The Splendour wore off sometime while the second Nefreti was talking, and Keltham's emotions feel diminished, now, by comparison, along with the drive that was holding them in check.  It's not really challenging some of his earlier sense that messing with your 'mental attributes' is not all that safe for people who want to keep their personalities intact, especially if you raise and lower them on a daily basis.

"You want to swear to me about how you're bound by Cheliax's agreement not to interfere with my attempts to leave nor buy passage, and that my telling you what I'm doing won't hinder my goals as I currently see them?"

"Actually no, I'm not particularly loyal to Cheliax, which they know.  I could easily end up seeing myself as a free agent not bound by Cheliax's agreements."  There are things Asmodia could swear to, but to swear to anything that provokes Keltham's incredulity - might lead him to doubt oaths, which might not help Cheliax at this point.  ((More importantly, it might not help Keltham, given his mental state.))

"Conjecture, you're trying to get outside the Forbiddance they claimed was here, in order to use Summon Monster III for the next step of a plan you did a really impressive job of never thinking about.  I don't think there's actually a Forbiddance up, here, they didn't have time, also I think that does block Gate.  I worry that you are about to go outside the scry wards."

"If you want a minute to persuade me that's a bad idea, it's going to cost you a Teleport scroll."

"I don't actually know enough about the larger situation of who might be looking for you to say specifically why it's a bad idea.  I was just noting the point and that I'd expect Summon Monster III to work here -"

"Not taking the risk of wasting it" plus this might not work if he can't be scried Keltham flings open what looks like it might be the front door of the temple, and steps out.

Small village on a smaller river.  In the distant hills a herd of goats are visible, grazing. 

Keltham briefly considers the possibility of trying to talk to any of the few visible people, decides against it, keeps walking.

He'll walk until he's three times as far from the temple as the (supposed) radius of the Fortress's (supposed) Forbiddance.

Carissa follows him, silently. It's some time to get her head in order, at least.

"Let's be very clear about what I am about to do.  I am leaving Cheliax.  I am trying to buy my passage.  Anybody who violates that stands in breach of my contract with Cheliax and, I assume, ends up screaming in Asmodeus's Hell, which is not a threat by me, but does appear to be the way things work around here."

The way it works is that they end up screaming in Hell either way, Keltham, it's just worse if they disobey.  Asmodia will not say that unless instructed.

She should go ahead and say that. It's not like he won't hear it shortly from someone.

"They end up screaming in Hell either way, Keltham.  It's just worse if they disobey."

He's going to live mentally in the world where that's also a lie, for a time.  Not assign it any particular probability, just, hold off weighing that until later.

"They.  Not you?"

"Among the things I was promised in exchange for working hard was that they'd Plane Shift me to Abaddon instead."

"I made that deal before I knew about your theory of why I'd end up somewhere else.  I'm not really into pain."

"Okay.  You can also stop talking now."

Summon Monster III!  Lawful Neutral outsider if available, otherwise, lantern archon!

Lantern archon!! Bopping, bewildered, in the air! "Hi!"

"Hi!  Recognize this symbol?"  Keltham draws his truthspell-symbol in the air with one finger.

"That's one of the holy symbols of Abadar!"

"I'm a fourth-circle cleric of Abadar from another world, inside I'm told a zone where gods can't interfere.  I need to get out of Cheliax after finding out what Evil is actually like.  I have a lot of valuable knowledge including about spellsilver refinement.  Cheliax is hopefully compacted not to interfere with my departure.  When you go back, I want you to talk to whoever's above you in Heaven and try to get a message, not to the god Abadar, but to the outsiders He employs, who could get a message to Abadar's people in Golarion to pick me up here.  Without that message blocking on anything too godlike to interfere here.  Up to two thousand gold for my passage, my people can maybe do loans if that's not enough.  I've got up to five hundred gold to pay for passing this message.  Can you do that?"

"I don't want your gold! You should donate it to a church here that's doing Good things and helping people, if you don't end up needing it to get out of Cheliax! Cheliax is a bad place! I will convey your message to Heaven but not to any gods because they can't interfere!"

"I will so donate, if the message gets through.  Can Heaven get it to Axis and Abadar's people, is my question, and do you know how long that'd take?"

"I think so but I don't really know!"

....and the archon vanishes. Summons don't last very long.

Then he'll sit down where scries can find him, and wait.

It isn't long.
