OK. Now I am now looking for galactographical clues in other van Rijn stories, e.g.:
"'This star which its discoverers called Osman is out past Antares, on the far edge of present-day regular-basis League activities. One planet is inhabited, called by humans Suleiman. Subjovian; life based on hydrogen, ammonia, methane; primitive natives, but friendly.'"
-Poul Anderson, "Esau" IN Anderson, The Van Rijn Method (Riverdale, NY, December 2009), pp. 517-553 AT p. 522.
The information soon becomes planetary, not stellar. However, anyone who knows or can enquire where and at what distance Antares and similarly named stars are located gets a sense of the volume of space permeated by Polesotechnic League activities.
There is one more such datum in this story. Some species can use the Suleimanite plant, bluejack, as a spice and tonic and:
"'Best market for bluejack is on a planet we call Babur. Its star, Mogul, lies in the same general region, about thirty light-years from Osman.'"
-ibid., p. 523.
We usually skip past such details but for once I am focusing on them.
We find another parallel between two stories:
"Van Rijn wallowed deeper into his lounger..."
-ibid., p. 522.
"Nicholas van Rijn wallowed his bulk deeper into his lounger..."
-"The Master Key" (
here), p. 277.
But there is a difference. In "The Master Key," van Rijn remains recumbent and solves a problem with his little grey cells whereas, in "Esau," we are told that he avalanches to his feet at the prospect that the talented Emil Dalmady will seek employment elsewhere.
