Dark Lord Exar Kun once shattered a Sith holocron to release the ancient spirits trapped within, who would go on to possess the bodies of the assembled Jedi apprentices and send them to slay their former masters. It is possible that the technology of the mind trap was somehow related to that of the Holocrons employed by the Rakata for data storage the Builders attempted to win over the Sith ruler, King Adas, with the gift of holocron construction, and the ancient Sith were known to have subsequently discovered methods by which Sith spirits could be imprisoned inside the crystal matrix. It is unknown what he used it for or if the Rakatan prisoner ever escaped. Revan then went on to Tatooine as planned and gave it to Motta at the local swoop track. However the box worked, he was unable to activate it again. After stumping the warrior, Revan was given leave to escape back into his own body. After all that time, the warrior could not even remember his own name, but still desired to escape, and so challenged Revan to the only contest that would be fair to both and applicable in a world where neither had a physical body: a game of riddles. Revan met the prison's original occupant, a Rakatan warrior who had been imprisoned for leading a rebellion over 21,000 years ago. Two others had also become trapped there in the last month, but they had already gone mad and run off into the white void. Lurze did not say what would happen if he did, though, and Revan's curiosity overcame his caution, trapping him in the prison. He hired Revan to serve as courier, with one warning: never to open the box. Somehow, the Rodian Lurze Kesh acquired one of these prisons and sold it to Motta the Hutt. The whiteness would drive beings mad unless they weren't irritated by it Faint whispering could be heard, possibly the voices of others who had become trapped.

For prisoners inside, however, the prison took the form of an infinite expanse of white nothingness, with a small cluster of obelisks and a single bed in the middle. From the outside, it appeared to be simply a mysterious glowing box with runes carved along the side. The only means of escaping the prison was into the body of another who had inadvertently become trapped, although this required the consent of both involved. A prisoner's mind was stripped from his body and locked away within the prison, presumably forever. A Rakatan mind trap was an artifact built by the Rakatan species as a form of imprisonment for criminals who had committed particularly terrible crimes.
