Trivas system
The Trivas system was a star system located in Cardassian space until 2372, but abandoned by the Cardassians in that year. It was no more than three light years from the Bajoran system. The system was the location of the station Empok Nor. 

The system did not feature prominently in the Dominion's plans for the Cardassian Union. ()
