Brentaal League

An ancient association of planets that existed in the 3,000's BBY, known for its colonization of hundreds of worlds. The League had extended its hyperlane network to the Expansion Region by 4,020 BBY. They established the first human settlement on Muzara circa 4,000 BBY, with the intent of starting a lucrative farm industry. In the process they sparked a diplomatic war with the native Muza. The League's sphere of influence began to wane soon thereafter.

It is a symbol of pride on Brentaal to this day, though critics have referred to it as an "instrument of imperial conquest."
