Abrogail Thrune feels, now, as wretched, as unhappy, as powerless, as ruined, as at any other point in her reign.  As wretched as when she called her halt in Hell with six circles of sorcery to become eight circles, having hoped for seven to become nine, and proved too weak for that.

She does not weep, for she's never once wept since that time; and she will not give the tropes the satisfaction.

She does not think about Carissa, except as her opponent.

(Aspexia Rugatonn hasn't told Abrogail Thrune about Carissa Sevar's last claim to still be serving Asmodeus in a complicated way, any more than Aspexia has told Pilar.  If Aspexia has understood tropes at all, you're not supposed to give people hope about that sort of thing, it can't come true if they're already hoping for it.)

She absolutely does not miss Carissa.  Abrogail Thrune was never Carissa's friend or even her ally.

They're in a romance novel, now, and romance-novel characters who think thoughts that pathetic don't come to good ends.

Carissa Sevar was her finest creation, and Abrogail Thrune was proud of her and took pleasure in corrupting her further, and that was their relationship, period.

She cannot abide this, she cannot sit in her library and wait for the hour of doom.

...she'll go make sure that all of her guards are those who've read Carissa's mind, whom Carissa now has a contractual right to buy from Hell with approval of Church and Crown.  When Carissa glossed that as "exercisable only with your approval and Aspexia's" did she realize what she was glossing?  Almost certainly not, at the time.

Carissa could try to connive those guards into slaying Abrogail, and take the throne, and buy their souls up from Hell afterwards with her own self's approval, once she was herself the Crown.  So long as she was planning to betray Keltham too and become a Power of Hell at the end, so long as the Church would approve of her reign...

Abrogail is willing to play that game.  She'll grant Carissa the opening move in it.  Yes, it's folly, but -

Abrogail doesn't miss Carissa.  She wants Carissa to come back and finish their game, because it advantages Cheliax and Asmodeus if the plot turns in a way where Carissa plays at all no can't think that either any hopes she thinks won't come to pass without complication -

...is she actually at risk of going mad, like this?

She shouldn't be.  She'll think like this for a few days and get used to it and her thoughts will shake out.

She's been to Hell and back.

She can handle this much adversity.

Osirion

The head of the Risen Guard is displeased to have the Dome housing a fifth-circle wizard wearing an artifact headband straight from Hell that cannot be removed from her person and functions even in an antimagic field. He is further displeased that she is unwilling to swear that her purposes are not opposed to Osirion's or even that she won't assassinate the pharaoh. 

Normally any two of these hesitations would be sufficient for the head of the Risen Guard to simply refuse to let a person in, but they can't exactly turn this one away. Even if she's probably here as part of an infernal ploy of some kind to win Keltham to Cheliax's side in the impending war. Even if there's a bizarre cult that the council just banned in all of Osirion, claiming that she and Keltham and some other Chelish person will ascend together.

(That's not the claim it got banned for. It got banned for claiming - falsely, as far as anyone can tell and as far as the Church of Asmodeus says - that Carissa Sevar's followers will find mercy and healing in Hell. Osirion is not particularly sympathetic to any falsehoods about afterlives but falsely telling people Hell isn't very bad is well over the line.)

Carissa Sevar is bound (in a modesty-respecting fashion, with three cloaks draped over her in case anyone would find the ropes sensuous, so she resembles a very beautiful head poking out of a burrito), and gagged, and her guards are deaf, and she's in an antimagic field, and the handcuffs she's wearing were Polymorphed into a solid stone block with an eight circle spell that is, importantly, permanent rather than instantaneous, which means that if she's somehow gets out of the antimagic field the spell will cease to be suppressed and they'll sever both her hands. 

Furthermore they have used the spell Touch of Idiocy to temporarily reduce her Intelligence to 9, which will kick in if she leaves the antimagic field so she can't cast spells. 

