The system is made up of two planets, Abrion Major and its smaller twin sister Abrion Minor. Major has always provided numerous raw materials that have lead to rapid expansion for its rulers, while Minor provided numerous creatures that proved useful in transporting goods.

Long before galactic hyperspace travel came about, a race known as the Sakar dwelled here, mastering crafts that made them the envy, and masters, of many local planets and systems. Tales of the Sakar technology reached the ears of other local groups who wanted the technology for themselves. When this technology was refused to some groups, a sector-wide war broke out. At first the Sakar held the advantage, but they were eventually overwhelmed by superior numbers and the loss of their technological lead. After many years of battle, most of the system lay in ruins, with the Sakar race extinct and Abrion Minor a dead planet.

Today, life has returned to normal in the system, but the scars of war remain. Although the present day Sakar are a technologically backward race because of the war, they have made great strides in repairing their planets and adapting to other galactic civilizations. Some life has returned to Minor, although the planet is still inhospitable to most beings. And Major is slowly becoming the central hub of galactic trade for the entire sector, which will immeasurably increase the benefits for all who call Tau Sakar home.
