A Blood Ship is an unregistered marine vessel that transports criminals and DNA traders from port-to-port. They can also carry dead bodies, alongside any DNA that traders may be holding. Blood Ships are usually black, as they attract less attention. Unlike registered vessels, Blood Ships can be run by any person, Fire-Eyed or non-Fire-Eyed. Blood Ships generally follow a route through Blood Markets (legal and illegal), graveyards (legal and accidental) and Meadow Dweller habitats.
