Enter Domina. Go to the bar and talk to Elazul. Agree to take Pearl to Geo.
Enter Geo and go talk to Diana at Kristie's place. Tell Pearl everything is okay and talk to Kristie. Now you'll need to collect 3 keys and here's how:
- Go to Mephianse's office in the Academy of Magic
- Go to the City's gates
- Go to the Instrument Shop
- Go back to Kristie's Place to find Diana missing. Head to the Underground Battle Arena to find her.
Upon Completion: Return home, talk to Lil' Cactus, go downstairs (watch him write the Event on the leaf), and go back upstairs to save your game before continuing.
