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:

Led by their new Emperor, the survivors of the Sith Empire had left Korriban aboard a small fleet following the Great Hyperspace War. There was no place in known space they could hide from the Republic–and so, undaunted, they fled into the unknown regions of the galaxy. Where the old Sith Empire had often been divided by rivalries, the survivors were now united, both by their desire to find a new home and by their anger at the Republic that had sought to destroy them.

For decades, the fleet wandered among the stars–until one day, a scout vessel returned to the armada with incredible news. Either by luck or by the esoteric designs of the often-silent Emperor, the Sith had rediscovered a long-lost outpost world: the jungle planet of Dromund Kaas. Absent from any star charts, Dromund Kaas presented a perfect refuge where the Sith Empire could rebuild and plan its revenge."
