A Cardassian world whose military academy employed Aamin Marritza as an instructor, a detail of the false trail he lays in the episode Duet.
Kora II is named in Duet, in which a Cardassian passenger arrives at Deep Space 9 suffering from Kalla-Nohra, a condition contracted only by those present at a mining accident at the Gallitep labour camp. Kira has him arrested as a war criminal.
The man gives his name as Aamin Marritza, a filing clerk at Gallitep who has spent recent years teaching at the military academy on Kora II. Enquiries there and elsewhere seem to show instead that he is Gul Darhe'el, the camp's commandant, and he begins to boast of his atrocities.
Further checks reveal that Darhe'el is dead and that the prisoner had resigned from his post on Kora II and altered his face in order to be caught. He really is Marritza, seeking a trial that would force Cardassia to admit its guilt.
