Haria sticks get nose out, then, bit by bit, she emerges fully, and shakes off the dirt. "Gosh that is a Lot of Area of Effect,  Not that its Not Appreciated! What is the Circle and How long will that Last?"

“It should last until regular nightfall, but I think I can figure out something better by the next sunrise.” If they decide to let Harià keep existing, that is. “What’s a ‘circle’?—I mean, I know what a circle is but I don’t think that’s what you mean.”

Fluttershy is still kind of stunned.

“… you can do that?”

“Shh, don’t tell anyone. I wasn’t actually sure I could do it until I did.”

"Where I come from Spells have Differing Topological Genus. Higher Genus usually means More Powerful, and we call the Genus of the Spell its Circle. I can cast Third so I am Third."

"Oh, we have that. The most powerful spell I can cast is a six but that, uh, wasn't a spell, it's something I can only do because I'm a Princess of Equestria. Princess Celestia raises the sun over all of Equestria every morning but I'm not that powerful."

An Important Pony. "It is Very Impressive Nevertheless. Are you Able to Trade Spells? I like Extradimensional Effects and also Flying."

“Maybe later.” If they don’t decide to kill her. “But right now I need to go talk to Princess Celestia. Also, I don’t need a spell to fly.” She spreads her wings.

"Okay!"

Haria wanders over to investigate the edge of the effect, then returns to Fluttershy.

"She is Very Powerful."

"Oh, yes, she is. Princess Celestia taught her herself."

"Do you need anything? What do Undying Badgers eat?" Hopefully the answer is not 'ponies'.

"We don't Have to Eat, but I will not Turn Down a Fresh Mole. I do not Formally Need to Drink or Breathe Either and this is Very Useful for Undersea Adventures! There are Many Advantages to Being Undying!"

She looks at Fluttershy.

"What do you Eat?"

"Oh, a lot of different things, but mostly plants. Sometimes milk or eggs, but we never eat meat. There are other creatures in Equestria that do, though.”

"I like Eggs Too. A Fresh Axebeak Egg is Quite the Feast!"

"What...is an axebeak?"

"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."
