A religious group based on the teachings of the desert prophet Mamoud. Blue Crescent Adherents typically shave their hair bald, tattoo a blue Crescent on their foreheads, give up all personal property beyond what they can carry, and must visit the major locations that Mamoud once lived in the Badlands during their life. They are noted for being generous, friendly, and often volunteer for civic duties and charities, but are not pacifists. Blue Crescent Adherents can be found serving in the military of many of Terra Nova's Leagues.
