I've been thinking about the Final Story encounter - the Sol Progeny. Why are they called the Sol Progeny - Children of Sol? Why are the ruins on Venus so "black garden-esque"? Imminent, Eschaton, Primeval. The Sol Progeny clearly is named for its dominion over all time. The Black Garden supposedly exists outside of space and time, so the Sol Progeny shouldn't directly link back to our solar system in the way that it does. This seems to be a telling sign that the Vex somehow originated here, in this solar system. The ghost fragment from venus states that the traveler is bringing a 'rebirth' to venus - clearly there was civilization there before. or after, or now. This idea of time as a cycle seems fantastic to me, because one of the themes of Destiny is 'survival'. How better to survive and ensure continued existence than to write yourself into the very laws of the universe, or turn time into a feedback loop whereupon you are just continually improving and each time cycle becomes a "revision". Anyway, The vex chassis appear to be made of copper or bronze - This could possibly be a Vex artifact. Perhaps including models of the planets that they have 'networked', are 'networking', and will 'network' Then there's the quote in the exo card: "Why were the exo minds created so similar to humans? I think somebody wanted to live forever..." Do we know that the exo weren't created by the Warminds?
