Again, it isn't consistent with what we see in game seeing as some of Ram Tah's translation's contradict themselves. There's a massive what if with the exiles. Also, yet again, he's hardly going to drop a massive spoiler by saying "Yeah, these guys you think are extinct aren't".
We simply cannot say for certain in game, and that's the crux of the matter.
Ok, I take your point, but equally, how much can we say for certain in-game?
Galnet isn't a source of certainty, it's a source of PF approved info. Other sources of info in-game have changed. Sources are all dubious.
And with the Guardian stuff, I'm most definitely not saying what's in game is consistent, as it certainly doesn't appear to be - Melville and Ram Tah certainly seem to contradict each other.
I'm not sure there's that much contradiction within Ram Tah's info though. Sure if you treat every set of the data as independent and parallel, then yeah, there's contradiction, but equally they're not independent and parallel.
Regardless of the few discrepancies, is there actually anything that contradicts what DB said?
The exiles stuff is all consistent with what DB said, unless you take the view that the rapidly increasing development they had already started experiencing stopped completely post-exile and they didn't change over a million years or two. And wouldn't that view be much more far fetched than what DB said being correct?
And yeah, I don't think DB would drop a massive spoiler like that - but I think he would say something that's technically correct but leaves open a variety of possibilities, which is what I think he's done.
