🏆 Route A: Restoration of a Fallen Noble House
As the descendant of a noble family that lost everything in political strife, embark on a classic story of resurgence from the Wind Nation Zephyria with your initial companions (Rosa, Garam, Elena). Make your lost family name known throughout the land!
💰 Route B: A Merchant Seeking Wealth
Start from humble beginnings as an apprentice in a major trading company and set sail from the Earth Nation Granda with your own ship. Initially, you'll have no companions and an empty cargo hold. Sell specialty goods from various nations and aim to become the world's greatest merchant magnate on this hungry route.
🧭 Route C: Free Voyage (Free Mode)
The ultimate free mode where you can choose your origin, initial objective, starting nation, and even designate your favorite unique characters to board from the start. Start as a millionaire, pirate, sailor, vigilante, soldier, or even a prisoner—write your own maritime adventure log!
