This is banned by order of the QM. The physics does not allow for it to happen.
All the easier for us to sign a treaty banning attempts to do it, then!
We can also have clauses in the treaty banning square circles and burning ice cubes.
I was tempted to throw in "honest used car salesmen," but Humanity 2.0, God help us, probably has those. Also "reasonable Shiplords," but while that's starting to sound like an oxymoron, it's an oxymoron we want to oxygenate as hard as possible...
But your problem here is quite simple: how do you make it stick? The Shiplords spent a long time trying to answer that question. Look where it got them.
Well yes, but the point is that openly and solemnly avowing that we
absolutely will not blow up the galaxy during this conflict hopefully scores us at least a FEW propaganda points as part of the overall effort to undermine the Shiplords and sow dissension within their ranks.
It gives more ammunition to the Hearthguard if they are even trying to argue "look, these guys are a hell of a lot more like the Teel than they are like the Gysians, and we really,
really shouldn't be trying to murder them for the sin of not wanting to all be murdered by us."
Do you want us to acknowledge that the Shiplords were fine for millions of years before something tripped over their tragic flaws, or not?
This.
@Snowfire , I'm going to be candid with you. This setting of yours has a terrible beauty and grandeur to it, and I
know you've spent years of your life building it up to the revelations we've had lately.
But you do need to allow for the fact that others won't necessarily see everything here the same way you do.
The Shiplords don't come across as relatable or sympathetic. They're
broken, they're horribly broken, and the monstrous crimes they have committed as a direct consequence of their brokenness are to a large extent responsible for their own total inability to find a permanent solution to the very problems they claim to be trying to solve by committing the crimes.
The Shiplords have dumped too much abuse on the galaxy for us as OOC quest voters, or realistically for the peoples of the galaxy itself IC, to embrace them and say "we understand that you were trying your best."
No, they were
not trying their best, or if they
were trying their best then their best is
shit. If this is the best they could do, then they should have responded to the Fourth Sorrow by totally abdicating their positions as galactic overlords, recusing themselves due to rank incompetence and unworthiness. And then they could pass that burden of duty, along with all their lore and equipment, on to the Teel. Who might not have been perfect at it, but would at least have not spent
the whole goddamn Pleistocene being complete monsters to everyone else in the galaxy.
That's the reality of the setting you've crafted. I'm sorry if that doesn't align with your own feelings on the matter, but it's what dozens of us see when we look at it from an outside view.
...
The point being, we do understand that the Shiplords themselves are in massive denial and are horrifyingly psychologically invested in continuing to murder everyone like they've been doing
for the entire Pleistocene and continue to do today. We understand roughly how they came to be in that kind of denial, and what justifications they use for their ongoing genocidal actions. We get it.
But at this point, we are basically sizing up their whole culture like a bunch of engineers sizing up a skyscraper to figure out where to put the big blocks of C4 to do a controlled demolition on it.
Which means we're not going to have a very romanticized view of it, and we're not going to have a lot of respect for the long list of reasons they've constructed for why the whole screaming blood-spattered murder-edifice doesn't need to come crashing down.
They did it by hiding the matter until they knew a race well enough to tell them. A galactic ban means that it's clearly stated to everyone that it is possible. Two very different mechanisms here.
All right, then. We phrase a very nonspecific and broad ban against "weapons of interstellar destruction" or whatever, perhaps "weapons of interstellar destruction using the Secrets." Basically anything bigger and hairier than whatever the hell War Fleets use to blow up stars.
It really shouldn't surprise or outrage the Shiplords that any species is
capable of thinking of means to use the Secrets for interstellar destruction. And if it does, we're already going to push that outrage button anyway when it turns out that G7 members (us) have been to the Sorrows, because you don't have to spend much time at the Sorrows to learn the basics about how the Secrets can be used to imperil the universe.
