Temple of the Ancients
The Temple of the Ancients, sometimes referred to as the Temple of the Elders, was a temple on Lehon that held the secrets of the Star Forge and, later, information about the supposed true way of the Sith as told by the Dark Lord Revan. Though the information was contained within the structure, the doors to the temple were blocked by a mysterious field of energy that could only be opened by Rakatan Elders, the descendants of the priest caste of the Infinite Empire.
Only three people used the ways of the Elders to make their way into the temple. The first was Revan, who had promised the Elders he would destroy the Star Forge but ended up using it for himself. Revan also left a holocron in the temple with his beliefs on the way of the Sith. After Revan lost his memory, he sided with the Elders once again and fulfilled his promise to destroy the Star Forge. The second person was Carden Mannux. Carden brought the infant Damien Starkiller to Lehon where he would be safe and also used the time to finish his manifesto with instructions on how to form the Dark Guardians of Lettow. Both Carden and Ussej Padric Bac III were killed just outside the temple. The third and final person was Darth Bane who found the holocron of Revan and used it to institute his famed Rule of Two.
The temple itself was over twenty meters tall with a summit located on the highest level. It also contained an elevator to the main floor, as well as a disruptor field that forced starships to land on the planet, though sometimes they crashed landed as they did not know what to expect from the mysterious disruptor field. The only people to escape the field were Revan, Malak, the crew of the Ebon Hawk, Carden Mannux and Darth Bane.
