It's good to have further confirmation that he can design whatever he likes, as long as he prevents it from being too much use in Villarosa. 

"What do you mean, balance the Perks with Flaws? Is it one for one?"

"Yes - there's another list of Flaws.  You get two free Perks, but you already used one of them on being an Elf, so you can pick one Perk for free here and every additional Perk must be balanced by a Flaw.

"Don't worry, you can always change your choices once you see the list of Flaws."

He reads over the list...

Lac's Shortlisted Traits: 

Early Start - More time to prepare. But he isn't sure if he wants to experience growing up as a child...

Equal Friend - Could be useful to have a princess as an ally, but probably he could cultivate allies even without that?

Good Ending - A convent might not be so bad, but even so- he doesn't want to be in bitter, winner-takes-all conflict with a Good person. Or even an Evil one, but the heroine being decent makes it worse.

Goddess of Beauty - If you're going to be a woman you might as well be gorgeous, right? This one is worse than the others, so he rejects it with slight disappointment.

Magical Prodigy - Giving up his talent would hurt. He's built around it in a deep way. Even if the magic of Villarosa isn't what he's used to, he still doesn't want to be merely ordinary at it.

Unearthly Insight - Flashes of helpful intuition!

"Tentatively, can I switch back to being Human, and take two perks?" He's not sure of the benefits of being an Elf, and some of these are really good. "Also, my previous aptitude for magic was because of my intelligence. Can this magic system also benefit from intelligence, such that I'll be highly talented even without Magical Prodigy?"

"Oh yes, you can absolutely switch to being Human!  And you can even say you're an Elf if you want to, as long as most people in Villarosa are also Elves - that's what the Will-in-Council is really getting at by saying 'Human.'"

"Though I'm afraid that if you try to say you're very intelligent and that makes you prodigious at magic, the Will-in-Council or Worldbuilding Department will say that's the same thing as picking Magical Prodigy.  You're not the first person to try something like that."

Wait, shouldn't he just make other people smarter in general? It would be really petty to make people stupid just so he can be smarter by comparison.

"I'll take Magical Prodigy and Good Ending, then."

"Just two Perks?" the Angel asks, her eyes wide.  "You're closing off so much amazing potential here!"

"Well, I don't know how bad the flaws are!"

That does make sense!  Maybe if he's super cautious... like he might be from suddenly finding he isn't in Specific Elysium after all.

She nods slowly.

"I'll show you, if you want?"

Some of those other perks are tempting. Nod.

She turns to another arch, spreads her arms, and it too expands, and a translucent sheet of what might be thin paper shows a list of each Flaw with its description.

"Don't worry about me if you end up picking Unprepared - I've seen people do it before, and I'm happy to watch them in their new stories anyway!"

Ditz, Jealousy, In-Character, and Magicless are all awful. Ghost in the Flesh seems Evil, as does Save the World. And...

"Am I understanding Late Start correctly? It's an automatic Bad Ending with no way to avoid it?"

"Yes!  Except you can get out of it if you want.  Some people like that challenge... and other people are happy not to.

"There was one woman who really wanted to be a nun, except there weren't any convents nearby in her homeworld that would accept her... so she made sure the same religion would be practiced in Villarosa and went off to be a nun there.  I think she had a satisfying time for a while before being martyred.

"Or, I heard from another angel about this one woman who was fine being a slave as long as she could design her perfect mistress.  I never heard the end of her story, but -" the angel shrugs.  "It could have worked out?"

That's fascinating and he really should ask more about the previous world-designers (discomfort, at how powerful Lila's organization is, how he can't do anything if they decide to stop playing nice).

"What's the strangest set of choices you've ever heard of someone in my position making?"

"Strangest?"

She stares into the sky blankly for a minute.  An aurora blossoms across maybe a quarter of the sky in the direction she's staring in.
