Pirates hate and fear these hunters more then any Navy. These men were once pirates themselves and have turned their knowledge and skills to the task of hunting down their former Bretheran.
Pirate hunters come and go, some find it hard to resist the lure of plunder and instead of upholding the law ‘Go on the Account’ and become pirates themselves. (William Kidd comes to mind.)
At the moment there are two pirate hunters of particular note, Captain Benjamin Hornigold and Captain Miguel Henriquez.
