Telfrey, a world located in the Trans-Nebular sector of the Mid Rim, was the original planet of the Telfreyans, a sentient species. During the Imperial Period, Humans also resided there. Two such Humans, Tay Vanis and Yom Argo, departed Telfrey to become spies for the Rebel Alliance. These two later came back to Telfrey to look into claims of heightened Imperial presence, which led to an outright revolt on Telfrey. The bombardment that followed as the Empire's reaction made the entire planet unable to support life. Later on, during the Nagai–Tof War, the Tofs created a strongly defended installation on the surface of Telfrey.
