King's Quest IV: The Perils of Rosella is a graphic adventure game developed by Sierra On-Line for the MS-DOS, Amiga, Apple II, Apple IIGS, and Atari ST computers and released in 1988. The player takes on the role of Princess Rosella, daughter of King Graham of Daventry (King's Quest I and King's Quest II) and the twin sister of Gwydion/Alexander (King's Quest III), who must save her father and a good fairy and destroy an evil witch. Critically acclaimed, it was one of the first games for IBM PC compatibles to support a sound card.
