Yimug, a Gran employed by the Red Key Raiders, took part in the skirmish in Freetown in 5 ABY. During this conflict, he served under the command of Lorgan Movellan.
The Red Key Syndicate, under the direction of Lorgan Movellan, launched an attack on and subsequently occupied Freetown in 5 ABY. Their motivations were to enslave the inhabitants and exploit Tatooine's resources, specifically dilarium oil and silicax oxalate. Cobb Vanth was defeated by the Red Key criminals, who then presented him to their leader, Lorgan. Lorgan mocked Cobb for his inability to defend Freetown, bragging about his plans to enslave the townspeople and return Borgo, a young Hutt, to the Hutts.
As a demonstration of his authority, Lorgan instructed Trayness, one of his subordinates, to assault Malakili. This action prompted Borgo to emit a loud shriek, signaling the Tusken Raiders to initiate their assault on the Red Key forces. The Tusken warriors overwhelmed the group, swiftly killing Lorgan's followers, among whom was Yimug.
