The King should be allowed to ( hang / expel) a player who gets to much hostility towards another nation.
This player should become a Pirate.
A Pirate does not have access to any nations port unless He/she has a letter of mercy from a ports owners King.
The history way to hire a buccaneer
Pirates should have a pirate's heaven.
One of the small isolated Islands. (maybe between Vaasburg and Thorakas)
This should be the only place a pirate could have a Hideout. ( Auto Matic move when becoming pirate)
(Trading routes not possible. Its not a port)
Since pirates would not be allowed to enter any port (without letter of mercy)
There only way of getting building materials and crew members should be from plunder.
It should be painful to be expelled from a nation.
Another way of feeling the gallows rope
