From Akashic Records
When Esplandian's grandfather, Lisuarte, was imprisoned by the enchanter, Archalaus, Urganda took Esplandian from Firm Island in her magic boat, Green Serpent. He found himself on a rocky island, where, with a marvelous sword he found embedded in a temple wall, he killed a huge dragon.
A dumb sailor took him by sea to another country where Archalous lived in a castle on Forbidden Mountain. At the gate of the castle, Esplandian killed the giant Argantes and, inside he fought and killed not only Archalaus but is nephews Furion and Matroco. Their mother, Arcabone, threw herself to her death from the castle walls and Lisuarte was freed.
