A thousand years ago the world of Sarnaut was split by a cataclysm into countless islands drifting through the Astral space. Before long, people invented flying ships to travel from island to island, and found artifacts & treasures everywhere. Treasure hunters began to form squadrons, and equipped their airships with various weaponry to protect themselves in their hunt for riches. Bands of Cloud Pirates, as people called them, began to fight each other for the right to plunder the skies… Ready your airship, band together with your comrades in arms, and claim what is yours! For profit and glory!
