It's a nice garden.

"To be honest, I feel very out of my depth here. I'd appreciate learning more about your organization, what they want and why, and what their usual methods are."

She watches him appreciating the garden, and his confusion... not so much subsiding as being pushed a little under the surface.  If she knew what he wanted to ask (is it something about Chaos and trials?  Infinity?  Communes?), she could help...

"I think everyone's out of their depth here - hardly anyone we pick has designed a world before!

"That's basically what our organization does:  designing universes and worlds and setting up stories in them!  At least, that's as far as I know; I wouldn't be surprised if the Will-in-Council is intervening in some of the universes beyond the normal operations of Story and Fate.  I don't know that for sure; the Will hasn't said much about what they don't do.  But this universe -"  She grins.  "No intervention here, I'm pretty sure!  If you want, you can even do away with Fate in this world beyond a very broad setup!

"What we're like...  I could list the departments, if you want?  There're the Angel-guides like me, there's the Worldbuilding Department, the Diplomacy Department..."

It sounds like he's being picked to design a world, full stop, not just give input on one? Is he being handed more power than Pharasma?? He wants time to think again but should probably keep the conversation going. "So you... pick people from existing worlds, and have them design new ones, then create those worlds? Are the worlds real, with real people, and not illusions? And what do you have a diplomacy department for?" Assuming all this is real and they aren't operating under strong constraints he doesn't understand, this organization is powerful enough to crush all of Golarion like bugs. Is there something else out there that rivals them?

"Sometimes, yes!  Sometimes we design them ourselves - or, well, other people do; I've never gotten to myself - but sometimes we choose people, yes.  I think the Will-in-Council and the Worldbuilding Department like to see how other people design them... and I think I would too in their place.

"And yes, they're real worlds with real people with real souls.  At least by default - if you want to say the world has some illusionary people, you can."

If he does, hopefully it'll go better than that one time where the protagonist guessed that and started dismissing the rest of the world as not worth any concern until she found someone she decided was the one other real person there...

Really, her guess about the motives of the Will of the Multiverse in Council is just a guess.  They aren't very talkative about themself... themselves... not even talkative enough to make clear why they sometimes take singular and sometimes plural pronouns?  Not that she minds; they've given her the best job she could possibly have imagined.  Elysium.  Er, in the metaphorical sense.

(The Worldbuilding Department is a lot more talkative - she has some friends there - but they don't know much more about the Will either.)

Hmm, speaking of which, maybe she should check why the Diplomacy Department gave Lac plural pronouns that one time?  But speaking of which, she has a guess there too...

"... I think we have a Diplomacy Department because it's nicer and smoother to talk with people rather than just wrenching them around?"

Holy shit he's going to DESIGN A WORLD, that's terrifying and incredible, maybe literally non-credible but he's already decided not to worry about Mephistopheles even if it's probably Mephistopheles. Anyway. He thinks she's telling the truth?? She could have the deceptive abilities of a succubus but worrying about that is kind of like worrying about Mephistopheles. And "That's a relief to hear, actually. It sounds like you're all very powerful and could do a lot of wrenching around if you wanted." Oh no that was probably too revealing aaaahhh.

"I know it sounds trite, but - don't worry."  She twitches her wings uncomfortably.  Really, she doesn't like people bowing down to her anymore, and people being visibly afraid of her has always been even worse.

"It's not like we're new.  Most universes will never be affected by us beyond, oh, how we lifted your soul out of your old universe and maybe sent a letter to some god there.  And I'm glad about that.

"Or if you must worry - maybe worry about your next life?"

Uh-huh. Worry about his NEXT LIFE instead of a WHOLE NEW WORLD with SOULS in it that has just become Lac's responsibility. He almost wants to laugh. It says something about this "angel"'s priorities, her narrow focus and interest in stories... if she's focused on him, then maybe he can make other parts of the world really, really good, so long as they don't interfere with the angel's intended plot? But he's just had a horrible thought. How to express it... Wait.

"I don't think I ever got your name? And what happens to the new world after my story in it is over, does it just keep going?"

"Yes, it's a real world, just like every other world; it doesn't just vanish when you're not there anymore!  I'd never set someone up to be causing that."

