"Perhaps fire could combine with different things to form either life or death?" she offers lightly.

"And crumbling Earth... yes, either slag or dead spent ground that doesn't grow anything.  I saw too much of that in my first life..."

She hasn't remembered those memories for a while, actually.

"Deathly certainty sounds to me more like a ghost or vampire-in-some-forms, who stays in a frozen instant and doesn't change.  Deathly decay would be staying in the world without that fixture to keep you in that certainty - and yes, there would certainly be ways to do both.  Maybe a magical green lantern, though I don't catch the 'green' part?"

(Magical lanterns are also bringing back very old memories she hasn't thought of for ages.)

"I mean, 'fire combining with things to form either life or death' is kind of - backwards?  The elements arise from the principles, they don't give birth to them - though Fire in particular tended to inspire some very fucked-up druids in the game's canon, I tell you what."

"Still, --

"Hang on, your first life?

"Like I've still got some - places where you're not following that I want to circle back to - but did you reincarnate here?"

"Yes, and it's wonderful!  I had a good first life, and then that story ended... or, well, passed on to other people... and now I can see so many other stories and even help put them together!"

"That does sound fun."

"Yes! ...   So fire comes from light and Chaos and either death or life?  That makes sense too...  What would it look like to invoke this sort of magic?"

"...Here, let me get all this down properly."

The angel steps back, running her hands over a quill pen that's suddenly floating in the air in front of her.

And Alicia finally renders a proper diagram of her cosmology!  Well.  It's kind of not her own cosmology, it's just something that's been heavily remixed by her hand.  But it's still a cosmology she put in some serious work on!

The diagram looks something like this: (Large image within)

Something's shifted back with the angel now.  Just like it was at first, her hair is now straight, and her wings are held as steady as rock, and her eyes are... muted, perhaps, or shielded.

"This's going to select for a specific sort of universe-building team... but once the right people are on this, they're going to enjoy it.  You've put in so many details and so many relationships!

"Do you know what the magic is going to feel like to the users?  Or should that be a surprise?"

"I mean, it's - it would have to be kind of - primordial, I think?  There's -"

"It's...Every sort of magic, is touching upon something fundamental to the universe, in a way - and there's going to be differences between the clicking, whirring gears and memorized equations of Arcane magic, or the livewire rodeo that's touching primeval Chaos and bending its course commonly known as Fel, or the terrible, grasping certainty of Death magic, when you feel it and not the sickening ease of Decay...or the communion of purpose in Spirit magic, whether with another or yourself!

"The only answer I have to 'what magic should feel like' is 'unique and thematic', you know?  And I feel like I can hardly describe it any more than they should be able to, to the people who've never reached out to sieve order and reason from the Twisting Nether, to the people who've never seen the manifest λ-possibilities of the Void - to the people who have never felt the higher purpose of the Light deign to align with theirs.  And it's - that's important.  There must never be a time when the wonder truly dies, when - when magic becomes boring.  Safe, maybe, but boring, never!"

"And if you want something that's more actionable than an impassioned speech I bet I can get you something, eh?  Just give me a minute."

Nota bene: λ is often also spelled "𝒩ot", which is often rendered into a human-pronounceable form as "Not".  This is, of course, not to be confused with a mere "not"; what is Not is not some mere negation.

She bows her head and wings...

... and remembers something that might be similar.  "Yes, the touch of something bigger... but also the touch of something foreign...  I'd say you don't know what you're letting yourself in for, but you said it yourself.  And I don't know either what they would both feel like together, let alone filtered in these interesting new ways."

"Well then!  What about the rest of the world?  At a more human-scale?"

"...You know, I have absolutely no idea how to construct a - human-seeming, for a value of 'human' that mostly means 'includes the petty and/or greedy dumbasses' - polity?  I am, if anything, too idealistic when it comes to my expectations of social behavior invented de novo, especialy when I'm thinking about it from a perspective of authorial fiat, rather than dealing with what Earth actually practiced.

"Then again, I suppose I could make this a world where people within it Do Just.  If I really felt it necessary.  All the same - it would feel alien to...

"Hah.  Maybe that's the culture of the metaphorical blue-skinned alien space goats.

"Which are a literal reference, to be clear, so probably they should not be blue-skinned alien space goats, if they show up, y'know?

"Anyway - where was I...

"...Hey, do you have experience with high-magic but feudal-ish societies?"

She notes down the metaphorically-blue-skinned goats, with a note that they should have pink skin and blue fur.  At least.

And then she blinks.

"We didn't really have high-magic in my first life - just Medium, by this standard.  I had magic, and some of my friends wanted to give everyone magic, but we couldn't.  I've watched some high-magic worlds, but  --"

"But?"

"... but that wasn't what you were asking, and anyway, the Will of the Multiverse wouldn't let anyone help you at this stage.  Only people on the universe-building team, or people who're actually going to be reincarnated in Villarosa."

...Would the angel like a hug?

"Well, are there any of those we can sneak you through?"

She tenses for a moment, but then leans into the hug.

And then she has an idea.

"Yes!  I don't think I mentioned, but even without reincarnations, sometimes there're slightly-different versions of the same person in different universes.  We call them 'alts.'  I can get one of my own alts here and send her to Villarosa with you!"

"Oh, yeah, mhm?  That'd be nice, I think; you seem a good person to have around - but, um, how would the mechanics work?  Being as this is the Villainess CYOA I'm in, and - I wouldn't want to subject her to bad insert-life."

Meanwhile: Hugging the angel!  She's a very good angel and richly deserving of hugs.

She likes the hug, and (if Alicia will accept it?) hugs back with her wings.

"Oh, there're a couple options.  I'm sure any alt of me would love any one of them.  We could double up Villarosa and make there be two villainesses, both you and her - the most complete way would need more resources from the Will of the Multiverse, but there're other ways.  Or, we could put her in as another character... for the most independence, perhaps the original Heroine?

"And I'll try to find one who is from a high-magic feudal world..."

Meanwhile, she's trying to think when would be best to grab her alt.  If she came from before the first arc of her story was finished - while still fighting the invader - she'd have the freshest attitude in some ways and perhaps play best in the story.  But then, she thinks she'd accept it, but she probably wouldn't actually welcome being whisked out of her world with that arc still incomplete and Barvid still ruling.

Alicia absolutely would like to be hugged back with wings.  "I think I'd place her as the Heroine, if she's amenable; being able to co-ordinate with my opposite number on how we're going to handle the otome elements - or rather, the light novel otome parody elements - would be pretty useful."
