They have a lie prepared for that! The spell Carissa used is second-circle, here it is, it just detects Intelligence. he's welcome to try it. 

(None of Carissa, Maillol, Asmodia, or Security are at any real risk of failing their will saves against a scroll-cast Detect Thoughts.)

Maillol will, at need, send Carissa and Asmodia out and then tell Keltham flatly that yes, there's a third-circle spell that corresponds to Detect Anxieties and Detect Desires which does Detect Intentions, it's illegal, the second-circle spell he just used was invented by wizards as a way to get the useful Intelligence-detecting ability without the illegal components.

Keltham will eat, trying to maintain his continuing momentum and enthusiasm about what is, in fact, an attempt to destroy his new reality.  His mind will show a lot of repetitions of 'If the Conspiracy is real, I want to know the Conspiracy is real, if the Conspiracy is not real, I desire to know it is not real' and 'In worlds where this is actually a Conspiracy and Carissa never loved me it is better to know earlier rather than later' and the like.

He's trying not to think much about his plans for the Ostenso trip in the unlikely event that's allowed.  His mind briefly thinks something about Ostenso Academy and then deliberately thinks about how he's trying to throw out some false thoughts to confuse the Conspiracy and sometimes thinks this thought after both the accidental thoughts and the deliberate ones, and then he successfully refocuses his attention on the food and how much he doesn't want to lose Carissa.

His thoughts will also briefly cover how he's not even thinking, honestly hasn't thought about it, about whether making a hard try that ends up finding no Conspiracy would be enough info for him to think about kids.  He is not that absolutely confident that tropes don't exist.

Probably the Ostenso trip is a bad idea but in addition to the three bits it also buys them several hours. Carissa is torn.

- Korva's manning the Wall, can she work up a list of divergences between Ostenso and a similar city in Taldor and her best projection of alter-Ostenso.

When Keltham tests Detect Intelligence Carissa's needs to reflect her expected +4 and not her current +6. She could have herself dealt two points of Intelligence damage (temporarily) or swap the headbands out (this is painful to think about).

Aspexia is utterly confident of her ability to bestow a curse that precise, if none of the other clerics here have the spell prepped and are confident of their own skill.

Asmodia can feel a tiny note of terror in herself about the Ostenso trip.  Why.

It's huge, chaotic, hard to plan.  That, obviously, from Keltham's perspective, is the point - but it doesn't account for why he'd think Conspiracy was eight times less likely to -

If Ordinary probably won't go for it, maybe Keltham assigns 40% to that, so then he'd have to assign 5% to Conspiracy -

Asmodia is an idiot.  Either Keltham planted that thought for them to find, or he actually is that confident that this is an incredibly terrible idea for the Conspiracy for reasons the real Conspiracy hasn't seen.

.... Ostenso trip tomorrow. That's the solution. Keltham doesn't have any reason to think tomorrow's lots better for the Conspiracy than today, and there are obvious reasons even Ordinary would want to wait a day, so Security can have their spells prepared and additional Security made available. And that gives them an entire year to figure out why the trip is so dangerous and if necessary to completely rebuild Ostenso. 

Can alterCheliax really not secure a spontaneous version of that trip right away, if Keltham is calling in nation-level favors on it, if it's possible to do it 'tomorrow'?

There might literally not be any high level wizards or clerics with the requisite spells to make it safe, since they prepare their spells in the morning and already did so; it's not like Greater Teleport which you have other reasons to prepare. You'd probably want Teleport Trap to stop people teleporting in, which is seventh circle wizard and not prepared routinely, and plausibly Shield of Law or something which is cleric 8th. 

- actually, Carissa is delegating, to the Most High and whoever is the most senior wizard now on site, thinking of the spells that their alter-selves would use to make an Ostenso expedition safe.

Acknowledged.

Done with breakfast!  Off to Maillol's!  He really wishes that mindreading!Conspiracy hadn't picked up this much relative probability mass, it's going to make the whole day harder and less fun.

He deserves a cookie about that, really.

"Here.  I'm not actually comfortable with not knowing what Snack Service is doing using my body, so if possible and if it doesn't cost Ordinary anything, I request that sometime after this is over I get told what went down just now."

Keltham is already quickly biting the cookie, verifying the taste.  Apple-flavored, great.

