Here is a small round library that looks like it might be made out of a very large tree indeed, with shelves full of books lining its round walls.
There is a tiny blue unicorn flumphed on the floor reading a book nearly larger than she is - it's a pretty big book, but it is also a very small unicorn - and a few seconds after the traveler arrives, she looks up and blinks with surprise.
"Goodness me," she says. "I wasn't expecting that at all."
"I am!" she agrees. "I'm not at all sure what you are. I don't think I've ever heard of a sort of person who looked like you."
"We come in all the usual colours," she says. "Of which blue is one. But I guess if I've never heard of humans it makes sense that you, reciprocally, have never heard of blue unicorns. In fact, you're a step ahead of me in having heard of unicorns at all. Where are you from, and how did you get here from there?"
"You're perfectly welcome in my library," the unicorn assures her. "Oh - I forgot to introduce myself, silly me. My name is Blueberry; what's yours?"
"Did you come to the library in particular for a reason, or are you just sort of wandering?"
"Well, I happen to think the library is an excellent place to wander to," she says. "What kinds of books do you like? I like most everything."
Blueberry giggles. "That does sound like the sort of thing that happens in histories."
"I've never heard of any of those. They must be very far away from Equestria."
"Yes," she agrees. "It's perfectly logical, it's just also really interesting."
