Xendor's manifesto was a written collection of the teachings of Xendor, the first Dark Jedi and the instigator of the First Jedi Schism in the centuries following the formation of the Galactic Republic. Following Xendor's death at the end of the schism, the survivors of his Legions of Lettow placed the manifesto on the planet Conscio, where it was forgotten until it was found by the Ospion Guardians in 12,999 BBY. The Ospion Guardians began to follow these teachings and renamed themselves the Dark Jedi of the Bogan.
