Rurigan was a male Yaderan. He lived on Yadera Prime until it was conquered by the Dominion in 2340. He apparently possessed some knowledge of holographic programming and design. Unhappy with the changes brought on by the Dominion, he decided to move to one of the planet's colonies, and created a holographic reproduction of his village complete with a population. The holographic generator was disguised as the village's reactor. By his own admission, he created the program himself and made it possible for the villagers to reproduce if they wanted.
In 2370, when Odo and Lieutenant Jadzia Dax landed on the planet, the holographic figures were disappearing, probably to the age and general wear and tear on the machine which Dax was able to fix to restore Rurigan's world. (DS9: "Shadowplay")
