The (fictional) casino Lumière des Etoiles ("Starlight") is placed in Monte Carlo, Monaco. Under the casino lies a hidden storage facility. In A Grimm Warning, Conner, Bree and Granny Pearl travel there to retrieve the magic panpipe from Mother Goose's vault. The casino has green marble floors and golden pillars lining the walls. It is filled with elderly patrons. While Conner and Bree access the secret bank, Granny Pearl stays in the casino area.
