Ozolu City was a Cardassian city. In the 2360s, the Bajoran splinter group Kohn-Ma was reputed to have sabotaged a power generation station at this city. This station was the primary power source for a mining station. Informants believed the attack was an attempt at warning the Cardassian authorities from maintaining the use of their mining facilities. An intelligence report of this event was stored in the Bajoran Intelligence net, which was accessed in 2369 by Major Kira Nerys when she was looking into Kohn-Ma activities. (DS9: "Past Prologue") This city was only mentioned in writing.
