Jedi Order

"First comes the day
Then comes the night. After the darkness Shines through the light. The difference, they say, Is only made right By the resolving of gray Through refined Jedi sight."

The Jedi Order was an ancient, monastic peacekeeping organization united in their observance of the Force, specifically the light side. A noble order of protectors noted for their lightsabers and ability to tap into the power of the Force, the Jedi served as guardians of peace and justice in the Galactic Republic for over a thousand generations. Like the Republic, the Order was headquartered on Coruscant—the political center of the galaxy—where thousands of Jedi Knights studied, trained and lived within the walls of the Jedi Temple, which additionally housed the Jedi Archives and by extension the Order's accumulated knowledge. The Jedi High Council, the highest governing body of the Order, consisted of twelve Jedi Masters including the Grand Master and the Master of the Order. The training of Jedi was one of the most important traditions in the history of the Order, with Padawans learning the ways of the Force and the Jedi Code from the more experienced Jedi who held the rank of Knight or Master.
Over the millennia, the Jedi fought against the Sith—another ancient monastic order, but one whose members harnessed the power of the dark side—until the latter was all but destroyed due to internal fighting approximately one thousand years before the Invasion of Naboo. Unknown to the Jedi at the time, the Sith fragments survived and have been seen and eradicated across the galaxy.
