"Large Cursorial Predator Bird, approximately Four Times your Height. Nonsapient. Often used as Mounts."

"Oh. Interesting."

She pauses for a second.

"Do you like being Undying?"

"I used to Be a Regular Badger, of the Nonsapient Type. I much Prefer being What I am Now. Being Undying is Somewhat Uncomfortable, but it Comes with Many Advantages."

Haria pauses, and wiggles in thought.

"I do."

"Twilight says that being unliving is very painful. Maybe you aren't actually that, but—hmm. If you could be sapient, but alive, would you want that?"

"Do Ponies die from Old Age? Are you Immortal? In our World, Living Badgers die Young, in Mere Years. The Great Lady Eriape had been Working on It, but it was a Difficult Project."

She sighs.

"For Some Creatures, Being Undying is Very Painful, or so I Understand. For us it is Merely Uncomfortable."

"Ponies live about a hundred years. Well, except the Princesses, Celestia and Luna are about a thousand years old. I don't know if they'll eventually die or not." It occurs to her—she hasn't otherwise been prompted to think about it—that Twilight is now going to outlive the rest of them by a long, long time. "... oh no."

"What's the Matter, Miss?"

“Oh, I just realized how sad Twilight will be when all of her friends are gone.”

"She could Make you Undying Too! I have the Spell to make People like Me, though I can't Cast it Yet."

"Twilight might be able to cast it." Twilight is absolutely not going to cast it. (Hopefully.) "Though I'm not sure that would be a good idea, anyway."

"Oh?" She's wandering over to Fluttershy's cottage now.
