Kurill Prime

Kurill Prime is a planet located in the Gamma Quadrant.

Kurill Prime was the site of the Dominion's largest Vorta cloning center in the quadrant. The original Jasis and several of her subsequent clones were from the planet.

Eris mentioned Kurill Prime as the homeworld of the Vorta and that it was conquered by the Dominion in 2370 as part of her cover story when she attempted to infiltrate the Alpha Quadrant in that year. 
 * Given the number of lies Eris spun it is uncertain whether of not Kurill Prime is the Vorta's homeworld or just another lie.
