Dutchman

The Dutchman background story (Not from the game)
The Flying Dutchman (Dutch: De Vliegende Hollander) is a legendary ghost ship that can never make port and is doomed to sail the oceans forever. The myth is likely to have originated from the 17th-century golden age of the Dutch East India Company (VOC). The oldest extant version has been dated to the late 18th century. Sightings in the 19th and 20th centuries reported the ship to be glowing with ghostly light. If hailed by another ship, the crew of the Flying Dutchman will try to send messages to land, or to people long dead. In ocean lore, the sight of this phantom ship is a portent of doom.
