Primary Transportation Authority near Persephone -- I think this might be the "on" switch once we fix the building mistake in Sol with the Talmor LensI'm interested to know, what the 'highly suspect installations' are in Sol? Old lurker re-lurking so might have missed some important information...
Chamberlain Foundation -- seem to be related to guy who ran NASA's Lunar Science Institute (see https://history.aip.org/phn/11503003.html) - maybe this is the access to the Moon. If you look at the lore, there is a consistent emphasis on mother goddesses. These are often symbolized by the Moon.
Delphi Control Chapter -- perhaps AEGIS has more reason to be Sol that we've been told. Look up "Delphi" on INARA. There is network of these damn things and I don't think that is a coincidence, either.
Conjoint Mathemathics Services .. possibly the beginning of the trail.
The other big question is have the game mechanics for triggering it evolved as the game evolved. That is not something I can say I know but I am going to start plugging away at possible triggers to see if we can open new doors. The Moon is important. I think it is being held off as a reward for figuring this whole thing out. Also, I'd love to know how and why Triton fits into all this.
