:But that's stupid! If you believe that, I don't know, the sky is green - or if you believe your mother was an incarnation of Astera, I had a patient once who thought that - it doesn't even hurt anyone!: 

Well, heresy does hurt people, it's bad for Asmodeus when people worship misconceptions of him and it's bad for Cheliax if we're not useful to Asmodeus.

:- How is it bad for Asmodeus if people worship him but they believe wrong things about him? What does it do?: 

I think it means us worshipping him doesn't do as much for his access to power and resources?

Jisa scrunches up her face in thought. Stares into the distance for a while. 

:...But I thought you said - serving other people's goals was Good? And Evil is when you have your own goals and try to get what you want. So why do you care what gives Asmodeus resources?: 

Well, if I were making the laws of Cheliax to be whatever benefitted me, I wouldn't ban heresy. But Asmodeus makes the laws, so he makes them prohibit heresy.

:Why don't you go live somewhere else with less stupid laws then: 

Well, I can live wherever I want, but I have less options for where I go when I die. And Hell's the best one, even if it's not how I would design it if I were in charge and doing whatever I wanted.

:- Well, I think I want to grow up and be in charge of an afterlife so I can make it better than Hell: 

Well, good luck with that. 

:We could all work together on it! You seem smart and so does Leareth. ...Why is his mind so weird, do you know?: 

Probably because he's thousands of years old and I assume has thrown all the intelligence enhancement your planet has at himself? They don't have headbands but intel when she was last in contact with her people didn't rule out applications of spells or Mindhealing or just regular Healing to grow your brain selectively.

(Leareth is not sure that it's a great idea for Carissa to be giving Asmodean ethical advice to the King of Valdemar's tiny daughter, but he's also way too tired to intervene, and has gone back to his frustrating attempts at extracting fluid and calories from a breast.) 

:I want to be smarter? Can you help me be smarter?: 

Yes, I could do that. Getting smarter is a good plan. It's useful for lots of other plans you might have.

Jisa frowns. Thinks. 

:I - have you already–:

And a Gate appears very suddenly on the nearby doorway. 

Carissa goes very still.

Nayoki steps through the Gate. 

Looks at the scene in front of her. 

A plump woman, with...her breast out? 

- and Leareth, sprawled on the floor, mostly wrapped in a blanket, but...suckling from the breast? 

And - a child of eight or nine, snuggled up against Leareth. 

Jisa turns to look toward the Gate. 

:Hi!: 

Nayoki glances around, then focuses on Carissa. 

:Who are you: 

The Alter Self picks this moment to end and now she's a different woman; Leareth isn't going to be getting anything out of her breast, now.

She is TERRIFIED and trying to be very not-threatening and think the important things very clearly. She escaped with Leareth from Valdemar. He's injured from Gating while already injured. She has a deal with him. 

Leareth immediately releases Carissa's breast and tries to sit up.

Nayoki recognizes this woman. She was with the group that grabbed Leareth just outside Iftel, the other mages shared memories of her face. 

She crosses the room in three steps - ignores the child for the moment, she has priorities - and squats to support Leareth's shoulders. He doesn't look especially capable of sitting up unaided. At least he's wrapped up in a blanket, and apparently alert enough to drink fluids. Also that's a very clever and creative use of Golarion magic. 

"What happened?" she asks him. 

"Long story." Leareth leans on her, closing his eyes. "Ask Carissa."
