A Cardassian Union world housing a Dominion cloning facility, the first target struck by Legate Damar's forces when he turned against the Dominion in 2375.
Rondac III is a planet in Cardassian territory where the Dominion maintained a cloning plant. It features in the Deep Space Nine episode The Changing Face of Evil (2375).
Damar, nominal leader of Cardassia, has grown bitter at the Dominion's contempt for his people and at the concessions made to the Breen. He quietly plans a revolt, and its opening move is an assault on the Rondac III facility.
As the Dominion celebrates the Breen attack on Earth and the destruction of the Defiant at Chin'toka, Damar's speech reaches every Cardassian world. He announces that his troops are attacking Rondac III and calls on all Cardassians to rise against their supposed allies.
