 Why was Retief's mission to Jorgensen's Worlds so important?
"It is rather unusual," Magnan said, "to assign an officer of your rank to courier duty, but this is an unusual mission." They're called Jorgensen's Worlds, and in themselves are of no importance whatever. Since they've met no opposition so far in their infiltration of Terrestrial space, they intend to seize Jorgensen's Worlds by force." Magnan leaned back, waiting for Retief's reaction. Retief drew carefully on his cigar and looked at Magnan. Unfortunately, Jorgensen's Worlds are technologically undeveloped areas. "I have here," he said solemnly, "information which will change that picture completely." "This is no occasion for flippancy, Retief. "If it's trapped for destruction, I suppose—" "I've heard of these Jorgensen's Worlds," Retief said. Overall policy calls for a defense of these backwater worlds. Otherwise the Corps would allow history to follow its natural course, as always." Retief opened the envelope Magnan handed him and looked at the tickets inside.

"For the two twenty-eight for Jorgensen's Worlds," Retief said. "But—" Retief picked up his suitcase and walked away toward the glare sign reading To Gates 16-30 . Retief followed the signs, threaded his way through crowds, found a covered ramp with the number 228 posted over it.
