Teplan homeworld
The Teplan homeworld was an inhabited planet in the Teplan system of the Gamma Quadrant, just outside Dominion space. It was the home planet of the Teplans. 

The planet had an advanced civilization until the mid-22nd century. The Teplans built cities, traveled to neighboring worlds, and believed nothing was beyond their abilities. But when the Teplans defied the Dominion, the Jem'Hadar destroyed their world and introduced the blight into the population. 

By the late 24th century, the Teplan cities lay in ruins, their civilization destroyed. In 2372, Julian Bashir visited the planet and found a way to stop the blight. This turned out to be an in-vitro vaccine that would allow future generations to be immune to the blight. ()
