Memit Nadill was a green-skinned, humanoid Jedi in service about 1000 years before the Sith War. His head was dotted with horns, and he had medium-sized tendrils coming out the back of his head, as well as a bony horn coming out of his chin. Memit Nadill was an advisor to Empress Teta, and assisted her in the Unification Wars, in which Empress Teta fought to unify all the planets in her system. When all but one planet, Kirrek, had been unified, Memit Nadill was joined by Jedi Knight Odan-Urr, and the two became very good friends.

Together, Memit and Odan left with Empress Teta's forces to launch an attack on the pirates on Kirrek to unite the worlds. On their journey, Memit Nadill learned the basics of Jedi Battle Meditation from Odan-Urr. The Battle Meditation turned the tide of the battle, and Memit Nadill and Empress Teta's forces were prosperous. Once the seven worlds had been united, Memit Nadill served Empress Teta as a security advisor and law enforcement officer.

Together, he and Odan-Urr helped to preserve the peace and protect the inhabitants of the seven worlds. He and Odan even saved Gav and Jori Daragon, two sibling space farers who were responsible for the discovery of the Sith Empire, and sensed their danger, of which he suggested they should leave the Empress Teta system, the Koros system, to find safety. Memit continued his work as a peacekeeper, ignorant to the fact that he had just sent the two siblings on a journey to the Sith Empire.
