Drovoer II was a Federation colony world located near the Cardassian border. It had a population of approximately eighty thousand, and was home to a large artists' retreat. Drovoer II was one of the worlds ceded to the Cardassian Union by the Federation-Cardassian Treaty of 2370. Its inhabitants agreed to give up their Federation citizenship and remain under Cardassian authority, and the Maquis subsequently used Drovoer II as a base for their campaigns. One such campaign involved an attempt to alter the timeline using the theories of Dr. Paul Manheim in 2373.
