The timing of their discovery is relevant. There are parts of those subsectors that are nearly impossible for the J1 Vilani to get to (never mind the three+ year travel time each way), so despite the round numbers given in GTIW (4000 years before the IW) they may have been contacted early in the Consolidation Wars period as the Vilani explored the Geonee backfield instead of two thousand years prior to that in the J1 period. If they are a J1 period contact, that tends to eliminate most of Subsector A due to needing a lot of gulf hopping with no logistics tail.
Yes, there are inconsistencies in the writing. One thing to remember for the elements involved is when they were written. The DGP map is 1990, Path of Tears is mid '90s, GTIW is 2006. Perhaps the dating in GTIW is wrong. Perhaps the DGP dotmap inaccurate. TNE might be wrong because of Anakundu had not been written about yet.
Well that is part of Stone Soup. The process of eliminating the undesired ingredients to get the best soup, er, find the homeworld of the Anakundu.
All boiling down to "What does the Third Imperium find there when they return?" Savages? Empty ruins? A thriving Vilani-favoring pocket?
Well to address that point, we work with what makes most soup, er...sense. As part of the elimination process for example, I took the dotmap, "facts" about the Anakundu (racial environmental data from GTIW, and now your suggestion with Path of Tears. I eliminated planets which have people in subsectors I and J, keeping boneyards and eliminating inhabited worlds. TNE RC and Path of Tears is not changed with an Anakundu boneyard. The dotmap is not inaccurate. Hmm two out of three
IF and I say IF the Anakundu homeworld was in the RC, then it might have been on Slandow (Old Expanses 1126 C9D4685-8) as it meets the elimination process. It is in the area of the dotmap, it meets environmental (I forgot I to mention I kept atmospheres D and E), and they are a boneyard by TNE times.
Now I will take into account your suggestion of the J1/J2 issue. That also reminds me to review 1248 and see if there is anything to glean there.
