Second Race to join the Federation since the end of the Borg War, when contact was re-established the world of Andoria was found to be under the control of the Borg. However, for reasons unknown, the planet was never completely assimilated. The Defiant arrived to find the atmosphere of the planet in a precarious state—the Borg nanites and nature itself were warring for domination. If the environment were pushed even an inch in the wrong direction, the planet would become uninhabitable. At least one atmospheric processor was put into operation with several more in various states of repair.
