Reunion at the Old Castle Liko, Roy, and Friede arrive in Hammerlocke, where a Squawkabilly guides them to the ancient castle where Liko's grandmother, Diana, lives. Diana recognizes the pendant Pokémon as Terapagos, which she discovered in a dormant state as a child and gave to Liko for safekeeping after her former friend Hamber, a high-ranking member of the Explorers, approached her. She also reveals that Terapagos traveled with Lucius in search of the legendary paradise Lakua. As Diana leaves to retrieve Lucius' memoirs, Amethio's team attacks the group after tracking their location, but Terapagos confronts him.
