Exar Kun: The Lesson, The Warning

Exar Kun: The Lesson, The Warning was a text written by members of the Jedi Order on the Jedi Knight Exar Kun's fall to the dark side of the Force. Written sometime after the end of the Great Sith War between Kun's Brotherhood of the Sith and the Galactic Republic in 3,996 BBY, the text was included in a list of suggested documents for Jedi Padawans to peruse during the Cold War between the Republic and the Sith Empire, three centuries after the war.
