Qizak belonged to the Nargon species, and he was a bio-engineered being crafted by the Qreph siblings to serve their purposes. During 45 ABY, he journeyed alongside the Qreph-contracted Mandalorians Scarn and Jakal to the Red Ronto situated on Brink Station with the intention of coercing Omad Kaeg into relinquishing his portion of the mining cooperative. However, when Han and Leia Organa Solo, who were in a meeting with Kaeg, exposed the Mandalorians' deception, the situation escalated into a violent conflict, leading to Scarn's demise, Jakal sustaining severe injuries, and Qizak suffering the loss of both of his arms. Han acquired one of the severed arms for a preliminary investigation to determine the biological nature of a Nargon.
