Eternal Eyes

Luke and his sister Elena are two orphans, living in a small house in the kingdom of Gross. One day, while exploring a local cave, the four youths find a mysterious jewel. Later, they travel to the city of Goondocks, where they find a similar jewel - along with a note left to them by Luke's and Elena's parents. They learn that their parents belonged to an ancient race named "Eternal Eyes" - people who could control inanimate dolls called Mappets. (mobygames)
