I kept wondering if the Remnant vaults were deactivated due to a horrible, unforeseen side effect

Are there any even remotely habitable non-Remnant planets in the cluster? I don't recall coming across any, but I didn't read the planet descriptions while exploring/scanning very closely either.

I agree it's foolish to rely on technology they don't understand, but they don't have any choice at this point. Hopefully SAM will be able to help Peebee and the other scientists figure things out. Meridian still seems like a terrible idea. I think that's seriously going to bite them in the bum somehow.

Edit: Also, wasn't the Scourge created by an opposing faction/enemy of the people who created the Remnant?

It's definitely a plot line they left open, one that I hope we get to see more of in MEA2.  (Yeah, I'm one of the 'delusional fans' who thinks there will be a second.  No apologies.)   

Living on planets controlled by these vaults that could malfunction at any time with a main kill switch somewhere else is nerve wrecking as a civilian on those planets..

..the scourge is attracted to the remnant and I'm sure it would spread to those planets sooner or later.

It sounded like they turned off the lights, packed the car and went into hiding, sending Meridian away so it couldn't be used while they were gone.

Hmm, this is interesting. I had not considered this.

Question: did the Jaardan specifically say what the "weapon" was that was unleashed on them by their enemy? It's alot of bits of info, so I may have missed some. But now that I'm wondering, what I remember was them referring just to a weapon, not necessarily the Scourge, or description of it because I doubt they called it the Scourge.

I also remember at the end finding out that the Jaardan were-for some reason-wary of Meridian itself, even though they tucked it away.

Could it be that these vaults and whatnot were hacked by their enemy and then used like a Trojan Horse, and the Scourge was actually deployed by the Jaardan to wipe the system? And a hard reboot/wipe of a system can really jank your stuff up. All the software and upgrades, everything you've done to that point - janked up.

Then Meridian being something like the super hard drive core of the system needed to saved, but they weren't entirely sure if it was "virus" free. Maybe the Jaardan in creating this tech and vaults left a back door wide open?

Although, do we know for sure that the Jaardan created the remnant tech? I doubt the Angaran know for sure, either. I mean, but do we know, or am I just filling in the spaces of missing info with assumption? Or did the Jaardan stumble upon it, too. Only to find it was a trap?

oh, god.
