The Breen established the isolated Breen Confederacy in the Alpha Quadrant (the quadrant of the Milky Way in which Earth is located, as well as the homeworlds of the Ferengi, Cardassians, and portions of the Klingon Empire and Romulan Star Empire). The Breen established outposts near the Black Cluster, according to the 1992 fifth season "Next Generation" episode "". They also established mining facilities consisting of Breen guards and slaves kidnapped from spaceships, such as Tora Ziyal, the half-Bajoran daughter of the Cardassian Gul Dukat, whose ship, the "Ravinok", had crashed on the planet Dozaria, which was controlled by the Breen, as established in "Indiscretion".
