Yadera Prime

Yadera Prime is a planet in the Gamma Quadrant. It is mentioned in the episode "Shadowplay" (DS9) that the Dominion invaded this planet somewhere around 2340.

A Yaderian named Rurigan explains how he fled the planet where the Dominion destoyed all life as he knew it. He then set up a holographic village on an unamed planet which in the episode was said to take place some 30 years ago and this episode was set in the year 2370 or stardate 47603.3.

When Dax and Odo land on the planet after detecting strange enery readings, it turns out the holographic projector is failing, resulting in the disappearance of 22 people. Odo and Dax offer to repair the device which is eventually achieved, restoring the village and all it's people including those that disappeared.
