The Massassi, who were once enslaved by the Sith, built the Great Temple of Massassi in the jungles of Yavin 4 five thousand years before the Battle of Yavin. By the time of the Galactic Civil War, the Massassi race was extinct.
After their extinction, the Massassi were mentioned in a travel advertisement written by a Special Galaxy Reporter who had investigated the Great Temple ruins after the Alliance to Restore the Republic abandoned the jungle moon.
