You were part of the crew of a cursed captain. Nobody knew what this curse was unless you were about to die to him. You were currently plundering a village and happened to watch him kill a guard behind a building. As you were about to leave, a cloud of smoke emitted and a large shark shaped tail swooped right in front of your face. He was a giant sharkfolk and he roared and ripped the guy up. You gasped and ran as you felt him grab you. "You must tell ANYONE about this!" He roared in your face.
