One Of The Greatest Unsolved Mysteries In Mass Effect: Andromeda

Further strengthens my opinion that the game story could have been more interesting if we would have come during the war that the Jardaan fought.

I like for the next game, or maybe dlc, go into detail about them.

At the beginning, Ryder mentions that the structures could be several centuries old, but they would have shown up on the scans that was used for the Initiative. When going in Eos vault, the sam voice says radiation readings, or whatever it said, indicate the vault has been inactive for about 500 hundred years. So did the Jardaan build everything within 100 years? Very impressive if that's the case. Someone will correct me if I'm wrong.

The other things that have me interested is Jien Garson's death, the benfactor, what the kett will do and who created the scourge to use against the Jardaan.

Can't wait to see what future DLC will hold. Seems like we'll be getting one that revolves around the Quarian Ark, but I'm also hoping we get to learn more about the Scourge and Jardaan. I'd also completely be okay with a noir style investigation into Jien Garson's death and the Benefactor, for a whole DLC, similar to Lair of the Shadow Broker but with more scanning/investigating.

So, I'm at my 3rd playthrough (testing everything before defining my own personal game review), and I’ve to say I don’t see many other possible explanations on the role of the Jaardan as technocratic conquerors… save one.

As theory crafting goes, it has some weak points but I believe some strong points too: sadly, I don’t think the writers at Bioware are… gutsy enough to try this till its logic conclusion.

What if we got the correlation between scourge, habitats and vaults the other way around? Since the start of ME:A, we’re assuming that the vaults are meant to make planets habitable… but habitable for who? What if the Jardaan, just like the Rachni, are a species of extremophiles? What if they can only inhabit planets with extreme conditions, because they evolved in what are for us inhospitable ecosystems? They could need radiations to properly thrive, or oxygen could be harmful for them, and so warm climate: hell, it’s another galaxy. They could be protein based lifeforms for what we know, instead of DNA!
When the AI departed, the planets in the Heleus clusters were utterly viable… and in a sense, the vaults net worked out perfectly: the Jardaan, exactly like us, discovered a cluster of potentially habitable planets… which they had to terraform first though, in lieu of their different biology. And they did: what we perceive as the inhabitable conditions of Habitat 7, could have been perfectly fine for the Jardaan.
When we interface with planetary vaults in Andromeda, we don’t power them on again: we reset the “tuning” of the terraforming process to the planetary default (cue purification field as a defence against ill handling of the jardaan tech): the rest is only biased interpretation, based on our own biology. And imo, it would have more sense than the Scourge able to produce such different outcomes on the various ecosystems…
So, what we find in the Heleus cluster are perfectly viable planets… only for the Jardaan.

And what about the Scourge?
Should you see a race of inexplicable organisms bent to transform an entire cluster of planets in hellish wastelands, wouldn’t you try to make them stop by force?
“Hello, we’re the Jardaan, we like to make planets cold and/or radioactive…”
“Kill them with fire.”
The Scourge could be the results of a cultural misunderstanding, or the product of the struggle between very different biological imperatives.
The Angaran, with their biology able to shoulder almost any conditions (bar space vacuum) could have been the first try of the Jardaan to solve the problems tied to their particular biology. The Angaran could have been meant to be both the “representative” of the Jardaan to other species, and their “pathfinder” in hostile ecosystems (for the Jardaan of course).

***
The weak point of all the above, is that we should at least find hostile conditions in all the vaults and Meridian too, to be believable as a whole (at least more or less). Voeld vault seems to endorse this, not so all the others…
Even if the Vaults are high tech labs of the Jardaan, it seems strange to make them inhospitable to their own creators, after all. Still, we never explore one of them in its full extension, only parts of them: maybe there are “residential areas” for the Jardaan deployed there (assuming the vault were not meant to be self-sufficient from the start, with Meridian as the only supervising installation).
Also, Eladeen doesn’t support the above theory… but we could assume the vault there was built by the remnants on board the ship after it crashed, following their instructions: they don’t care they are on the wrong targeted planet, only the purpose instilled in them by the Jardaan.

Circumstantial evidences in favor of the above are that the Jardaan indeed used uranium and cancerous fungi to decorate the place on Meridian…

In the end, I don’t really know. Thoughts’ food, I suppose.

I think the Ark will be a DLC, but I agree, everything else is leading us to an actual sequel.

I also sort of compare the Jardaan to the elves in DA. They lost who they once were and only ruins remain hinting at the past they don't remember when the Veil went up.

We still don't know for sure whether The Jardaan refers to an actual species or a faction within the "remnant creator species". The term <Opposition> is so generic as to mean anything, from <racial enemy> to "folk who disagree with me". The Jardaan could be the Remnant-equivalent of scientologists...

There's that quest for the curator of Aya, to get the angaran relics. When you return the helmet to the curator you go into a very interesting conversation. So, you found an angaran helmet on an angaran ship. And the scourge hit the ship and also the pilot that was wearing the helmet, reaching the conclusion, the pilot was remnant but it was also angara (or at least wearing angaran gear). So maybe the remnant are the ancient angara, and the bodies they found on that city are just "spare parts" for them? Like jumping through bodies for longer longevity, or because of injuries sustained? Also the whole incarnation thing they talk so much about, its probably directly related with this body swapping thing.

I think I said a week or so again.

Angara = Elves.

Scourge = Red lyrium.

And Kett = Qunari

Yes I believe you are right. I just finished the Angaran AI quest on Voeld on my 2nd playthrough, and the AI kinda implies that the Angara of today are descendants from the original Angara, but so far off that she doesnt accept them as her masters. And if she is indeed an Original Angaran Creation, then they have nothing to do with the remnant, there are no remnant tech to be seen on that whole cave, and all her tech is very distinct from remnant tech. So, ye Jardaan might be a completely different race from the original Angara, and the current Angaran are quite different from their predecessors.

Still doesnt explain the Angaran bodies on the city. Maybe the Jardaan didnt create the Angara at all? Or maybe, to save the Angaran from extinction they made "copies" of them to ensure the species survived? Meh, still too many questions to know anything for sure But so far its been interesting to speculate, I just hope they can resolve all this misteries in a fulfilling way.
