Suspicious.  But also a plausible security precaution for a much less Lawful world.  "I'm on board with that for month one, at least, yeah.  Okay, so my current schedule looks like... get a preliminary reasonable-looking contract drawn up on noncopyrightable basic info, with any dangerous-looking provisions not going into effect for a month during which the contract can be renegotiated by mutual consent.  Then give a lecture on some basic stuff, get informal social credit, scale up resources.  At end of day, apply all the enhancement spells and try to learn basic spellcasting.  Oh, and also, if there's some safe way to cast some of my other spells to find out what they are, like the enchantment-compulsion spells that are hopefully for symmetrically-fair-negotiation, maybe try that too."

"Enchantments are safe to test on people, they only last a minute and don't have long-term effects. Abjurations -" She's apparently lost concentration on her illusion while trying to explain to Keltham that women aren't people most places. That's embarrassing. "The illusion ran out but abjurations are protective magic and also safe to test, we can look through a book for examples. Illusions are safe to test. Conjuration and evocation and necromancy are all a bit risky but you could try 'em on a goat or something."

"There's one first-circle spell I've got more than one copy of, looked to me like enchantment-compulsion.  Let's go ahead and test that one, in case using another of the copies is relevant to negotiating the preliminary contract on the default plan for propagating basic info... anything special we should do to test it?"

"Uh, if you're not trusting us then probably you want to ask your whole gaggle of girls to look and write down what they think is going on with it and that'd make it harder for anyone to lie? Otherwise not especially - you'd want to tell the person you're casting it on, so that they can avoid instinctively trying to break it when it's cast."

"Not quite sure I understand your proposed procedure... I think maybe possibly the spell targets one person that I touch?  I don't have enough copies to cast on all the researchers."

"You're quick at spellcraft," she says approvingly. "Just in front of them while they have Detect Magic up so they can see it cast and make their inferences. Probably they got you girls with decent spellcraft." Is calling them 'girls' too unsuble? Does it even connote childishness across the magic-bridged language barrier? Is his a society that considers it a disadvantage for women to be in their twenties? - not the most important thing right now. Well, actually, plausibly the most important thing for Carissa's interests here but not the most urgent. "Doesn't matter who you cast it on, you can cast it on me if you like, but everyone who sees it ought to be able to guess what it does."

"Part of me feels like I oughta have something more - planned, for investigating stuff like this.  But yeah, let's just go do it instead of preparing.  We'll see if anybody's in the library, I guess?"  They're really going to need a research chamber with proper whiteboards at some point.

"Sure. That's the best place to find wizards, if there isn't a big round stone tower around."

Keltham tries to walk to where he roughly believes a library ought to be, theoretically speaking.

He has the floorplan of the place approximately right! It is not nearly as cleverly full of nooks and secret passages as one might expect from a sprawling palace for an Archduke, or if it is the secret passages are very well hidden.

They're followed by the security staff, who have probably figured out a plan to subvert whatever spell Keltham has. The least complicated thing would be dismissing it but some enchantments leave an indication of whether they're active. Dismissing it with an illusion to cover for it? Supressing it, more complicated than dismissing it but less likely to have any magically perceptible effects.... not her job.

The library contains a bunch of students. They're very pretty. They're delighted to see Keltham.

Definitely gotta hurry up on certain negotiations.  "So, today's agenda.  I'm planning to dump a bunch of basic knowledge on you all - and on anyone else who wants to listen in, I guess.  But first, gotta work out a contract covering how stuff like that propagates and gets passed on, because it's not the kind of thing that makes sense as a trade secret.  And before I do that, I ought to check the result of casting an unknown first-circle enchantment-compulsion cleric spell that wasn't in the textbook of first-circle cleric spells, in case my god gave it to me for negotiation purposes.  Oh yeah, I'm a cleric now, don't know which god yet, that happened."

"So, uh, any volunteers to be the test subject and report on the felt result?  And let's have, say, three people with Detect Magic independently write down what it looks to them like the spell is doing, if that makes sense - maybe it'll be obvious what it does, but if not, it's better to have three independent components on the opinion, without the opinions cross-contaminating each other.  That's an example of a kind of general procedure I'll be covering as basic knowledge."

There are a bunch of volunteers to be the subject of Keltham's enchantment, from the categories 'girls who think that's hot' and 'girls who want to be helpful' and 'girls who have never in their lives refused to volunteer for work at school and are pretty sure you go straight to Hell if you ever do'. There are also some non-volunteers, mostly from people vying to be one of the ones who writes down what they think the spell is doing.  

Why are there so many of them. Is that really necessary. The school uniforms are not cut like that in Corentyn. ...they're probably not cut like that in Ostenso, either, bored teenage girls can get up to a lot of uniform adjustment.

It's kind of awesome how everybody in Cheliax competes to be the one in front as soon as any problem comes up!  It may be less efficient than the dath ilani reaction of everybody carefully figuring out who's the optimal candidate (or alternatively just picking at random, if the consumable variation in expected utility from additional search doesn't look worth the meta-overhead on a quick meta-meta glance).  But it's so much more energetic!  The Research Horde's enthusiasm and eagerness feels contagious.

Keltham randomly picks one volunteer and three people to write down the spell effects, since this is pretty obviously a case where the overhead cost exceeds the consumable knowable variance from his perspective.  It's not like he's really figured out how to tell these people apart yet.  At some point soon Keltham is going to have to explain the concept of "nametags".

Then the volunteer to get the spell cast will come over and do the practiced mental motion of not resisting a self-affecting spell and the other three will get out notebooks to scribble down the spell structure and cast Detect Magic so they can see it.

Keltham focuses, and tries to cast that thing he has three copies of.

There's a feeling-of-magic, now that that's a thing he is accustomed to feeling for, and a glowing symbol appears on the girl's forehead. She blinks.

Neato, Keltham supposes?  Keltham waits a moment, to see if the volunteer wants to volunteer any info on what the spell seems to be doing to her.

"It's not immediately obvious what it's acting on - probably stops me doing something, rather than making me do something -"

It's a truth spell. She does not volunteer this. Keltham's god gave Keltham a truth spell. As - a way of protesting that they're lying to him, presumably, but - does it mean he'd take the truth well? Or just that his god doesn't care for him to work with Cheliax?

Are we allowed to tell him, one of the three girls taking notes thinks loudly in the general direction of whoever's presumably coordinating here.

There isn't an immediate answer, possibly because they are debating that themselves.

Keltham tries to think fast, since he's not sure how long this spell will last.  This spell is either going to be useful for bargaining, or useful for finding out something else that his god wants him to know.  Let's try the more innocuous one first.  "Have you got anything on you that you own, and can offer to sell me for a ludicrously huge price?  Try doing that."

"- uh, sure. This is my shoe and I'll sell it to you for eighteen thousand gold pieces." The illusion doesn't waver. "I don't think it triggered."
