Vereshvar was a Cardassian term that was used to describe the gradual decline of Cardassia as a civilization. The word was used to relate to when the Cardassian people exhausted the natural resources of their homeworld. In order to survive, the military took control of the government and sought to expand the Cardassian Union, at the cost of the very culture they sought to preserve. (Decipher RPG module: Aliens)
