P3R-118 is a planet in the midst of an ice age. Administrator Calder and his people lived in comfort in a domed city with no unemployment and no crime, while those chosen as workers were given a memory stamp and labored in the underground power facility, unaware of the city above. The planet offered advanced metallurgical and chemical technologies, and trade was proposed with the SGC in exchange for stargate technology. However, when SG-1 was detained and forced to join the underground workers, negotiations ended, and when SG-1 released the workers, the city dwellers were left to find a new source of labor and power to support themselves.
