Stars Without Number
Polychrome is named for the gases that light brilliant flares of color across each evening sky. Nowadays nothing lives on the surface of the planet except salvagers in sealed exploration vehicles and the remnants of alien Zadak raiding parties. The insectile Zadak attacked Polychrome shortly after the Scream, detonating a number of atmospheric biotech devices that poisoned the planet irrevocably. The spread of the toxin was slow enough to give some survivors time to seal some underground shelters that grew into the warren-cities that dominate Polychrome today. A degenerate Exchange Consulate splintered into multiple corporations that have effective rule over the planet now, contested only by a “revolutionary” movement that’s led chiefly by amoral opportunists. Polychrome cyberware is the finest in the sector, however, and the need to compensate for long-term exposure to trace toxins has made its development and implantation a prime industry.
The powerful Kuroi Hoshi crime syndicate is the Exchange Consulate’s chief competition, and sometime associate, for sway over Polychrome’s million or so subterranean inhabitants. One of Kuroi Hoshi’s shatei-gashira recently floated a 200K credit loan to a “doctor” from off world.
