We still don't know how big the ancients space is on the GD side exactly. Were not sure if it even joins up with Shivan space by normal routes, otherwise why would the shivans wait for us to open GD, why not send another fleet.
The lucifers movements after they ran into the terrans again was not to get back to GD, but was to wipe them out. They did head straight to the Vasudan homeworld as if they already knew where to strike.
They were just heading back that way initially until they ran into em.
Yeah it seems abit weird that the first lucifer wasn't killed but something had to disable that node so I'm assuming that was it. Maybe the first lucifer had already penetrated too far into their space, and the attack on the 2nd one was just an attack of oppertunity, like payback lol?
If the Ancients could have continued to explore space through normal subspace nodes I believe they wouldn't have bothered with Knosses devices cause there would have been no need.
Yup all this is just theory and stuff, plus I havn't played FS2 in 5 years so I need to "catch up" on it's story line but I remember most of it heh.
In FS1 the Ancients talk about how they have exploited all their reachable systems which I believe is every system they managed to get to before they created knosses. They created knosses cause they had no where else to go.
Maybe the lucifer was just patroling that side of space and has gone past terra and vasudan tones of times in the past 8000 years, but they hadn't been a threat until they trespased into space.
The shivans only care about Space, they consider it theirs, they don't care what happens on the planets until those planets harbour life that has trespased.
As for capella, yeah I have to play FS2 again but that was a theory as I remember and probably my crappiest theory.
When the 2nd Shivan fleet attacked they could have assumed that their original fleet failed, and that the ancients still existed. Probably why they went to such an extreme in capella, and I believe 80 sanths are nothing to the shivans
