While I do quite like Alratans bonesinger weapon/armor foundry plan the lack of Scrying options related to Nacretinei really hurts it in my opinion.
As I say, I think it's too dangerous. As we're the people who revealed his curse, I think Kairos is likely to hate us, and be particularly spiteful.
He still has a tap into our Scrying, and so if we scry Nacretinei I think that will tell him that we particularly care about them, which, because of that spite, will make him particularly care about screwing with them.
As the Webway is currently breached and has daemons running around in it, Kairos may well be in a position to do so.
That's why I'm avoiding doing so. While it might help, it might also significantly hurt.
In order to look for Nacretinei, we have to coordinate with their allies anyway, and as part of that we can learn what the results of their scrying is, or ask them to do more, as Kairos probably isn't particularly watching what they Scry for opportunities to dick with them like he may be with us. I think that means we will still have Scrying support, but it's much safer if we rely on someone else doing it.
We're not looking for Nacretinei solo, so I don't think we need to do everything ourselves. See here:
Re: Nacretinei; Their friends are absolutely looking with what they can afford to spare already, this turn, because temporary interruptions in communication between Craftworlds is pretty normal at the moment but missing something like the Aeldmoot after stating one's intentions to go is another matter entirely. Throwing in your own two cents to the effort in a reasonable manner would require a degree of actual coordination, yes, though you can certainly earmark fleet and warhost assets for the physical searching portion in advance if you so desire, which would give you a modest head start on that front. (ordinarily I would follow this with warnings about then not having them, but as you are explicitly in something of a lul period thanks to some very favorable rolls and your specific focuses over the first three turns having cleared out most of the immediate issues more quickly than anticipated, that doesn't really apply.)
I like that this plan gets started on foundries for T2 gear. I would like to start chipping away at engines (I saw all the reasons why and why not and this is my final preference), but I value the thing above more.
If I will be able to, I will advocate for doing the thing left from winning plan next turn.
If my plan wins, I'd hope to build enough more BAP that we can throw down eight BAP all at once one turn soon to finish the Engine Controls in one go, so we don't have them hanging around part done, so we can then start the Stewardship project to man the controls.
