The Zygerrians were a powerful people in the days of the Old Republic, before the Jedi Knights tore down their empire of slavery. When slavery was outlawed in Republic space, the Jedi Knights liberated countless beings from bondage, and the despicable trade the Zygerrians excelled in was pushed into the shadows of the underworld. Zygerrians are a humanoid species, with strong, angular features. They are very strong, able to easily dominate the weak when on equal footing. They are also quite cunning at ensuring they always maintain the upper hand in any situation.
A Zygerrian slavemaster who led the slaving operation on Kadavo, Agruss delighted in his superiority over his pathetic charges. Agruss flaunted his power freely, punishing and executing slaves at a whim to ensure no one every questioned his authority. The overweight Zygerrian hovered aloft on a repulsorlift chair, exuding an air of decadence. Agruss particularly delighted in tormenting Obi-Wan Kenobi, the first ever Jedi to be interred at his grueling facility.
A Kel Dor from Dorin, Plo Koon was among the wisest members of the Jedi Order, respected for his level-headed analysis of events and unflappable calm. Deeply concerned for life in all its myriad forms, Plo was especially devoted to protecting the clones under his command. He shared a special bond with Ahsoka Tano, whom he’d brought to the Jedi Order as a toddler. One of many victims of Order 66, Master Plo died at Cato Neimoidia when his wingmen shot down his starfighter.
Zygerria is a picturesque world with fortress-capped mesas that extend above windswept plains. Graceful brezak creatures catch the wind currents and soar effortlessly from butte to butte. The beauty of the planet hides the fact that Zygerria's cities were all built upon the backs of slaves. For thousands of years, Zygerria supplied slave labor the the galaxy; the Zygerrian Slave Empire became wealthy and powerful, as did those who exploited their chained subjects. After the Jedi Knights cracked down on the slave trade, Zygerria diminished. Its old fortresses and slave markets are still impressive edifices, though their luster has faded from time. Some Zygerrians are actively plotting a return to the old ways, and are finding eager allies in the Clone Wars.
