Prana was a Bajoran man and a Corporal in the Bajoran Militia.
When Quark and Rom were detained in the Gallitep labor camp where Prana was stationed, Prana initially neither took a side with Colonel Mitra and Wyte, or Argan and Jessel. However, once Argan and Jessel were murdered, Prana shot Mitra and escaped the camp with Quark and Rom. (DS9 novel: The 34th Rule)
