Also known as evil pirate gangs, these disreputable factions may be killed with impunity. No Reputation losses are incurred by players of any nation and each gang provides reputation boosts for various reputable factions. All but four of these gangs have associated bounty missions available from Pirate Hunter NPC's scattered throughout the Caribbean.
Major Pirate Gangs
These gangs serve important endgame functions by offering trade union Reputation, rare component drops, bounty titles, and reputation-boosting prisoners. The ships of these gangs mostly range from level thirty-five to fifty and all major gangs patrol primarily in the Antilles.
