Given the time that took, she'll go back to Valanda's apartment rather than the library.

"Learn any Hari while you were out?"

She did. Here's some words she picked up from so to speak immersion. Also some she didn't know the meanings of, including 'diabetes'.

Turns out Valanda doesn't know that one either.

Iri does! "It's a disease where, um, food is poison because something's wrong with one of your organs?"

There's more than one of those, does Iri have any specifics?

"I think you go blind and die?"

She tries out some Capital words for diseases. (Not the kind of thing she wants to be uncertain of, here.)

And now Iri knows what those Capital words mean!

Which would be really helpful if they knew a lot of Hari disease names. They can rule out some of them but not single out one of them as definitely right.

Well, unless knowledge magic can help that sounds as far as they can go with present resources.

"I'm sorry. Should I go, um, try to figure it out somehow?"

Iri has nothing to be sorry for. It's probably not that important right now?

In something else she's wondering if they know - do they know the approximate demographics of the different species of this world? She understands it's different in different places.

"I think more people are agerah than anything else but less than half of people are agerah. Beluli are the next most common, I think. Then caralendri. And humans are rarest."

How rare? And about how does it vary among different places?

"There might be somewhere between 6912 and 8640 humans in the Hari Empire. I think there are more agerah north of the mountains and more caralendri south of them."

Well.

Does he know why there are so few humans? Have their always been? 

"I think there used to be two or three times as many?"

Oh?

"...I don't have siblings, I think that's why there aren't very many humans."

Her Alpha and Protector instincts together have decided to take this time to tell her that this is an unsafe number and she should clearly do something about this. She puts them away appropriately.

Are they having fertility or pregnancy or infant mortality problems of some sort, or social problems, or do people just not tend to want many children?

"I think my parents wanted more children before they saw how I turned out."

He seems to have turned out perfectly well; is there something they found objectionable? And, is this a common experience?

"What a question! And what did your parents think of you?"

At some point she will need to make decisions about what story she can tell here. In the meanwhile,

They didn't particularly like her, and then something they didn't like about her became something that could embarrass them, and then they got rid of her and she hadn't seen them since she was fifteen. She was the second child, though.

"Yeah, well, my parents had their regrettable baby first. Anyway, I don't think all humans even have relationships with other humans, lots of people are happy with caralendri or something."

Sympathy to him.

Ah, she sees. It must be harder to find suitable humans with such small numbers, too. And they don't mind the lack of children?
