- "Nenn is the senior Master of the Theran Listeners—as close as we have to a leader."
- ―Taru Durn
Nenn was a male Oldtimer and senior Master of the Theran Listeners. He was taken by Abeloth and used as a way to turn the Oldtimers and the Theran Listeners against the Skywalkers and Khai who pursued her. When Skywalker cut Callista's personality out of Abeloth, Nenn was strong enough to take a lightsaber and kill himself, further weakening Abeloth and stopping the Theran Listeners from following her and freeing the Horn siblings from her grasp.
