Gralack was a location in the Outer Rim Territories. Several structures were located on Gralack, including a theater where the actor Tunga Arpagion performed.
In a theater on Gralack, the Clawdite shapeshifter Tunga Arpagion performed a play that retold the events of the Mutiny on Mon Cala. Imperial stormtroopers interrupted the performance, claiming it was illegal and treasonous. As Arpagion and the other actors tried to escape, Luke Skywalker confronted the troopers, who believed he was the shapeshifter. Luke cut the stormtroopers down with his lightsaber as Leia Organa and Han Solo let the actors escape, recruiting Arpagion for a mission to Shu-Torun.
