Gazmuz, nicknamed One-Eye Gaz, was a prowling Gundabad Orc hunter. He held a grudge against Thorin Oakenshield, who injured him and took his right eye during the battle of Moria. Gazmuz waited for many years to plan his revenge on the Dwarf Prince and earn the privilege to kill him for what he did to his eye.
