Scraggs was an Englishman aboard the Fleiger Hollander who conspired against Captain Vanderdecken along with Sindh and Jamil. He wanted to kill the captain with a stiletto.
Upon discovery of his disloyalty, Vanderdecken hurled him over the side of the ship.
Scraggs, Petros, Sindh, Vogel, and the Captain were eventually cursed by the Angel to roam the seas for eternity.
