Darth Bane började innan Sith var så hemlighetsfull, han var en ledande medlem av Darkness Brotherhood som kämpade öppet för Jedi. Boken Jedi-sökvägen , en guide till Jedi-ordningen, som förmodligen skrevs av några Jedi om ett decennium efter New Sith Wars och läs av Yoda (vars anteckningar visas i boken tillsammans med andra Jedi) har en sektion på Darth Ban på p. 148 som innehåller en bild, så det verkar inte som att hans utseende var en hemlighet. Boken visar att Jedi trodde att han hade dött i striden på Ruusan och sade:
In the war's last decade, Bane rose through the ranks of the Brotherhood of Darkness to challenge the leadership of Sith Lord Kaan. From the Sith prisoners in custody on Akrit'tar, we have learned that many of them considered Bane to be the Sith'ari—the culmination of a prophecy that foretold the rise of a perfect being. This divination, an inverted mirror of the Jedi prophecy of the Chosen One, reflected the Sith need to cast their hopes upon a savior as the Jedi Army of Light closed in on them. Bane's popularity split the ranks of the Sith Lords, causing them to lose focus and to surrender key ground at Ruusan. Ultimately, Lord Kaan knew he could not win and triggered a Thought Bomb. This unspeakable dark side weapon scorched the surface of Ruusan and drew the spirits of every combatant, Jedi and Sith, into its bottomless singularity.
Bane died with the rest of the Sith Lords on Ruusan, proving that not even the Sith'ari could sustain an order founded on aggression and greed.
