Durnar was a Jedi Knight who fought for both the Jedi Order and the Galactic Republic throughout the duration of the Clone Wars.
Durnar, who possessed Force-sensitive abilities, received training from the Jedi Order in the art of wielding the Force. He eventually achieved the status of Jedi Knight. As the Clone Wars broke out between the Galactic Republic and the Confederacy of Independent Systems, Durnar managed to stay alive until the war's last year, at which point he was sent to the front lines of Saleucami under the leadership of Jedi Master Oppo Rancisis.
Durnar perished in battle against the Morgukai Shadow Army during the conflict. Sian Jeisel, a fellow Jedi, grieved for her fallen companion during Master Rancisis' funeral, along with the other soldiers who had fallen on the battlefield.
John Ostrander theorized that Durnar was a Yaka and was born in 43 BBY.
