Civilizations stand and fall, not by might of arms, but by its cosmopolites - the ordinary Citizens and Scholars who make up most of the population. This Traveller sourcebook provides new options and possibilities for characters who have followed the Citizen or Scholar careers, including information on how to build a network of Allies, Contacts, and Patrons that can be called upon at any time, how to approach their own societies and fellowships for funding and resources, how to attend University or Medical School, explore brand-new career choices, and continue their research, even while travelling the galaxy.
