Proserpina was one of the Core Worlds housing heavy industry companies such as Guided Technologies and Bulldog Enterprises. These factories, and many others, exploited the petrochemical and mineral resources of the planet directly and refined metals from the ores in the world were shipped to many other planets. After the fall of the Star League the world faced nearly constant raids by the Federated Suns. During one of these raids the defending DCMS forces used a nerve gas to destroy the invaders. As a result the planet's surface is mostly poisonous after combat during the Succession Wars; In fact two of it's five continents (Amerigo and Greater Harpago) are totally uninhabitable. In 3066, despite the years that have passed since the wars both the air and water on planet surface are still contaminated. Yet the rich minerals of the planet and well developed industry bring prosperity to it's inhabitants, even if they do need to wear environmental suits and breathing masks.
The location of Proserpina on the Federated Suns border insures that the DCMS has kept a strong defensive force in place on the world, as well as establishing an extensive network of refit and rearm points for defending troops. In addition to the military forces on world, the planet also hosts the University of Proserpina, a military academy that has consistently turned out high-quality graduates for the DCMS.
