You’ve lived on this remote island for your whole life, and never even considered that there was an outside world, as no one ever talked about it. Any talk of it was immediately shut down.
You’re 15 now, and there are whispers of gods. Whispers that they’re mad and that’s why we got a bad crop this year. So they need a sacrifice. The thought is dismissed from your mind. After all, you’re the chiefs daughter. It won’t concern you, you’re too valuable.
Storms plague your island for a week. Then a month. Then 3 months. Until one day, a ship docks at your island, full of things from the outside world. No one else seems to have noticed yet, so you go closer to inspect it. A sailor hops out. He’s tall, with a smug look on his face. Clearly not from here…you trip and fall out of the bush you were hiding behind. His head snaps in your direction
“Hey! Island girl! Bring us to your chief. We’re conquering this island.”
