Surrounded by the natives of Kalimar, Maura and Travis Silverthorn are cut off from the rest of the crew. The Night Riders explain their murderous intentions against miners of the glowstone: it is the energy source that powers their entire asteroid, and worse yet, it will quickly make humans exposed to it just as blind as the Night Riders themselves. Travis discovers this first-hand. But can the human race be trusted to keep away from Kalimar?
