Durkani was a member of an unknown race in the Eridani Sector attempting to uncover a conspiracy within his government about aliens.
Originally a member of a government agency, Durkani had become aware of a conspiracy to hide alien interference on his world. He promptly left the agency a set out on his own to gather evidence and expose this "conspiracy." He spent many years on his personal crusade. A few years before encountering the Excalibur, he met a young woman named Lyssa who, after much convincing, joined him in his search for the aliens. They broke into a room apparently containing evidence, when two people walked in; they fought and killed them and discovered something even more strange. This convinced both of them that their only means of finding out what it meant was to get closer to the problem. Durkani stole a ship and piloted it out of the system to find the "Aliens." He succeeded.
Taken in by the Excalibur, he took a human hostage, wanting to take him back as proof, but he was prevented from doing so by Captain Gideon and John Matheson. While in prison his companion Lyssa apologized to him for not believing him before. Gideon offered to hear their story that humans had been interfering with their world. Durkani, hearing Gideon's words, believed that the captain really didn't know about any interference. Bringing with him pictures and objects, he explained how and why his government had been covering up alien interference. Durkani was surprised when Gideon recognized the objects and the familiarity of the story, but was completely unaware of any involvement with their world.
Then Kendarr arrived wanting both Durkhani and Lyssa handed over for execution. When Gideon brought him to them, Durkani believed that he had been sold out by Gideon and immediately took Kendarr hostage and threatened to kill him. After Gideon regained control, Durkani and Lyssa were allowed to leave with Durkani threatening expose the truth. His fate after Gideon exposed their government’s lies is unknown.
