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:

Naga Sadow’s attempt to conquer the Republic in the Great Hyperspace War had failed. After the battle at Primus Goluud, he led the limping Sith fleet back to Korriban, only to find an old enemy waiting for him. His rival Ludo Kressh, believed dead, now commanded a fleet of his own.

The two Sith Lords fought furiously, only to be interrupted by the Republic fleet, which had pursued Sadow through hyperspace. The Republic began to attack the Sith forces, quickly gaining the upper hand.

Sadow took desperate measures. He forced one of his captains to ram Kressh’s flagship, killing his rival once and for all. Left with only a single vessel and a crew of slaves, Sadow escaped the battle and fled to the remote jungle world of Yavin Four. Sadow then placed himself in a long stasis, still dreaming of a Sith golden age."
