Viull "Scut" Gorsat was a male Yuuzhan Vong who served with the Wraith Squadron. During the conflict known as the Yuuzhan Vong War, Gorsat was apprehended by forces of the New Republic and subsequently entrusted to Mulus Cheems and his spouse, who nurtured the Shamed One offspring as their own.
By the year 44 ABY, Gorsat had become an operative within Wraith Squadron, a clandestine intelligence unit operating under the banner of the Galactic Federation of Free Alliances, going by the moniker Scut—a designation his adoptive mother found distasteful. When participating in missions with his team, he utilized a neoglith masquer, a personalized modification of the standard Yuuzhan Vong cloaker, to conceal his true appearance and resemble a human. A distinguishing characteristic of his neoglith masquers was their perpetual smiles, which he could only suppress with significant conscious effort.
During the mission aimed at exposing the corrupt GA General Stavin Thaal as a participant in the notorious Lecersen Conspiracy, Scut frequently clashed with the seasoned member Voort saBinring. saBinring initially harbored mistrust towards Scut due to his heritage; Scut, conversely, expressed dissatisfaction with saBinring's performance as a member, citing the Gamorrean's excessive emotional reactivity and lack of logical reasoning, leading to frequent disagreements with the squad's commander, Bhindi Drayson. Scut divulged these sentiments directly to saBinring following Drayson's demise on Vandor-3.
On the world of Kuratooine, where Wraith Squadron ultimately brought General Thaal to justice, Scut mended his fractured relationship with saBinring, who, by that point, had assumed leadership of the squadron (much to Scut's annoyance). The Yuuzhan Vong revealed to the Gamorrean that he had actually admired him as a role model, ever since he rescued Mulus Cheems, the man who would later raise him with the previous Wraith Squadron, back in 13 ABY. SaBinring, after overcoming his own internal struggles (stemming from his act of mercy towards his comrade Hohass "Runt" Ekwesh in 29 ABY), finally embraced Scut as a full-fledged member of Wraith Squadron.
Scut played a crucial role in the successful apprehension of Thaal; he enlisted Dr. Cheems' assistance in crafting counterfeit crystals to lure Thaal to Kuratooine, exploiting his avarice. Scut also personally designed a full-body neoglith suit for fellow Wraith member, Turman Durra, disguising him as a member of a fictional indigenous species of Kuratooine, which served to convince Thaal that the nonexistent valuables, supposedly provided by this fabricated species, would greatly benefit him. By the mission's conclusion, Thaal was placed under arrest for impersonating himself, due to alterations made to his genetic structure in preparation for his retirement.
Before Thaal's capture, Scut confided in saBinring that his adopted name, Viull Gorsat, was not his birth name, but rather a name he chose himself, considering it a prestigious name within Yuuzhan Vong culture.
