In spite of meeting this Jedi Master for a brief time, I found he is one of the likeable characters in the "Star Wars: Knights of the Old Republic" game.
Nemo: a male Human Jedi Master during the Jedi Civil War.
Elderly though he was when Revan first met him, Nemo knew well about the situation on Dantooine. Yet he played Pazaak in the early morning hours with Twi'lek Aratech employee, Karal Kaar. Their disputes during Pazaak were far from retort.
Mention of Aaron Klann's true identity was kept a secret from him. Only Nemo, the other Jedi Masters, and Bastila knew who he really was, as Aaron trained in the ways of the Force.
On his last mission, the Council assigned Nemo to investigate the Rakatan Ruins, to the east of the Enclave. Inside the ruins, Nemo failed to overcome the temple's defenses and was slain by one of the guardian droids. There was a chance for the Jedi's remorse.
