The Pirate Guidelines: A Book for Those Who Desire to Keep to the Code and Live a Pirate's Life (Pirates of the Caribbean)
Made up of the great Pirate Lords, the Brethren Court is a governing council with the power to change or add to the Code. The original Pirate Code was set down at the second meeting of the Brethren Court, which included the pirates Morgan and Bartholomew, and serves as a set of "flexible" guidelines between pirates on the high seas.
