"I've been waiting for you, Obi-Wan," Vader said as he stepped even closer.  "We meet again, at last.  The circle is now complete."
	Obi-Wan angled his lightsaber to assume an offensive position.
	Vader continued, "When I left you, I was but the learner; now I am the master."
	"Only a aster of evil, Darth," Obi-Wan said.  He used Vader's Sith Lord title mockingly, as if he were addressing an unfortunately named child.  He had hoped the insult might catch Vader off guard, and followed with a sudden lunge, but Vader easily blocked it with his own weapon.  There was a loud electric crackly as the blades made contact.
	Obi-Wan swung again and again, and Vader parried each strike.
	Vader said, "You powers are weak, old man,"
	Although Obi-Wan could only imagine what was left of Vader's features behind the black mask, he somehow suspected that Vader was smiling.  "You can't win, Darth," Obi-Wan said.  "If you strike me down, I shall become more powerful than you can possibly imagine."
	"You should not have come back."
	Their lightsabers clashed again and again.  And as their battle continued, they moved closer to the main doorway that led directly to the Millennium Falcon's hangar.
	Obi-Was risked a glance through the hangar's open doorway and saw four stormtroopers guarding the Falcon.  HE also sensed Luke was nearby.  Hoping to cause a distraction that would allow Luke to board the Falcon, he attacked Vader more vigorously.  The noise of clashing lightsabers echoed into the hangar, attracting the stormtroopers' attention.
	with his peripheral vision, Obi-Wan saw the stormtroopers, leave their stations beside the Falcon and run toward him and Vader.  He continued his attack on Vader, and several exchanges later, he sensed Luke's movement and knew his plan had worked.  He risked another glance into the hangar to see several figures racing for the Falcon's landing ramp: the droids, Chewbacca, Han Solo, and--Leia!
	Obi-Wan hadn't known that Princess Leia was on the battle station, but he recognized the girl in the white dress from the hologram that R2-D2 had displayed.  Obi-Wan did not believe in luck or coincidences, and seeing Luke unwittingly reunited with his twin sister, he knew that it was not a tractor beam that had brought him to the battle station, but the will of the Force.
	His fleeting glance also registered that Luke had paused behind his friends.  Luke stood a short distance from the landing ramp and was staring straight at him, gaping.
	Obi-Wan realized there was only one way Luke, Leia, and the others would escape the battle station alive.  He smiled as he looked away from Luke, then closed his eyes and raised his lightsaber up before him.
	Darth Vader did not hesitate to strike.
