Immediately following Volume 1, Jareth names Toby his heir and then disappears. Mizumi, the Queen of Moraine, and her two daughters decide to stay with Toby in the Goblin Castle "to help him out". After a brief scuffle in the "History of Toby" museum, Toby embraces his destiny as the new leader of the goblins and begins training for the role. Mizumi volunteers to teach Toby magic, giving him a small vial of magical water from Moraine. During their lessons Mizumi reveals her past romantic history with Jareth and his subsequent building of the Labyrinth "to keep everyone, including out".
