Gray Nebula: Crewmen, Con-Men, and Lawmen
A class sourcebook for White Star: White Box Science Fiction Roleplaying, adding three compatible classes: Crewman, Criminal, and Lawman. Crewmen serve as mechanics, gunners, navigators, security officers, and other starship support personnel, while Criminals include thieves, gang members, con-men, and other outlaws. Lawmen enforce laws as constables, investigators, marshals, or agents, with options for former officers such as bounty hunters and private investigators. Each class is divided into specialized Roles, and nine fully detailed NPCs include backgrounds and adventure seeds for use in a campaign.
