A Bajoran who works for the Cardassian occupation on Terok Nor, choosing women from refugee camps to serve as comfort women and acting as Gul Dukat's personal go-between.
Basso Tromac appears in Wrongs Darker Than Death or Night, played by David Bowe.
When Kira Nerys uses the Orb of Time to visit 2346, she is caught up in one of Basso's selections at a refugee camp, where he picks out Bajoran women, among them her mother Kira Meru, and ships them to Terok Nor. He promises that their families will receive extra food and medicine and treats this as generosity.
On the station Basso manages the women's quarters and attends closely to Dukat's wishes, moving Meru into the prefect's rooms once Dukat takes an interest in her. He is contemptuous of other Bajorans and quick to punish Kira, who is using the name Luma Rahl, when she defies him, having her thrown out of the comfort women's quarters.
