That's not all what I interpret. I see this as Eärwa literally being special,
agreed. I'm not arguing that Earwa isn't special, but that they likely thought every one was special - else why bother exterminating them.
which is also probably the reason why Ark crashed.
Could be. No issues there.
Something about this world sets it apart from the rest of the universe.
Right, that's pretty obvious.
They used the No-God on other worlds,
No idea how you got to that conclusion.
but were unable to shut off the Outside.
Right.
Also, take Bakkers comment about the No-God and e.g. Kelmomas:
"And lastly, it's not the blood that enables the Carapace, its the ability of the brain to functionally emulate that of an original Insertant."
Did he say original "insertant"? I thought he said original creators. Doesn't matter though:
How would there be an original Insertant if Ark didn't know about the No-God? It was an extension of itself, as the Mutilated also mention.
You answered your own question. The Ark
is the No-God, but something something Earwa short circuited it. The Ark was the original insertant, in that, the Ark was basically the original no-god. The Sarcophagus is a stripped down version that can move around without using all the power of several suns. ... In essence, we're both right?
The No-God needed something to approximate the Ark brain so it could move around without the ark directing it ... directly. My present guess is that the ark via neuropuncture took a brain that was close enough, did some rewiring to approximate itself, and sent its baby out into the word to kill all humans.
I maintain that the Inchoroi didn't know anything of the No-God. They're a dumb weapon race with little idea of what the Ark was doing or wanted. Shae and the Consult created the No-God as we know it. Shae being a big key here, as he was smarter than all the living inchoroi, and apparently smarter than most any man in history save the dunyain. I assume given that the original NG had the chorae, that it was a tekne creation.
At any rate, imo the inoculation was a bioweapon the inchoroi made with the tekne.
The womb plague was something different related to the rise of the no-god.
