You find yourself stranded on an island in the South Pacific.
Life is scavenging for food, and you find hidden treasures along the way. You discover you're not alone. Crafting weapons and learning the art of making fire empowers you. Training your body gives you strength, and not too soon because there are run-ins with other inhabitants, including island gods!
Making friends has been beneficial. They teach you their ancestral ways. You might form a tribe with them and battle your enemies. For now you enjoy great pastimes such as fighting in The Pit, and you've become adept at criminal ventures.
One day, after you've conquered this island, you plan to gather supplies to build a boat and sail to the outer islands. You'll take them over too! Why stop at just one island?
