In Terranigma, you play a young boy named Ark. He has grown up in his little village, isolated from the outer world by a stream of lava, and has never seen anything else beside it. One day, he and some other boys hear mysterious voices coming from beyond a door the village elder forbade them to open. Unable to resist their curiosity, the boys open the door, and Ark finds a box with a strange creature inside. By opening the box, Ark damages the balance between two co-existing worlds, and all the village people are turned into stones. Now Ark has to embark on a dangerous journey - to find five Towers, and to seek there the answers to his questions, and to liberate his people from a terrible curse.
