From their website:
Raider captains are some of the most notorious pirates to sail the black waves of Meredius. Each of them commands a crew of Satyxis and other inhuman monsters kept in line only by barbaric punishments and the promise of pillage and bloodshed. Guided by whim and murderous inclination, their vessels are the Scourge of the Broken Coast. Once the inertia of violence has taken a Raider Captain, she becomes caught up in the slaughter, leaping from victim to victim as the floor runs slick with blood and the air grows heavy with the screams of the dying.
