This Datacron unlocks the Codex Entry - Galactic History 33: Dromund Kass
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:
Once an outpost of the ancient Sith Empire, the planet Dromund Kaas now presented a refuge to the Empire's weary survivors after their long exile from Korriban. Upon landing, the Emperor addressed the populace, promising them that from this world, a new civilization would grow to eventually crush the Republic.
The challenges of colonizing such a wild planet were soon evident. Dromund Kaas's jungles were untamed, full of dangerous predators. To ensure order and discipline, military service became mandatory for non-Force sensitives. Imperial citizens took pride in this duty, knowing they were defending the future of their people.
Before withdrawing into isolation, the Emperor established a Dark Council to oversee the Empire and control the hierarchy of the Sith. He is said to have conducted many dark side rituals and experiments that affected the planet itself, leaving Dromund Kaas storm-wracked to this day.

This Datacron is located in the Nikto Sector of Nar Shaddaa and is only available to Republic Players. To reach this Datacron head over to Nar Shaddaa and take a speeder to the Nikto Sector. Once you arrive head to the far northwestern section of Nikto Sector, right where I am in (Screenshots 1 & 2). You will want to jump up on top of the boxes in (Screenshot 1) and then onto the large crate in front of the boxes. Once you're on the crate continue up the boxes to the east and jump across to the next crate (Screenshot 3). If you're having trouble making this jump, jump from the single crate, not the double stacked ones. The single crate will make it so you don't hit your head on the ceiling.
From the crate continue east by jumping onto the awning. Run across the awnings until you reach the second of the large metal things that connects to the awning holding it up (Screenshot 4). Hop onto this piece of metal and run up the tightrope until you can make it onto the large pipe at the end. Get onto this pipe and run across it over to where you originally were on the awnings (Screenshot 5). From here you will want to jump onto the pipe east of you and up onto the next pipe which is to the east as well.
Note: If you're having trouble with this jump, take it on an angle
From here run further east until you come to a small sign (Screenshot 6). This is one of the more difficult jumps since the area you need to land on is so small. But once you make it jump up onto the large a wee bit north and follow it around a bit east and south. From here you should be able to see the Datacron (Screenshot 7) , only a little bit more and it's ours! To reach it from where I am standing in Screenshot 7 turn a bit to the north and look down off of the column you are on (Screenshot 8). You'll see a small rope that leads to another column and then a rope from that column which leads to the Datacron. You're almost there so don't screw up now!
A final tip, don't bother jumping up to the Datacron's column. Grab it from the rope, why take the risk when you don't have to?