"Snack Service says that the decision theory of this is too complicated for it to be telling me much, which is mostly what I expected."

So, on the one hand, that's better than Snack Service not being able to do that, which would've favored Conspiracy a lot - Snack Service is pretty high on the list of apparent-things they'd be faking.  But it again means that, in the Conspiracy worlds, it's narrowing down even more strongly on the mindreading Conspiracy and on them being relatively better at mindreading.  What with 'Snack Service' having apparently just read a thought, and one he was trying to hide.

Off to Maillol's office.

"Sudden trip to Ostenso.  I'm not going to ask whether it's possible, because it's obviously possible in principle, I'm asking you what ends up being the minimum cost and minimum risk."

"I'm not going to hide it, Keltham, I was wondering if you were going to ask that and I have literally had nightmares about you asking that.  Cheliax is still fighting the war that started when you went on one quick, tiny, almost certainly completely safe excursion three steps outside of our Forbiddance.  Don't get me wrong, it's a good war, a great war, the best, really, glad it started, but we are still in the middle of that one and I was sort of hoping to finish it up before you started the next one."

He's not lying.

"Ferrer."

"The main risk here is that this Project is cursed by Pharasma with respect to what happens whenever anything like this goes down.  I don't know how I protect you from that.  Intuitively, the way things go around you, it feels like literally nothing we can do is going to make there be a, in ilani-style numbers, less than ten percent probability, of Rovagug cultists or a Kuthite cell planted in Ostenso to get you or something completely unexpected going wrong."

He's still not lying.  AlterMaillol says it too.

"Is this a tropes-based prediction?  Because I'd mostly lost probability on those."

"It's a PROJECT MANAGER prediction."

"That is in fact about what I figured Ordinary was thinking, with respect to how I ended up tightly contained to a small location."

"Now talk to me about actual costs and how you'd do it if you had no other choice."  Again that flash of power, of pride, that his dath ilani instincts automatically try to crush down.

"Even if we trust the interdiction to keep out most of the gods, it's not impossible that multiple countries have localized something-interesting down to the Ostenso region.  The fact that Nidal invaded a site somewhere around here, to kick off the war and the god-war, that's something news has spread on even if not about Project Lawful specifically."

"There's dangerous things in the world that aren't gods, Keltham, that Broom's god isn't keeping out.  Subirachs isn't here to fight them off, she's here to die after hopefully longer than half a minute so reinforcements have time to get here.  If there's any shapechanged ancient dragons who decided to pass one of their endless years in Ostenso, just waiting to see if the cause of the god-war happened to pass by their tea-shop - I mean, there are ancient dragons with whom that'd be fine, but a lot with whom it wouldn't be."

"Just trying to protect you against a kidnapping cell planted by a Taldor duchy but one that has the ability to call in reinforcements to grab you - takes 8th-circle Shield of Law on you, ideally 8th-circle Mind Blank on you, if you can give us a wide area that's something like 160-foot by 160-foot ten minutes in advance we can put a Teleport Trap on the region and if we can't then I'd like to know how we're supposed to defend against somebody calling in a nation-level strike force that shows up standing next to you - I can run this past more experienced officers in Egorian but I mostly expect that our 8th-circle casters literally do not have those spells prepared today and yes I realize that doing it tomorrow gives everybody in Ostenso time to rehearse a story."

"What's the Queen do when she wants to travel?"

"First of all, Abrogail Thrune is an 8th-circle sorcerer herself and literally one of the five most powerful casters in Cheliax, second, she mostly stays in her well-protected palace, third, when she leaves her palace she teleports directly to somewhere else that's very protected, fourth, if she was violating those rules, she wouldn't do it on less than a day's notice."

"Conspiracy Asmodia already has everybody in Ostenso prepped with a story.  She's insulted that you think giving her an extra day of prep time is going to make a difference to her."

"I actually don't think she does? Ostenso is a port city, there are ships arriving from all over the world, there's no way Conspiracy is stopping them all at the docks to brief them. Unless Conspiracy rules the whole world, I guess, or at least the whole Inner Sea."

"You underestimate Conspiracy Asmodia... okay maybe not really, maybe not for that one."

"I don't know, I'd need a minute to think about how I'd handle that and Conspiracy Asmodia has literally had weeks."

"Is she any better at the ships thing if Keltham visits Ostenso tomorrow instead of in one hour?"
