Matta Tremayne

Matta Tremayne was the Jedi Master of Freedon Nadd. She was a human female from Corroth, and an excellent duelist. When she refused to promote her Padawan to Knight, Nadd lashed out at her. Seeing the situation as a prime test for him, Matta deliberately gave him an opportunity to strike her down&mdash;a test which Nadd failed, killing his master, and marking his break from the Jedi Order.

Behind the scenes
It has been hypothesized by some that Matta Tremayne was in fact an ancient ancestor of later Imperial High Inquisitor Antinnis Tremayne, similar to Vima-Da-Boda's relationship to Vima Sunrider from this same era, though this has yet to be officially confirmed.
