Lorenn was a Jedi Master of the male persuasion (male) who operated a recruitment facility located on the moon of Nar Shaddaa. He enlisted the Mon Calamari confidence trickster Languss Tuno and accepted him as his Padawan; however, Tuno eventually forsook his Jedi training and departed from the Jedi Order, absconding with Lorenn's lightsaber.
His Padawan, Languss Tuno, described him as aloof towards his students, and also as a demanding and rigorous instructor. Isaac, the "Force Master" who later taught Languss, stated that Lorenn's teaching methodology involved the inflexible imposition of directives and a commitment to established Jedi principles and practices, rather than permitting his students to evolve and develop independent thought. This approach, in certain instances, caused Padawans possessing latent abilities inaccessible through conventional Jedi instruction to leave.
