Re: VAULTS | Their real purpose. Your thoughts?
I've always viewed this from a simplistic perspective. The Jardaan created the Angara and created the technology we call Remnant to make life sustainable for them in this galaxy. Experiment or some grand design, I don't know. But someone didn't like it, hence the Scourge. Might be a bit far fetched, but the fact that MA:E introduces the idea of the Kett's exaltation shows a direct contrast to the creation of the Jardaan. I believe there is a reason that contrast was introduced, but there isn't enough info yet to really know why.
Edit: And as to the human-friendly vaults, I think that was just coincidence. The Angaran are the only ones whose "fruit" we scan and find edible. I think the devs were trying to show that there are similarities to us strictly for this reason.
