Danse Macabre: The Last Adagio Collector's Edition

Your sister's invited you to attend the biggest performance of her life: she'll debut as Donatella di Fiore, every ballerina’s dream role. She tells you to meet her after the dance but never shows up! What’s happened to your sister on this fateful night? Get into the theater and find a cast of ghosts all trying to tell you something. Some of them are better at playing music than talking, so this could take some digging on your part... Save your sister from a decades-old curse so this doesn't become her last encore.
