"Okay," Luke said, taking another deep breath. "It turned out that there was a reason the troopers were after Artoo and Threepio: Artoo had the complete schematics to the Death Star--a massive weapon--size of a small moon massive--that could blow up planets. Leia had put them into his memory and sent him off to find Obi-Wan Kenobi, the only Jedi Knight who was still alive, and that was a closely guarded secret."

He ran his free hand through his hair. "Ben--that's how I knew him--had been on Tatooine watching over me because he and my father had been best friends, though I never knew that because my uncle wouldn't let him within a klick of the farm. Artoo found him, Ben recognized Leia on the tape, the farm was destroyed anyway, so off we went to return the droid to the girl on the message."
