The culture of Serpent Isles is deeply tied to Bilgewater, the island's nation. Bilgewater, over the years, has become an important stop for trade ships traveling near the Serpent Isles. While this increased the nation's wealth and influence on Valoran, the trade routes also brought piracy, and the island's inhabitants found themselves caught in a frenzy of pillaging. Things have relatively settled down since those days. Many inhabitants now strive to unite under Bilgewater in order to make themselves into a strong and independent society.
