I interpret that as "the Core behind the conduit in NGC 224 is far more important and central than the two Control Centers in the Milky Way".
It is not. The backlash from the Blade's actions on the other side of the exogalactic wormhole blows up the planets on our side of it, which is why the AI shuts down. Destroying the Core in isolation DOES damage the AI, but not the same way.
Are you making that up as you go?
Nah, seriously, I don't fully understand that part of your explanation. My understanding was simple: "Exile cross wormhole and kill Core". But then you speak about backslash from the other side of the wormhole that destroys the AI.
"Destroying the Core in isolation DOES damage the AI, but not the same way." Is that sentence grammatically correct? I'm sure not an expert in English, but I genuinely don't understand that.
As an aside: we're approaching the setting and story in two opposite ways. You're focusing on the characters and what they specifically did, ie the Great Man theory of history. I reject that. It's the societies and the forces they bring to bear that matter. Langstrom, Artain, the Exiles and the rest are accessories to how human civilization chose to automate the engines of war until said engines took the choices away from them. This would have happened without them.
That's Asimov's vision as developed in the Foundation series. Very well, I take that.
So the AI around the Core is... But first, let's clearly define things. I call "The Core" the Spire being that was banished (alongside with its sibling). Langstrom and Artain... Well, okay,
Human scientists gave to the Core their fleet control technology to use it as a tactician in the civil war. They called it AI. (So I call AI that Core empowered with Human technology.) Then that new AI tricked
Artain Human scientist into removing securities that restrained it. The AI/Core then built servants, nearly eradicated mankind, escaped through the conduit and attacked the Spire Empire to get revenge.
And you are saying that this AI/Core/Exiled isn't the cause of everything?
Okay, I'll make an effort. So it's more Human technology that turned against them? But why? Because the Core/Exile tricked them into removing the securities! Ah, okay, I said I'll make an effort. So the Core, twisted by Human technology, attacked mankind... because Frankenstein. Mankind creates it's own demise. Because that's the beginning and the end of the loop: AI War 1.0 begun as "mankind will destroy itself" and must ends with "mankind destroys itself". And that is highly reproved by Asimov (and me, by the way).
No, I'm sorry. Your explanation is more complex than mine, and I dislike the philosophy behind it. You might be Arcen's Lore Voice, but I don't buy it.
The Core is behind the Conduits in NGC 224 and the two "AIs" in the Milky Way are servants. That's simple, clear and coherent with the game. Anything else would be either complex or incoherent.
I'm sorry, I'm tired and I shouldn't be writing that so late. But I have a clear and coherent vision of that and you offer me an explanation that I don't understand. I say "that I don't understand": this is my point of view, right now, minutes after midnight. Maybe tomorrow I'll understand better. Maybe if you would explain me again the ins and outs of that, I'll understand better too. I would appreciate, anyway.
Thank you for your time and your patience.
