A good point has been made here though. We do know that at least some ancients were in GTVA space before they moved out through Gamma Draconis
Now that you said that, a new theory hit me. Maybe they moved IN through Gamma Drac? (perhaps they had discovered the system long ago, but never colonized? Built the Knossos to sustain the node even if it should one day collapse..?) Perhaps they were fleeing the Shivans out through Gamma Drac, set up some quiet colonies in the Altair/Deneb area hoping that they had evaded detection, encountering the Vasudans along the way?
That would seem to make sense judging by the severe lack of Ancients technology floating around GTVA systems, and the small numbers of ruins would be consistent with new colonies rather then established words. Also, you'd think there'd be Shivan wreckage floating around during the T-V war if the GTVA had been around established ancient worlds, but the GTA and PVE find ZERO evidence of the Shivans during the 14 year war, and as of yet, still haven't found any. I'm wondering if that's maybe because the Lucifer Fleet found the ancients little colonies, wiped them out, and then continued roaming the galaxy looking for more escaped ancients?
That would help to explain why there were no evidence of Shivans in GTVA space - they never had to fight sustained campaigns there. And then the Lucifer Fleet maybe cycled back around, discovering the Terrans and Vasudans?
I have a weird memory of someone from
saying that they had considered including the ancients as a playable race in the third if they had actually made it, am I right or just completely and totally out to lunch? If so, that might be consistent with the ancients having far flung 'evacuee' colonies
