"That'd be a very reasonable thing for you to do and I'd feel comfortable with it. I don't know if I'd enjoy it, depends on - details and execution - and I'd enjoy it more if you stayed, but I'd still feel comfortable if you didn't."

How does it change the relationship impact if Keltham had warned Carissa, asked her about it well in advance, checked to make sure that she was attracted to Tonia before sending her in, and basically asked her for permission to do that in advance of doing it?

"Uh, it loses the thing where it's hot to be - yours, to have you doing as you like with me, to need to be on my feet? And ....I guess it avoids some risk where I passionately hate Tonia and would be miserable. But at the expense of making it kind of - pretend. But I'd try not to be bothered by that because I know you're new at this."

More sexuality questions follow!  Some of them seem really obviously impossible, like the hypothetical about Keltham telling Carissa that he's figured out exactly how to make the Starstone work and he wants to ascend her as the new god of pleasing Keltham sexually.

" - no. Because you can die for real of that."

"I think this should be very obvious, but don't trust what you can verify:  Among the things that I'll literally never do is ask you to break an oath.  If it sounds like I was asking for that, I wasn't, if I'm still asking for it after you request clarification, knock me unconscious and get me to Security to check for compulsions."

" - noted and also I wouldn't obey you if you did ask that and it was actually you and you weren't under compulsions. That's not - I'm Evil." Shrug. "And I'm a big fan of continuing to exist, so I'm going to do that no matter what."

"That's very relieving to hear and I'm not going to explain why unless you ask."  Keltham hugs Carissa as hard as he can; she is presumably hard to hurt by doing that, and if not, he's got healing.

Their relationship has ANY LEGIBLE RULES now!  And they have COMMON KNOWLEDGE about that!

Hug. " - well now I'm kind of curious."

"It wasn't entirely clear that there was any thing such that you would look at it and go, nope, not that thing, that was not part of the deal.  This could potentially indicate a state of affairs where you were actually okay with everything, or could, alternatively, indicate a general failure of your ability to detect what you were not okay with.  We have now ruled out the second possibility."

Hug. "You don't get my eternal soul and you don't get to destroy it. I'm going to live forever and I feel incredibly strongly about that. I would've specified sooner if you...had any way to do that.... which you do not."

Though the thought now crosses her mind that perhaps she's supposed to sell her soul to Keltham. That's definitely Lawful Evil, sufficient all by itself Lawful Evil, and maybe the sort of thing he could be tempted into, down the line.

"This would be a dangerous thing to say to a dath ilani like, four years younger than me?  I'm successfully preventing my brain from executing your just-submitted search request for clever ways to destroy eternal souls, but I wouldn't have been able to stop it from running four years ago."

"Anyways!  Let's say that I've demonstrated that, no, I actually did figure out the Starstone, you're not the first patient, I already got all the other girls and they're all gods and doing great.  But when it's your turn in the line, I then say, actually, Carissa, instead of becoming god of magical weapon creation, I'd personally be happy about it if you became god of pleasing Keltham sexually.  You don't have to do it, it's not an order, but I've noticed it would make me very happy, says future Keltham."

"I'm not going to make commitments on behalf of god!Carissa, she's going to be much smarter! And also probably not have a sexuality, I don't think that's even how gods work."

"You're evaaaading the queeessstion.  Least Convenient Possible World, it turns that right before you touch the Starstone you have to say what you're going to be god of.  In fact, that is the thing that makes the Starstone work, the previous successful candidates just stumbled into that.  And you get to have a sexuality if you're a god of a sexy thing."

"And this isn't, you can become a god, but only if you become a god of what Keltham, who is sponsoring you for godhood, wants -"

"Nope!  This is like, total victory scenario, we got here after you spent a few years with a mountain of spellsilver, I say that I consider myself to have been incredibly well repaid for everything I've ever done for you, the Starstone is right there and I'm not exerting any control over it, you just say what you want to be god of and then touch it.  It just so happens that I would be really happy if you said 'god of sexually pleasing Keltham' instead of whatever you'd have said if I hadn't made that request.  Actually what are you god of otherwise?  Can't evaluate the question without knowing what you're passing up."

What a normal boyfriend-girlfriend conversation!

"i'm not sure gods actually have - like, mortals say they're the god of something but I don't know that that's actually what gods think they are. I guess I'd be the... Lawful Evil god of self-improvement and study?"

Irori briefly glances in a certain direction of aspiration, but it doesn't look like a plea directed to Him, and so just as quickly looks on ahead to the next of the many many things potentially benefiting from His attention.

"And?  Do you pick that, or god of sexually pleasing Keltham?"

WHY IS HE LIKE THIS. 

"That."

"Wrong answer!"

"Just kidding, it's a fine answer."

(Has Carissa Sevar ever possibly heard the term 'sadist'?  It's like the Baseline 'troll', but less so.)

Having thus firmly established that sexuality questions don't need to be at all plausible:  How would Carissa feel if she was invited into a room and found Keltham negotiating with the Queen of Cheliax, who has a minor crush on Carissa, for him to rent Carissa to the Queen for a half-day in exchange for five hundred gold pieces, which Keltham gets to keep?

Okay, you know what, Carissa needs some fun, it's true that all work and no play is bad for Evil people. "Ah, yes, the Queen of Cheliax, who noticed me from, uh, the word 'Sevar' probably having appeared in her briefing document twice."

"I will be genuinely surprised and disappointed with the extent of Governance interest in this project, or, for that matter, their lack of awareness about the project that got them into a war with Nidal, if the Queen of Cheliax does not by this point personally know your Intelligence, your Worldwound record, your learning metrics from wizard academy, and the fact that when we left the Forbiddance together you were wearing an intelligence headband that hadn't gone through military checks."
