Garnac's hunting guild was made up of a group of Trandoshan hunters during the time of the Clone Wars. The guild would travel around the galaxy including to systems such as Felucia, capturing unknowing victims and delivering them to Wasskah in order to be hunted. Occasionally, the Trandoshans would capture Jedi Padawan.
Around 21 BBY, Trandoshan Lo-Taren was sent to Felucia on a mission to capture new victims to be used in the hunt. Lo-Taren arrived at the scene of an ambush of a droid base. There, he spotted and captured Ahsoka Tano to be brought back to the Trandoshan moon to be hunted.
Once arriving on the Trandoshan moon, the Trandoshans dumped their prey onto the beach of Island Four and opened fire on them, killing a majority of the prisoners while a few escaped. Ahsoka met up with a group of other Padawan who had been captured and worked together to escape the moon. They took down a drop ship carrying new prey and found the Wookiee Chewbacca on board and brought him with. Chewbacca built a radio which caught a signal from Kashyyyk while the Padawans and Chewbacca went to take down the Trandoshan fortress.
While the Padawans and Chewbacca fought off the Trandoshans on the flying fortress, General Tarful and several Wookiee soldiers, being transported aboard the Halo. The Wookiee reinforcements joined in the attack and by the end, all of the Trandoshans except for Krix, Ramy and Smug had been killed and the guild had been disbanded.
