Jhank leads Gemwin, Bors, and Grom down to the lowest level of Runedarth - The Halls of Hammers and Mead, where they examine a pillar of sealed portals and then proceed into the Hall of the Pool. There, after defeating the gargoyles who dwell there, Jhank experiments with the controls to a large fountain to try to shut off the corrupt water flowing out of the mountain. They are able to get clean water flowing, then go down to explore the access tunnels to the cisterns and find one with clean water and another with corrupt water. They also explore a little bit of the Halls of Hammered Stone level, finding a route from the pool room to an exterior entrance.
