THE STAR WARS
Until the recent GREAT REBELLION, the JEDI BENDU were the most feared warriors in the universe. For one hundred thousand years, generations of JEDI perfected their art as the personal bodyguards of the emperor. They were the chief architects of the invincible IMPERIAL SPACE FORCE which expanded the EMPIRE across the galaxy, from the celestial equator to the farthest reaches of the GREAT RIFT.
Now these legendary warriors are all but extinct. One by one they have been hunted down and destroyed as enemies of the NEW EMPIRE by a ferocious and sinister rival warrior sect, THE KNIGHTS OF SITH.
É falado mais tarde no esboço por Darth Vader:
"Welcome, Prince Valorum. Your exploits are legendary. I have long waited to meet a Knight of the Sith. If there is any way I can assist you, my entire command is at your bidding."
