Codex entry
"This datacron holds unheard of power and knowledge collected by an ancient race. You access its power and discover writings which are clearly only one small piece of a massive galactic history:

''Trained at the Jedi Temple on Ossus centuries after the Great Hyperspace War, Freedon Nadd was a powerful but temperamental Padawan. When denied promotion to the rank of Jedi Knight, the enraged Nadd struck down his Master. He left the Jedi and began to study the powers of the dark side.

''Although Nadd learned much from a Sith holocron, he craved more. Nadd traveled to Yavin Four where he encountered the Massassi, savages who were once servants of the Sith Lord Naga Sadow. Nadd defeated them easily, and the awestruck Massassi took him to Sadow, who rested in a suspended animation chamber.

''Unaware of the Sith Empire rebuilding itself on Dromund Kaas, Sadow believed Nadd was the acolyte he had been waiting for. But he underestimated Nadd’s craving for power, and Nadd soon killed Sadow and left Yavin Four behind. Nadd settled on the distant world of Onderon, becoming a legendary tyrant."
