"Yes!  A lot of them do have multiple planes, in fact, with at least one or two of them accessible without magic - going through another plane makes it a lot easier to travel between stars without using huge amounts of fuel or spending years in transit."

And if you use huge amounts of fuel, your home and destination will still be waiting years even if you aren't... but there's no need to get into that, at least not yet.

"I might want to change this later, but as a rough idea, could there portals between planets that appear in random places, remain stable for a while, then gradually shrink down and disappear?"

"There're a lot of universes like that!

"How long are you thinking of with 'a while'?  Usually it's on the order of a few generations or more, but it could definitely be faster!  And are you thinking magical or nonmagical portals?

"-- actually, should I just go on to the question about how common you want magic to be?"

"I want people everywhere to have access to convenient magic that improves their lives. Healing, mending, creating clean water and food you can survive off of, that sort of thing." Please please please

"Then that means High Magic, where it's woven into the threads of everyday life and many people - or more - will be using magic.  It'll be taught in your Royal Academy; you'll be able to use it and that won't really give you an advantage."

She isn't really surprised, nor disappointed at all.  Many of her favorite stories are High Magic.

"That's the only question on the checklist... but if you want to talk about how it works?  Say, whether people need to learn it?  Or whether anyone can learn it?"

"It would be good if anyone could learn the basics, and the basics included spells that give you the necessities of life - food, water, healing, shelter, weather resistance. Maybe contraception too. But if someone wants to use magic for something else, or learn to make their own spells, then that could take a lot more training."

The angel nods.

"So it takes some learning, but the spells for the necessities of life are simple enough that everyone can learn them as children... perhaps in school or perhaps from their parents?  And then there's more advanced magic.  Do you have any ideas about what sort of things that can do?  Who would be expected to learn it?"

"I think it could depend on the society! There could be a lot of different spells, with enough flexibility that people can make their own. It could be used to explore new territories, to play competitive games, to create art, to transport people or objects, create useful artifacts, enhance people mentally and physically... I think it should be harder to use magic to hurt people, and maybe magic should be easier when in a specific frame of mind that Evil people"- wait, why even have a world with Evil people, can you just not or do you lose something important -"or evildoers, would have a harder time accessing." Is there anything he can't even imagine magic doing, because Golarion magic is incapable of it? 

"I'm not sure what you mean by 'who would be expected to learn it.' Different societies might have different arrangements."

The angel nods along eagerly with Lac's list.  "Yes, yes, all that and more.  And its being hard to hurt people - I've seen a few worlds that've done things like that.  Maybe it'd cause bad blowback on the caster?  Or maybe people's bodies would just be resilient against magic?  That'd make some medical spells harder, but nonmagical medicine could easily fill in there, especially if you're in Space Opera.

"Some worlds have tried different frames of mind to make magic more powerful sometimes when a god judges it's used for Good?  Or when the caster's in a specific mindset?  Or a lot of worlds have gone with a fully emotionally-based magic system, though that has a lot of other effects on how magic works.

"And of course different societies would do things differently - I was asking if you had any thoughts who'd be expected to do that in Villarosa?  You're going to be a princess or noblewoman; would you be expected to learn advanced magic?" 

She pauses just a moment, and then adds more quietly,

"I'm happy to give you examples if you want?  Or, at any point, you can let the Worldbuilding Team fill in.  Or we can sketch something out here and then go through the rest of the list?"

"I think the world should have a benevolent God. Maybe with the restriction that they can't interfere in Villarosa until the story is over? But that would go a long way towards alleviating my concerns that the world won't stay good in the long run, or that the afterlife will get overcrowded, or something, if there's a powerful benevolent God who can keep it on track."

"Yes, that's a very practicable idea.  Someone who can think of many more options than either of us might imagine here.  And we can absolutely do that.

"Are you bound to the idea that this god can't interfere in Villarosa before the story happens?  The Worldbuilding Team sets up Fate, in some sense, to keep things on track until the story starts; it might be simpler for this god to help with that?"

"You've given some constraints for Villarosa, such that I think a benevolent God that shares my values would want to intervene to make things better, even if it does things like lowering the amount of social inequality. But a God should be able to bind itself with an unbreakable oath, so maybe this God could agree to intervene only in ways that support Fate, at least until the story is over."

"Or perhaps be themself constrained by Fate, or some other power...

"There's a choice later on, a Perk you can take to go 'Off the Rails' - though that metaphor wouldn't translate to you; perhaps 'Off the Road'? - but what it means is to largely end Fate once the story starts."

"Does that mean there effectively isn't a story, just normal cause and effect? And maybe we should go over the full list of options before we dive deeper into the worldbuilding."

Oh yes, she did say that, didn't she?  Before being distracted by constructing theology.

"That's why I said mostly end Fate... but you're right.  Next up..."

"... is your Fiance!

"You'll start the story - when you regain your memories - engaged to him, and if you win, you'll end up married to him!  Whether or not that happens will, of course, depend on you.  The Heroine will have a strong advantage - we'll be talking about her next - but you will have a chance.

"You'll start with a polite friendly relationship with him - he'll want to make the engagement and marriage work.  Not love, of course; it's an arranged marriage.  Unless you select the Perk that says he actually is in love with you."

She looks like she really doesn't want him to pick Off the Rails. Why is it even an option? Organizational policy?

He nods along.

(Yes, organizational policy.  All these options are organizational policy.)

She turns the pages of her book and half-reads half-paraphrases with emotion, with a grin on her face.

"First up, 'Prince Charming.'  The heir to the throne, a heroic guy about your age, talented, romantic by generally-accepted standards, will take offense at any nefarious tactics...  By any conventional standards, his wife is going to be a lucky woman.

"Second, the Dark Rival.  He could be the king's son or a duke's.  He's more talented than Prince Charming at the start, exudes romantic danger and dominance, can be mean but never quite evil...  Of course, because this is a story, he's got a heart of gold outside for the right woman to unlock.

"Or third, the Noble Prodigy!  He's older than you, already graduated and made a name for himself - ascending from lesser nobility to the heights of society.  What exactly he's done depends on the setting.  He's cold and formal and unemotional at first due to some tragedy in his past... but the right woman will melt the armor around his soul."

She looks up.

"But according to the story, the right woman is the heroine.  Not you.  That's up to you to try to change if you can."

"Prince Charming sounds like the most appealing option. Will the reincarnation process make me attracted to men? I'm already mildly attracted to men but not to the point where I would expend a lot of effort trying to romance one." Hopefully the Angel isn't one of the weird people who thinks men liking men is immoral. Probably not, as far as he knows that's strictly a mortal problem.

He doesn't want a sexuality change but that isn't very important.

She quickly nods.  "Yes, you will be once you're reborn as a girl in Villarosa.  Anything else would be too disruptive to the story, I think?

"And Prince Charming?  All right."

He nods along, not feeling great about the whole thing. Presumably he'll enjoy the romance when he gets to it. Which is also irrelevant - Lac would sell his soul for the opportunity to design a world like this, so there isn't much point feeling bad about something as small as a sexuality change and forced romance.

"What's the next option?"

The Angel gives him a sympathetic smile and turns a few pages.  Hopefully this next one will be a more engaging choice to make... or if not, at least the Perks will be.

She turns a couple pages.
