When they finally managed to get their captors to understand what they were saying, they didn't know what Revan was looking for and told him to ask the other tribe. After Revan and Malak found the camp and listened to the concerns of the Elder tribe they discovered how the Rakata had lost their use of the Force. Revan also learnt that the Rakata had built the Star Forge. Revan lied to them calling himself a Jedi and the natives then told him how enter the Temple of the Ancients but that he and Malak were not free to go until they had helped the Rakata restore their use of the Force.
The Rakata continued their civil war and Lehon was unknown to Republic once more during the rest of the Jedi Civil War until the concluding battle of the war.
