Brigand Kings

Danger stalks the sea lanes! Brigand Kings are the most infamous dread pirates to sail the seas. Whispers of their deeds travel between every island on the ocean. Be vigilant! These Brigand Kings have put to sea with mayhem on their minds. No port or island will be safe until their threat is answered. The Navy calls for all brave sailors to pick up their arms and stand in the defense of their homeland.

Among their number:

• Azarbad the Great
• Admiral Finius
• Barnabas the Pale
• Gretchen Goldfang
• Vargas the Mad
• The Widow Queen

Brigand Kings are special brigands found at sea that can only be found by attacking red ringed vessels. At the start of the Sea Battle, if facing a Brigand King, a message is displayed proclaiming their appearance. Each Brigand King is unique with fierce fighters on their side that will not give up easily. If one manages to defeat a Brigand King, in addition to the normal booty, ye will receive a trinket as ransom for the Brigand King's safe retreat. In order to receive the trinket ye need to be a subscriber on Subscription Oceans or have a pirate badge or above on Doubloon Oceans.

As well as trinkets, if the vessel belongs to a flag that owns an island and a member of Royalty is on board at the time of the defeat they will be presented with an option to scuttle the Brigand King vessel. Scuttling a Brigand King vessel will invoke the wrath of the Brigand King and the scuttling flag's island will be the target of the next Brigand King Blockade. If they would rather not tempt fate there is also the option to let the Brigand King get away.

Brigand King Flotillas

Brigand Kings are always planning ways to seize control of an Island. Their main means of doing so is through their Flotillas.

Brigand King Blockades

While player Flags waged war on each other and struggle to dominate the Ocean, the Brigand Kings built up their fleets and prepared to seize control for themselves. They do so by their very own Brigand King Blockades.
