The seas of battle-master are essentially controlled by pirates. Long ago there was an empire with a powerful naval force which controlled all the seas of the world. A rebellion within that empire drove the rightful king from his throne. The king fled to his loyal navy and took to the seas. With mastery of all the trade routes of the world the navy found it could sustain itself indefinitely. The pirate fleet continued to rule the seas while the empire, bereft of its greatest resource slowly crumbled into nothing.
Since then the fleet of the Pirate King has factionalized into competing and often waring trade companies, but they share a common pact, they'll never be holden to the rule of the land lovers. If any realm were to try and build their own fleet, the pirate nations would instantly unite against it. Therefore no realm bothers to try, after all the pirate fleets are more then happy to transport their goods and ferry their troops from place to place. Furthermore if any pirate fleet dared pillage a land realm, the other fleets would unite and destroy them. It is in this way that the pirate fleet and the realms of the land maintain their peace.
