Brotherhood of the Coast

This group is said to have been formed by Pirates, who may have been members of the Knights Templar after they were dissolved by Pope Clement V. This is said to have been formed in the Caribbean. (See "The Templar Pirates" page 1)

The founders were probably Huguenot buccaneers in Tortuga. (See "The Templar Pirates" page 58)

This group had a rather good set of rules to follow.  See Brotherhood of the Coast Rules.
