- For the primary universe counterpart, see Athos IV.
Athos IV is a planet in the Badlands in the mirror universe.
After Terok Nor was destroyed by the Cardassians, General Miles O'Brien ordered the surviving Terran Rebellion forces to regroup at Athos IV. The planet had abandoned mines rich with fistrium, which Michael Eddington hoped would stop the Alliance from detecting the survivors. Worf was held on Athos IV at this time.
