There is some mention of a 'dyson sphere' and leaving new eden to escape the Jovians, but that's all.
Correction (and apologies for vagueness; was up all night with my kids who were refusing to sleep, after 3 days of insomnia; all work and no sleep make Homer something something...
), it was where the Amarr scientist enters the Sleeper structures. At the very beginning of that chapter. Give me a few hours to wake up and I can find the exact page if necessary.
Torfi doesn't explain much more than is in there; that the locus IDs correspond to quasars, and what Quasars are (and sort of why they're important). What he doesn't mention, and what is only in Templar One, is that they're the nearest common identifying navigation markers to both New Eden and W-space. He hints at this, but yeah, I think he was just setting the stage for what was coming with exploration (and showing how big--how really, amazingly big that you have no idea--the universe is).
Meaning W-space is really, really far away.
There's some other hints in the presentation that might be missed, and I might honestly be imagining them, but that's the general importance of the locus ID info. It's not a big reveal, just setting the stage.
Oh, and
I want to leave my ship and go all Indiana Jones on some Sleeper drones!
