I had an idea of this a while ago:
There should be a world event, or even just a dedicated island to the sovereigns, this is how it would work in my eyes:
-the island is medium sized (slightly bigger than a skeleton fort)
-it's flat
-it has defense systems (almost like a castle with tents inside or buildings)
-sovereign npcs on the island
-unique and decorated
-1 Crew per server should be able to settle deals to purchase or rent the island from the sovereigns. They should either be able to pay gold or complete various tasks/quests to get control of the island first though (I side more when the quests option).
-The crew that has control can store loot on the island and increase the value of the island and they can also have their own vault for loot
-other ships on the server could attack the island to claim or conquer it for themselves
-if they win, they can claim it as their own island and continue to build up value, or they can sell the island for whatever value it is at while claiming treasure that was stored
-If a crew builds it up successfully, they are able to sell the land for money
let me know thoughts on this idea
