It was stored in the Jedi Temple on Coruscant until the Great Galactic War. During the Sacking of Coruscant, the temple was destroyed; this led to the Noetikons becoming lost. The Noetikon fell into the hands of Gand scavengers by the time of the Cold War. At this time, a mysterious Force related sickness had infected Master Yuon Par and an unidentified Jedi Consular went on a quest to recover the Noetikons to find a cure.
This Jedi managed to consult with the Noetikon of Science with its three Jedi Masters going through their storehouse of knowledge. However, they were unable to identify the illness or provide a cure. Instead, they suggested that the Consular seek the Noetikon of Light for a possible answer.
