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 legendary Jedi Master, Obi-Wan Kenobi was a noble man and gifted in the ways of the Force. He trained Anakin Skywalker, served as a general in the Republic Army during the Clone Wars, and guided Luke Skywalker as a mentor.
Ahsoka Tano, a Togruta female, was the Padawan learner to Anakin Skywalker and a hero of the Clone Wars. Alongside Anakin, she grew from headstrong student into a mature leader. But her destiny laid along a different path than the Jedi.
Level-headed and unflappably calm, Jedi Master Plo Koon is among the wisest in the Jedi Order. Deeply concerned for life of every form, Plo Koon is especially devoted to protecting the clones under his command. Master Plo shares a special bond with Ahsoka Tano for finding her as a baby.
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.
