King's Quest IV

King's Quest IV: The Perils of Rosella is a graphic adventure game developed and released by Sierra On-Line 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 defeat an evil witch. Critically acclaimed, it was one of the first PC games to support a sound card.
