"Ooh. No. Hmm...there should be other types of feet too. What about, like, dinosaur feet." 

"I do not know of dinosaurs!" she says, intrigued. "What manner of feet do they have?"

She considers this. 

"Can I have, like, paper and a pencil?" she asks Tabitha. 

"Of course!" She opens a drawer and retrieves a blank notebook and a pencil, which she passes across the desk.

Lucy takes them carefully, flips the notebook open, and starts sketching. 

She isn't a brilliant artist, but she manages a drawing that competently demonstrates a leg structure that she has been informed is pretty close to a T-Rex. 

"This is what my brother's legs looked like!" she says brightly, showing the drawing to Raivethrani. "It's probably different from real dinosaur legs in some ways but it's what I know best and Mama said they were like dinosaur legs."

"I think those would be lovely to include in our population," she says. "In fact I'm starting to think that we should invite the - 'worldbuilding team', was it? - to include all sorts of variations like these, even ones we haven't thought of, so long as they're reasonably comfortable and practical, and with enough variety included and enough of all that variety that no one is left in the unfortunate position of having a type of body that no one is designing furniture for. Or architecture, for that matter—imagine all the trouble one would get into as one of only a handful of wingless people in a winged society, or as one of only a handful of people with snakes' bodies in a society of people with legs!"

"That would be bad," she agrees. "Oh! And we should have--I don't know how good your species's larynxes are but there are a lot of pretty sounds I can make that humans can't."

"Would you like to demonstrate, so I can see if I can mimic them?"

She mimics some especially charming bird song she's heard, and then--

It isn't a perfect reproduction of a church organ; she's only heard one from far off. But she knows the version she's heard isn't quite the full effect, and she fills in the gaps with unearthly echoing tones of her own imagining. 

"Hmm! No, I don't think I could manage that," she says. "By all means let's all have such magnificent voices. Meanwhile, how well can you see in true darkness? I quite like my own people's ability to perceive colour without light."

"I don't know! I don't think I've ever been in true darkness, there's always been stars. I see fine by starlight though."

"Well, I want to keep my own darkvision, but you needn't follow my example if you don't feel like it. Perhaps varying types of vision would also be good to have."

"I don't know the vision I have now would work in the dark, but I'd like to have vision that does," she says firmly.

"It would be nice to be better able to tolerate very bright light as well, while we're thinking of improvements," she muses. "Assuming that the one is compatible with the other."

"The worldbuilding team shouldn't have any trouble with it," Tabitha assures them.

"Can you not tolerate bright light? How bright is bright?"

"I've only left Shadow Mountain a handful of times, but the light of the sun outside its shelter of clouds can get uncomfortable, and any brighter than that can be a real problem. It's a trade I'm happy to make, for the beauty I see in the dark, but I'd rather not have to."

"When I was little I loved to play in the snow, and one thing that's brighter than a sunny day is a sunny day where the sun is reflecting off the snow. I can handle that fine. I think if I had to pick I'd take handling bright light over not needing starlight to see by, but of course it's better not to have to pick. Umm. Does your species have monthlies?"

Quizzical blink.

"Do you bleed from the junk once a month. Or at some other frequency."

"...not by default, certainly—is this a human problem?"

"Uh-huh. I don't have it but Mama did."

"Let us by all means omit this human problem. I suppose there's someone out there who might want it, stranger things have happened, but if so they can invent it themselves."

“This is a problem you can solve with a pointy stick,” Lucy agrees. It occurs to her after a moment to say: “So I think we both pick elf, what’s the next thing.”

"Hairstyle and hair colour, but the range of styles is different depending whether you're a villainess or a heroine—have you put any more thought into that?"
