In 2002 Commander Cold led a top secret mission to the ice planet Krysto. The purpose of the mission was to conduct rocket science research. The rumored nature of the top secret mission attracted a lot of attention from numerous hostile factions. Ultimately Blacktron launched an attack on Krysto that decimated the settlement. Any survivors were left-for-dead. 100 years later the descendants of the original survivors remain on Krysto using whatever they can find to stay alive in the hostile environment.
