypts, due to rumours of undead creature sightings. They encounter a cursed barbarian spirit named Kresselack (Tony Jay) who tells them that the threat lies elsewhere. Reporting this back to the druid, Arundel instructs the group to retrieve an ancient scrying item called the Heartstone Gem, so that he may discover the source of the evil more quickly. After finding the gem was stolen from its original resting place within a temple, the party travel to the caverns of Dragon's Eye, finding a number of the missing villagers being held there by lizard men. They eventually find the gem being used by a powerful Marilith named Yxunomei (Tara Strong). After killing Yxunomei and retrieving the gem, the party return to find Kuldahar under attack by Orogs, and Arundel mortally wounded by a shapeshifter disguised as the archdruid, who taunts them before vanishing. The true Arundel advises the party to take the Heartstone to Larrel (Michael Bell) at the fortress of the Severed Hand, the only one capable of using it now, before dying from his wounds.
