Dead Sea Corsair
What curse befell the Dead Sea, a stretch of water off the coast of the Caliphate, is unknown, but it has given rise to undead mariners commonly known as Dead Sea corsairs. Rotting, worm-eaten, and perpetually wet, the corsairs are a form of zombie, though far more intelligent and agile, and not affected by blows to the head.
They sail the waters of the Dead Sea in rotting hulks, tattered corsair flags fluttering proudly from the masts. They have no interest in plundering vessels that enter their domain of their precious cargoes—they take only the living, who they drag down into the warm waters. Once death claims their victims, they rise again, ready to serve their captain in eternal damnation.
A typical Dead Sea corsair ship is commanded by a captain, with a khamsin jinn mage as his second-in-command. Against smaller crews, corsairs typically invoke becalm on the enemy vessel, then close and board, overwhelming the mortals with strength of numbers and undead resilience. Against heavily protected ships, the corsairs favor stealth. Under cover of darkness, they anchor within a few miles of their target, and then slip into the water. Incapable of drowning, they swim beneath the surface, quietly clambering aboard the ship and killing any sentries.
