In 2372, Major Kira Nerys got word from her old friend Razka Karn that there might have been survivors, and that he had reason to believe that they were on Dozaria. After Legate Dukat was forced to go with her, she took a runabout to the planet and found the remains of the Ravinok. Just outside the ship, she found the burials of the crew members who had died in the crash, both Cardassian and Bajoran. The next morning, Kira and Dukat found the prison camp and infiltrated it, finding Dukat's daughter Tora Ziyal. Kira discovered that her friend, Lorit Akrem, had died two years earlier.

This planet's quadrant of origin is inferred based on its proximity to the Breen system and the Cardassian Union, whose positions were seen in the star chart appearing in the Star Trek: Picard episode "Maps and Legends".
"doe-zar-EE-uh" was the pronunciation for the Dozaria system's name from the script pronunciation guide.  The planet was not named in the episode; it was named by StarTrek.com and the Star Trek Encyclopedia (4th ed., vol. 1, p. 217).
In "Indiscretion", this planet was represented via use of filming location Soledad Canyon, which required the shooting company to undergo extreme weather conditions. "It was brutally, brutally, brutally hot out there in the rock quarry," noted Director LeVar Burton. The site included a lot of very fine gravel that looked like sand. "There was this huge, three-story mound of gravel in the quarry," Producer Steve Oster reported. Also, the production team added sand, in order to cover up the sides of two massive set pieces that represented parts of the Ravinok's hull. (Star Trek: Deep Space Nine Companion (pp. 275 & 276); Star Trek Encyclopedia (4th ed., vol. 1, p. 217))
There were fears over landslides in Soledad Canyon, which made burying the pair of set pieces difficult. The risk was specifically with the huge mound of gravel. "If you went up to the base of it and put your foot in it, part of it would come down," Steve Oster remembered. "There was a lot of concern about that, and while construction was going on, we were constantly aware of it." Ultimately, the mountain stayed put and didn't collapse. (Star Trek: Deep Space Nine Companion (pp. 276-277))
Due to the concerns regarding landslides, interior scenes set on Dozaria, such as in an underground mine, were filmed at Paramount's soundstages. The mine was additionally illustrated in a concept sketch by John Eaves, dated August 1995. (Star Trek: Deep Space Nine Companion (pp. 277 & 275))
The use of a filming location to depict Dozaria in "Indiscretion" pleased Ira Steven Behr. He enthused, "It was nice to be on location for that show. I thought it worked." (Captains' Logs Supplemental - The Unauthorized Guide to the New Trek Voyages, p. 107) He also described it as a "nice location."
