In this guide, we provide you with maps and complete directions to each of the datacrons hidden throughout Korriban in The Old Republic. Datacrons are ancient devices that will provide you with permanent stat boosts, or matrix shards that can be combined to create items for your 'relic' equipment slots. On Korriban, there are a total of 2 stat boosts, and 1 matrix shard - complete details on how to find each can be found below.
This datacron is located in an area called the Lower Wilds which you can reach via the taxi just outside of the Sith Academy. Your class quests will send you to this area around level 4 or 5, so there's no need to make a special trip to the Lower Wilds if you're just starting out as a Sith Inquisitor or Warrior.
From the Lower Wilds taxi, follow the trail that naturally leads you to the right, past the research outpost, and past the holocommunicator that offers a side quest.
This datacron is in a deceptively simple location. To reach it, head to the shuttle that takes you to the fleet station (just past the entrance to the Tomb of Tulak Hord). Directly across from the shuttle, you'll see a metal platform overlooking the Lower Wilds area. From that platform, look to your right behind the wall, and you should easily spot the second datacron on Korriban.
The third and final datacron on Korriban is found in the Antechamber of the Tomb of Tulak Hord. The main tomb entrance is located down the path leading to the fleet station shuttle. For Sith Inquisitors and Warriors, your class quests will send you to this area around level 7-8.
Travel through the first interior area of the tomb until you emerge in a large courtyard area. As soon as you pass the medical droid, follow the path leading to your right, down a small hill, and through the opening in the wall. Once through the opening, immediately turn to your left and the datacron containing the Red Matrix Shard can be found at the bottom of a small pit in the ground.
