Jedi

A Jedi was a member of the Jedi Order, who studied, served and used the mystical energies of the Force—usually, the light side of the Force. The weapon of the Jedi was the lightsaber, a weapon with a blade made of pure energy. The Jedi fought for peace and justice in the Galactic Republic, usually against their mortal enemies, the Sith and Dark Jedi, who followed the dark side of the Force. Although the Order was almost destroyed four times, including once by the Sith Empire of Darth Revan, by the Sith Triumvirate under Darth Nihilus during the First Jedi Purge shortly after, 4,000 years after that by the Great Jedi Purge of Darth Sidious, and a century and a half afterwards by Darth Krayt's Galactic Empire and its Third Jedi Purge, the order continued to live on, in part due to the Skywalker family who time and time again played important parts in the history of the Jedi.
