Dinotopia: The Sunstone Odyssey follows the story of Drake Gemini, his twin brother, Jacob, and their father, who have been stranded on Dinotopia for 10 years. At the beginning of the game, Drake and Jacob's father is attacked and killed by a rogue Tyrannosaurus while exploring the outer jungles of Dinotopia. After the killing, Drake and Jacob begin to go their separate ways, with Jacob joining a gang of dinosaur-hating humans called the Outsiders and Drake choosing to take on the role of a guardian of Dinotopia.
