Freedon Nadd was an Old Republic male Human Jedi prodigy whose conscious decision to embrace the dark side of the Force had a significant impact on galactic events for many generations after his death.

Federation-Sith War (195 ABY - 198 ABY)
During the time when the First Federation-Sith War started, a powerful sith cult, known as the Watchers, under the leadership of Mistress Qela Voolu, a female Falleen who studied a lot about Freedon Nadd, planned to bring the deceased sith back to the living and put an end to the New Jedi Order. On 190 ABY, Qela decided that she would like to resurrect Freedon Nadd and wanted to learn more about the secrets of the dark side of the force. They traveled to the ruins of the Tomb of Freedon Nadd and search for the remains of the sith lord's sarcophagus.
