Allat Za served as the Chieftain of the Quarren species during the initial contact between the people of the Quarren homeworld of Dac and the Galactic Republic, an event that occurred more than 120 years following 4500 BBY. When Dac was presented with the choice of joining the Republic, the Mon Calamari, another sentient species residing on Dac, were in favor. However, Za was against joining the Republic, compelling the Mon Calamari king then in power to instead declare Dac an independent state in alliance with the Republic. Although the Quarren considered Za's accomplishment a triumph, they gradually felt more and more sidelined by the Mon Calamari as time passed.
The 2015 sourcebook titled Strongholds of Resistance for Star Wars Roleplaying, released by Fantasy Flight Games as part of the Star Wars: Age of Rebellion roleplaying game, included a mention of Allat Za.
