One thing he absolutely has not seen is that fucking thing. Giant snake with a mirror for a head. Nonresponsive to attempts to communicate, thrashing about wrecking traffic light and such, and thus: probably Bad News. Bad News which probably calls for murder. Luckily, Ari's good at that.
Planning... perhaps less so.
In retrospect, "punch the obviously supernatural mirror" was not what one might call the best idea.
But there's little enough time to worry about that; he's landed. Ow. What the hell did he land on?
The book on her head glows teal and floats off her head, closing itself neatly and setting itself down on the floor. "You're some kind of beige..." She takes a few steps to the left; the bookshelf on top of him also glows teal before righting itself. "Ape creature."
"Fucked if I know. Uh, I was walking down Fifth on my way to the pawnbroker, there was this... giant snake with a mirror for a face? And, I mean, it was wrecking the intersection, so I decided to get in my recommended daily value of vigilante monster slaying. But punching the mirror, instead of, you know, breaking the mirror, got me sucked through its face into... the library of the school for gifted unicorns. I guess. And I spilled a bunch of books, so, sorry about that?"
"They get along!" she assures him. "My mother is a pegasus and she can do most normal things without trouble. I'd have a problem because I tend to fall over if I'm standing on fewer than three hooves, sometimes even if I try to have one off the ground, but that's just me."
"Well," she starts making a halfhearted attempt at organizing the downed books in auras of teal light, "I can maybe look up some things like that, there might be a handful. What do you do when you've run out of thousand-year monsters? There aren't going to be very many, or there'd be some of them popping up every day from a thousand years ago, which there are not."
"...I might be used to a world with a higher density of horrible monsters, then. Last year I stopped two ancient sealed-off threats within two weeks of each other. And that's discounting vampires, faeries, loups-garou, etcetera etcetera, everything that just eats people for no reason."
"Eh. With seven billion humans, your personal likelihood of getting devoured isn't all that high. As evidenced by the fact that a shocking percentage of them just ignore that the monsters exist. And as to the exhaustion of fighting the monsters, it may be tiring, but long as I know I'm doing the right thing, I'll keep on going."
"That's very admirable. But we don't have as much scope for your talents. I can try to see if there's a way to put you back so fewer of those seven billion people get devoured, but I'm not immediately coming up with a solid research angle so it could take a very long time."
"Hey, I don't actually mind being stuck here a while. I mean, all things considered I'd rather not be trapped for the rest of my life, and saving people's great, but this place in general sounds like a tidy vacation spot, you know? And if I happen to clear out a few prophesied apocalypses while I'm in town, I'm still helping out the adorable ponyfolk."
"Like I said, we don't know which direction the causality goes, so it's possible that your foal would grow up to match the name, but it's also possible that you would wind up feeling inspired to name your foal something less... that... in slightly clairvoyant anticipation of its talents and interests."
"Well, I don't actually know how old you are, but most humans who look like me aren't fifty, so your guess was probably pretty reasonable. Unless you're, like, ten. Wizards live for hundreds of years; humans live about ninety, in ideal conditions. We wizards kind of get all the nice stuff, really."
"Souls! It's like, uh, a little bundle of energy some species have that means they're not controlled by one specific purpose, like making shoes or drowning lost children. Without a soul, who you are matters less than what you are. Doesn't mean soulless species aren't people, though. And I'm pretty sure you have a soul, for what it's worth."
"Easiest way is through a soulgaze - if a wizard looks into the eyes of someone with a soul for more than a couple of seconds, they simultaneously go on this very vague symbolic vision-questy thing through each other's souls and understand things about who the other is. But you can't, like, see their thoughts or something."
"I've never personally tried it, but I'm pretty sure we don't have the stomach acid for any kind of grass that hasn't been processed into flour. Things we eat... Meat is big, but I'm guessing ponies don't have a lot of that. We can eat fruit, corn, spinach, bugs- lots of stuff. Might be easier for me to look at a menu and rule stuff out."
Outside are lots of pastel ponies. Unicorns and pegasi and earth ponies. Ari gets a lot of weird looks, but since he isn't doing anything threatening and is accompanied by a totally normal pony, no one gives them any trouble.
Ari grins irrepressibly in response to any and all weird looks he receives. (What does he care if he looks kind of weird? He's the beige ape here.)
He picks out a spinach pie and some variety of fruit tart, then turns to Clarity. "Do you guys have any kind of barter system, or should you pay and I pay you back when I have money, or what? I've got a handful of assorted gemstones, but those usually aren't currency, and I think they're probably worth a bit more than a café lunch."
"Yeah. If I'm hurting somebody, it's bad unless they're doing bad stuff; if somebody else is hurting somebody, it's bad and I should make them stop unless the people they're hurting are doing bad stuff. And various extra rules in that theme. But I never really got around to the little finicky stuff. There was usually bad stuff to stop."
"There is a minor subtlety that even if the target of hurting is doing bad stuff that should be in some way relevant to the hurting - if somepony's kicking other ponies for no reason this is not justification for stealing their possessions - but yeah, that'll probably do for most purposes."
