Every captain wants the same prize: three seas, cleared and claimed. You take the helm of a lone sloop and sail out from Port on a campaign of expeditions, choosing your path through pirate waters, storms, and besieged harbors. Each sea is held by a named boss captain, and the crown changes hands only when their flagship goes down. Sink them all and the sea is yours. Come home richer, refit at Port, and sail out again against a harder tide. Or don't come home at all.
