A Little Knowledge
Overseer Harkun has issued your third trial. You are to travel to the wilds of Korriban and enter the tomb of Marka Ragons. There, you need to retrieve an ancient holocron that no Sith has been able to retrieve for a thousand years.
Your task now is to speak to the shuttle droid outside of the Academy and take a taxi to the lower wilds. Exit the Academy and talk to the Sith Academy Skyhopper. Click to travel to Lower Wilds. Make sure to bind there so that you can quick travel in the future. Then take the road leading south. When you reach Wilds Laboratory, turn north. Keep going all the way north until you reach the tomb, and enter it. Inside the tomb, defeat 5 Acolyte Deserters to complete bonus mission "Reward Failure Accordingly". Then enter the Monument Chamber. Inside the chamber kill 4 Shyrack Screechers for the bonus mission "Silence the Screechers".
Your task is to retrieve the Ancient Holocron. Climb the platform and interact with the great stone monument on the top of the pyramid. The holocron's monument bears the marks of many hundreds of unsuccessful attempts to pr it open. You can: Recite the Sith Code, Break it, or Meditate on the dark side. Try Meditating on the dark side. The monument shudders, and beasts rush in and attack. Defeat the beasts, then interact with the monument again. Try offering blood to it but the monument remains unopened. Shoot lightning at it. The monument shudders and then opens, revealing the holocron. Your goal now is to bring the holocron to Overseer Harkun in his chambers in the Sith Academy and report your achievement. Quick Travel back, if possible, then report to Overseer Harkun.
Harkun cannot believe you really managed to retrieve the Holocron and accuses you of bringing a fake. He tells you he will deal with you later. As a demonstration, he has Ffon Althe kill Gerr. He then gives you your next trial. The last, darkest secrets of Tula Hord are buried in his tomb. Lord Zash wants his text. But the final resting place of the dead lord is not easily trespassed. You will not be the first to die there. He tells you not to come back here until you have gotten the text from Tulak Hord's tomb.
This ends the quest "A Little Knowledge" and starts the next mission, "The Secret of Tulak Hord".
