|Breen - Class P - Breen Confederacy/Dominion
Location: Breen system, Alpha Quadrent
Affiliation: Breen Confederacy/Dominion (formerly)
Native Species: Breen
Gravity: 0.7 G
Breen is the homeworld of the Breen and their government.
The planet is the seventh in the Beta Epsilon-Venturi binary star system located near the border of the Alpha and Beta Quadrants. Thus, it is situated in a region of space between the planet Ferenginar and bordered the Romulan Star Empire. The Breen homeworld itself is highly frigid and cold due to the remoteness from its twin stars with temperatures never going above -70 degrees C. Furthermore, liquid hydrocarbons typically fell from the sky as rainfall. This highly hostile environment meant that no lifeform that lived on a Class M planet was capable of surviving on Breen without some form of advanced life support equipment. This world also lacks a hydrosphere though it did possess liquid methane oceans that covered half of the planetary surface. The only landmasses are two large rocky continents which dominated the Breen surface. Its known that the Breen homeworld had an extensive web of shipyards in orbit around their world.
History and politics
Even by the 24th century, much was still unknown about the Breen and their otherwise politically nonaligned government, known as the Breen Confederacy. The Federation, however, had limited knowledge of the Breen and was aware of Breen outposts located near a black cluster in 2368. In 2370, the Breen participated in a palio held at Deep Space 3, during which the Ferengi attempted to bribe the Breen pilot into throwing the race. In 2373, the Breen settlements on Portas V near the Demilitarized Zone dealt with the Maquis, supplying them with cold-storage units. It was noted by Ezri Dax in 2375, when captured by the Breen on a planet in the Goralis system, that they were a long way from Breen space. Other species like the Ferengi had developed closer ties with the Breen by the late 24th century, as both species conducted trade negotiations in 2373. Breen privateers during the 24th century would often conduct indiscriminate raids against other Alpha Quadrant species. This includes the Breen attack and capture of the Cardassian transport Ravinok in 2366. The survivors of that attack were used for slave labor in the Breen operated dilithium mines on Dozaria. (DS9: "Indiscretion") In 2368, Starfleet feared the Breen might have attacked the science vessel SS Vico. Breen privateers also raided the Bajoran colony of Free Haven in 2372; they were, however, successfully driven away by the USS Defiant.
Alliance with the Dominion
The Breen may have been influenced to join the Dominion by a Changeling impersonator in the Confederacy's government, as an unidentified Breen was seen in Internment Camp 371, where several people who had been replaced by Changelings were placed.
Shortly after joining with the Dominion, the Breen attacked Starfleet Headquarters on Earth in the raid on San Francisco. A short time later they assisted Dominion forces in breaking the lines at Chin'toka. Under orders from the Female Changeling they allowed the escape pods to carry the Federation survivors to safety. This major battle, known as the Second Battle of Chin'toka, was won by the Dominion thanks to a unique Breen weapon, a form of energy dampening weapon system which could completely drain all the main power systems of a starship. Both of these defeats dealt a huge blow to the Allies' morale. The only ship immune to the Breen weapon was a Klingon Bird-of-Prey, which serendipitously survived thanks to an adjustment the chief engineer had made to the ship's tritium intermix in the warp core. Although the Klingon fleet was able to make the needed adjustments against the weapon, the Federation and the Romulans were still unable to defend against the Breen. When the Federation finally did create a defense against the energy-dampening weapon, they would force the Dominion fleet to retreat. Breen Thot Pran expressed an extreme distaste of surrender, and would require the reassurance of the female changeling that they were not surrendering, but were instead regrouping and attempting to redouble their shipbuilding and replenishment efforts.
With the necessary counter measures against the Breen's energy dampening weapon obtained, the Federation Alliance was able to go on the offensive once again, choosing to invade Cardassia Prime itself. In hopes of boosting the Breen's will to fight, the Female Changeling offered them control of Earth and Romulus if they succeeded in winning the battle. During the Battle of Cardassia, the Breen were still able to inflict major casualties on the allies, even without the use of their energy dampening weapon. Up to a third of the allies' entire fleet was destroyed during the battle, including the Romulan flag ship. The Breen continued to fight with the Dominion until the end, demonstrating a willingness to die for the cause that matched that of the Jem'Hadar. However, when the Cardassian forces switched sides mid-battle, the Dominion and Breen were forced to withdraw to Cardassia Prime. After Odo convinced the Female Changeling to surrender, the Dominion War ended. As allies of the Dominion, the Breen leaders were present during the signing of the Treaty of Bajor.
