Depnen was a holographic male Yaderan baker created by Rurigan, a Yaderan who left his homeworld after the Dominion captured his world and changed the planet's society. The village created by Rurigan on Yadera II in 2340 was a recreation of all that he had lost. Depnen was a baker in the village.
By 2370, he was a good friend of Taya's mother and always saved the best loaves of greenbread for them. Shortly before her disappearance, Taya's mother was making a vase for Depnen. (DS9: "Shadowplay")
