Breen is the seventh planet of the binary system of the same name and is the home and capital of the Breen Confederation. The planet is very cold, thanks to its location in a cold zone and temperatures below -70 ° C. There are frequent precipitations of liquid hydrocarbons. This world also lacks a hydrosphere, although it has oceans of liquid methane that cover half the planet's surface. The only mainland is the two vast rocky continents where the advanced Breen civilization evolved. They have an extensive network of shipyards in orbit.
