Explore Owzer’s Mansion in Jidoor and defeat the painting’s monster to recover 
Relm.
Walkthrough
In Jidoor, enter Owzer’s Mansion and examine the paintings. The rooms and doors change as you progress; inspect the portraits, take the available doors and follow the sequence to the painting boss. Heal before the confrontation and avoid assuming every visible door stays open.
After 
Chadarnook, talk with Relm to recover her and search the bookcase for Starlet. Take Relm to the base of the Fanatics’ Tower and speak with 
Strago among the followers; the party need not climb the tower to recruit him.
The tower itself is optional and restricts the commands normally available. If you choose to climb it, prepare spells, recovery and a plan for the summit boss’s final attack; save before committing to the ascent.
Checkpoint
In Owzer’s Mansion, investigate the book and the lights near the stairs to proceed. Examine the paintings as the route opens; some trigger battles. Chadarnook changes between forms, so watch the painting and heal while waiting for a safe opening. After the fight, search the bookcase for Starlet and bring Relm to the tower entrance.
