Kurill Prime is a planet located in the Gamma Quadrant. 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. (DS9: "The Jem'Hadar") Given the number of lies Eris spun it is uncertain whether of not Kurill Prime is the Vorta's homeworld or just another lie.
