"We're going to delay it as long as we can because outmaneuvering smarter Keltham's going to be even harder, maybe impossible. Officially, Acquisitions said it'll be two weeks and I went ahead and ordered one myself, which I can afford to do and you can't because I've been earning a generous salary from Cheliax for my work at the Worldwound for six years and you haven't. The gossip is that this is because, you know, some intelligence headbands are cursed, and even worse some are just a tiny bit cursed, make you see things in a particular light, and optimistically Acquisitions is making really sure the project headbands are good and pessimistically, well, they could be manufacturing them a little cursed. Please attempt to have a little bit of subtlety in causing this gossip to reach Keltham's ears. I actually suspect that only the 'optimistically' part needs to be said and he is competent to fill in the rest.
Also we are going to be hiding a lot behind you guys not actually being all that well-educated, not actually knowing that much history or politics or economics, because magical education in Cheliax is very specialized. The smarter you are the harder it is for you to make innocent mistakes.
Keltham is under the impression you were screened for willingness to bear his children; I think that's just true, but if it's not, you now explicitly have permission to lie about it. Keltham is under the impression you are getting generously paid; I think that's just true, because I have told everyone that we're doing as few lies as possible, but if it's not, you have permission to truthfully say 'I was told we would be generously paid and if the money isn't there I'm going to go to whoever's in charge here and make a nuisance of myself' and then to come to me, and maybe to lie after that depending what's up. Keltham is under the impression that if you didn't want to sleep with him, no one would make you; you have permission to lie to him about that, but also, if you find yourself getting cold feet in bed, you won't actually be punished for telling Keltham 'wait, I think actually I'm not ready and I just want to cuddle', because that presently advances our goals. That said, if Keltham ignores you about that, that would be great news for the project and you should make sure he has a really pleasant time about it and ends up with the impression he was right to ignore you. I strongly expect that if you try to tease him by getting him really turned on and then saying 'no' he'll just give you a hug and say it's okay, so if you are trying this route you're going to have to try something a lot subtler and cleverer than that, and you should run it by me.
We aren't telling him about the soul arrangements, but if he somehow learns of it, the line is that it's normal for people in dangerous lines of work to arrange their afterlife in advance so they don't end up in Avernus in general processing, and that as a bonus these business arrangements are hotly competed for among devils so a good negotiator can get some reasonably powerful magic out of making their afterlife arrangements. But that's only if he somehow finds out. I, and some of your colleagues, don't have arcane sight, because our contractual arrangements were a bit different; we're still working out the best story for that so for today you should conceal having it.
Other things you are explicitly expected to lie to Keltham about: who his god is. It's going to be an obscure Tian one. Whether all fourth-circle clerics have a weaker personal aura should they differ from their god in alignment; it doesn't come up much in Cheliax because it can't happen with an Asmodean cleric but you'd expect they wouldn't. Whether Cheliax is systematically concealing things. Whether Hell involves involuntary torture.
And, of course, everything to do with the character of Cheliax as a nation. We're going to be pretending that Cheliax is Taldor."
And she explains her reasoning, again, and explains the key outlines from the fake timeline and from the books about Taldor.
"At this time I'll take questions, but my plan is actually for you to spend the rest of the morning learning enough about Taldor that you can be a magic-tracked shut-in who plausibly lived there."
