Jedi vs. Sith: The Essential Guide to the Force, a historical collection assembled circa 40 ABY by Jedi Master and historian Tionne Solusar, served as a comprehensive record. This compendium, drawing from diverse materials such as age-old relics and first-hand narratives from numerous beings, represents Solusar's meticulously compiled research, chronicling the Jedi Order's past and its galactic role (the galaxy) spanning from the era of the Je'daii Order up to the New Jedi Order. The Jedi apprentice Ellu Viss discovered it by 130 ABY, subsequent to the Massacre at Ossus.