The head of the Risen Guard has warned the pharaoh that he doesn't actually consider this adequate security. Artifact headbands out of Hell can ignore antimagic fields, and the headband has some spells built in; the only ones he can see are Banishment and a used True Seeing, but artifact headbands are also known to not always reliably report their capabilities. If she has Major Image and Gaseous Form and Greater Restoration in there, all their precautions are for naught. And if Hell planned this, Hell planned for Osirion's obvious precautions. 

" - okay, I know Keltham said not to do him favors, but I'm very worried about pushing him over the edge if we mistreat his woman by dath ilani standards, so be careful."

"Those are indeed the considerations I'm balancing, though I'm much more worried about what Sevar's trying to do than about the immediate effects of having her - what's your thinking -"

"...probability we lose the war with Cheliax is up, probability of the world getting destroyed is down. I assume the thinking there is that if Keltham gets corrupted and starts working for the forces of Hell then he isn't letting Rovagug out in a fit of teenage righteousness, which I must say I don't find reassuring."

"I find it slightly reassuring. Is there - any form of interference you predict makes things go better."

"Calling Derrina, which we'd in any event committed to doing once we got Sevar. That's it, at least until Keltham gets here."

Derrina will get that Sending and reply back that she'll be there in a minute.

Then she'll pull out her magic items and start cheating until everything hostile around her is dead, which doesn't take long at all once Derrina starts cheating.

She'll Prestidigitate all the gore off of herself, in case anybody present cares about that sort of thing, and then Teleport to the reception area right outside the Black Dome.

She's expected. She can come on in at once. 

"I see they fear you appropriately," is Derrina's first remark upon seeing the Carissa-burrito, as she goes about removing the gag.

"I sort of think none of us are afraid enough.

...this is no concern of yours, but it's time-sensitive: one of the bodies in my Bag of Holding is an ally, and I want him Raised and then possibly petrified. I can pay for it; I can do it myself, if they give me a Limited Wish scroll, and it might be better for it to be done by a Lawful Evil caster. It's time-sensitive because he's in Hell and they might refuse resurrection if they conclude I betrayed them."

"Keltham has been very insistent that nobody help him unless they're Lawful Evil, though of late he's made great exceptions and not explained.  Are you abiding by anything like that rule?"

"I think Keltham abhors the thought of trading with someone for power he'll use to their detriment. I'm Chelish. If you deal with me, you'll get what I offered and maybe also enable me to conquer the world, I don't know. I make no promises there."

Then Derrina will excuse herself a moment, and go convey to their hosts Carissa Sevar's urgent request to pay for, and cast from, a Limited Wish scroll, or have Raise Dead cast by some other Lawful Evil caster, in order to resurrect an ally in Hell before Hell concludes that Sevar betrayed them.  Along with Sevar's caveat that she's not making any promises about whether anything she trades for will enable her to conquer the world.  And Derrina's personal note that really Lawful Evil people will not usually be careful to warn you what promises they're not making.

Well, they might if they're trying to convince everyone they've defected and can be trusted. 

Osirion has Lawful Evil wizards and some priests of Abadar, though not many of them; usually, they are young and intend to fix it before they grow old. The request, on short notice, will run about 10,000gp, results not guaranteed, and they'll arrest Sevar's ally once they raise him.

Well, she'll take that back to Sevar, then.

Why are they even CHECKING with her she SAID she wanted it done, "yes, I'll pay them. They can take spellsilver out of my bag if they want it up front."

...Derrina can predict that the Abadarans are going to insist on having Sevar approve again the amount of spellsilver they want at current wildly-fluctuating Osirion prices, and she can predict that Sevar's going to approve it, and she'll trudge through all those motions while they fetch a Lawful Evil caster and get him set up.  Which of the three bodies in Sevar's bag are they supposed to Raise, and does she want anything in particular done with the other two?

"Curly hair, square jaw, missing most of his torso. I don't want to raise the other two, they're not mine."