It's been a while since anyone's asked her for her name.  She's borne several in her time, but among those there's one from her human days that still speaks the most to her...

"If you want my name - you can think of me as 'Lila'."

Oh no, now he feels bad. He should treat her like a person with a conscience?? This is really high-stakes, bigger than either of them, but good faith is usually how you bring out the best in people, so it's still indicated. 

"Nice to meet you, Lila. Sorry, it's just - in Golarion, magic is resource-constrained. It's easier to make illusory objects than real objects, and easier to make a temporary effect than a permanent one. But maybe I need to drop my assumptions about how any of this works."

"I'm still glad to meet you too!"  She smiles to try to encourage him past his awkwardness with her happiness.

"And no need for apologies - you're just starting to learn how this works!  Magic usually does work that way within a universe... I've seen people who've set up other ways to have magic work -"

"- but usually the Worldbuilding Department has to set up strict limits so it won't make the world fall apart.  Uh, that's usually a metaphorical 'falling apart', but not always; I do remember that one world with really effective destruction magic.  But you won't get anything like that unless you intend to go there.

"Would you like to hear more of the outline for how this's set up?"

..."I'd like that." He gets to DESIGN MAGIC. Could he make everyone have ninth circle spells. That's a terrible idea. Could he give everyone Cure Wounds and Plant Growth and Alter Self* and Remove Disease and Remove Curse all as at-will racial abilities, or just not have diseases and curses in the first place, obviously he doesn't want diseases and curses and actually it sounds like maybe he could make his own spells?? Just decide what magic is able to do, like a tavern-drunk inventing stories about archmages?? Give everyone as many spell slots as they want, or make himself the only person with magic, or-

*Contraception.

Oh great, he's excited too now!

"One of the few things that are already defined for you is, you're going to be reincarnating into somewhere called the Kingdom of Villarosa, soon to have been the setting of the -" (he wouldn't recognize any closer name, so) "- romance story called 'Roses of Villarosa'.  As I mentioned, you'll be reincarnating as a teenager by default, and as the young woman who would have been the villainess in the story..."

She draws another book out of her magic pocket, and flips through a couple pages.

"You can start with your hair color and hairstyle, which is linked to personality here... or go on to the technology and magic of Villarosa and the world it will be in..."

He has so many questions! It sounds like the angel wants a monarchy and the Andoran in him objects, but maybe he can make sure the monarchy is benevolent?

"As a villainess, would I have to act Evil?" It doesn't matter on the scale of a whole world, but he really doesn't want to act like a Chelish heiress or something.

She can see he's got a lot of questions!

"No, no, not at all unless you choose to!  Except that you will be coming in conflict with the heroine - Fate will make sure of that, even if you choose not to have any Fate active otherwise.  If Fate is still active, it will be manipulating events around you... but not directly affecting your actions.

"Though of course you, or she, will have been acting poorly in some ways before you reincarnate into her as a teenager.  You can of course help define how, just like defining the rest of Villarosa."

That's all... fine?? He doesn't want to be the villain in a romance plot, but if he can just Not Do Evil...

He nods. "Am I displacing an existing soul? What happens to it?"

"... I actually don't know."  She feels sort of uncomfortable admitting that.  "Maybe the Operations Team does it differently different times.  They haven't told me.  There is an option you can choose to have her stay around as a voice in your head, so I assume in those cases she would be a different person and soul... but if you don't choose that, I don't know.  Maybe she's you, without your memories and with compulsions and Fate more active.  Maybe she's a different soul and the same thing happens as with every other soul..."

"... which you can decide, if you want!"

Nirvana is for everyone. Except he can do better than that. What if everyone had their choice of paradise instead of sorting by alignment. What if everyone could Plane Shift between paradises, so families don't have to be separated.

He still doesn't want to kill someone when he reincarnates. You only get one life, and that makes it valuable even if you go to paradise later. (Ideas start leaping through his head for a reincarnation scheme).

How many souls can he put in paradise. Can he put millions, billions, a literally infinite number of souls in paradise?

"I'd like that. I want everyone to have a good afterlife."

He is more powerful than a God and his slightest mistakes will harm millions of people. Maybe more.
