Where are/were all the retirees from Galton? You know, the Alpha, Beta, Gamma Star Lines, not the (we would guess) lesser lines that may die really really early like normal humans?
If they are on the habitats (which did not self destruct) there would be all sorts of people who should KNOW SOMETHING about weapons development, logistic organization & operations, manufacturing. So how many hundreds of thousands of people with information are still alive- and not fitted with nanite assassins?
It is possible that the various false trails left behind with Galton will point to ALL of the spider drive and graser torpedo development and construction was supposedly on one or two of the major stations which did a very good job of self-destructing (timed simultaneous containment failure on multiple station fusion reactors would do nicely) and so NO specs or plans or physical copies of the ships/drives remain. BUT, where are the ships that hit Grayson and Manticore? Odd that they were not engaged at Galton.
So many loose ends for us as the readers. Like the other bits of the hidden wormhole network that Darius is part of.
And how likely is it that ALL of the Houdini people who went to Galton were only kept on stations that were either directly destroyed in the fighting or were self-destructed? No mention I can remember of what- if anything- happened to that off-limits enclave on the planet's surface, so what and who would still be there?
Too many questions for us. Too many, we are supposed to believe, for the GA as they sift though Galton's debris and surviving inhabitants.
