If a PC plays the “Song of Elizabeth” found on the desk in the library on the harpsichord in this chamber, the conservatory fills with ghosts that dance about the room to the tune of the melody. The ghosts take no notice of the characters, save for two: Gustav and Elizabeth Durst, who stand beside the fireplace, staring at the PCs. When noticed, the harpsichord’s strings are cut, the ghosts vanish, and a grinding sound can be heard from above, signalling the opening of the secret passage in the attic.
If the PCs exit the room without playing the harpsichord, the sound of “Song of Elizabeth” can be heard faintly through the doors until the room is re-entered.
