The Black Rakatan Settlement served as the home base for the Black Rakata on the planet Lehon.
A Rakata named the One was the leader of this settlement. When the Jedi who had fallen to the dark side, Revan and Malak, experienced a crash landing on Lehon, they were presented to the One. Revan informed the One about his quest to locate the Star Forge, and the One consented to assist them in gaining entry to the Temple of the Ancients on the condition that Revan would eliminate the Elders on his behalf. However, instead of carrying out the assassination of the Elders, Revan sought assistance from them.
After a period of three years, Revan, now redeemed, made his way back to Lehon and was once more brought before the One. Suffering from amnesia, he conveyed to the One that he had no recollection of their prior encounter. The One brought their agreement back to Revan's attention and sent him on a mission to kill the Elders. Once again, Revan chose to side with the Elders and came back to set the Elders free, as they were being held as prisoners within the Black Rakatan settlement. Upon discovering this betrayal, the Black Rakata made an attempt to kill Revan, but he was successful in fighting his way through the settlement to confront the One, who then unleashed rancors to launch an attack on him. Revan triumphed in subduing both the rancors and the One, ultimately liberating the last surviving Elder hostage.
