Deal Broker

In the drifting Isles there is little that could be cosidered as a law. And that means that every Isle and ship has their own. So as long as you act in accordance to the local law you are safe from the locals. But there are times where an agreement has to be made between ships or Isles that meet on the waves. But the word of the mouth is fragile and will not hold. Thats where the Deal Brokers come in. Poeple who have been granted a great power by the seas. They can perform the ancient ritual know as the deal. 
 

The deal

Is an old ritual that binds people and parties togather. When a deal is formed then all the participants are marked with tattoo like symbol. These symbols carry with them actual weight that depends on the weight of the deal itself. You, as the Deal Broker, have been granted the power to perform this ritual. You can perform only one deal per day. And the most important part is that the deal has to always be fair.
