Breen

The Breen were a species native to the planet Breen in the Alpha Quadrant. They were a notable secretive race, often seen as an unknown factor as even their allies were not privy to a great deal of information on the race. During the Dominion War the Breen government, the Breen Confederacy, allied with the Dominion, following the conflict they retreated back into their own space. In 2383 the Breen attacked the Federation colony on Jestra V, signaling their entry into the Xindi-Suliban Alliance.
