"Snakes. Long, narrow reptiles, head is mostly mouth. Or mirror, in this case. One of those appeared out of nowhere and swallowed me. Instead of the inside of a snake, I found myself on a planet full of other wildlife with bizarre powers."
"OK, we don't have the same classification system.
Cylindrical, a few feet thick, cold blood, eats smaller animals? Regular eating, usually, not whatever this one did."
"I don't really keep track of the blood temperature of Pokémon. But anyway, I don't know of any Pokémon with mirrors for mouths. Seems like that would make it hard for them to eat."
But if that wasn't a Pokémon, then aside from being even more confusing that apparently means I do need to find a legendary."
"I haven't necessarily memorized all of the hundreds of kinds of Pokémon, so there's also that."
Actually, this is probably a priority, considering how important Pokémon seem to be here."
"I mean, you need at least one to safely leave town - you might be able to manage alone but nonlegendary humans can't - and even if you stay in town there's Pokémon-related stuff everywhere, so, yes, they're important. How much information do you need attached to your list?"
There have to be encyclopedias of this kind of thing, right?"
"Sure, but if you just wanted a list of names or something I could call that up on my Pokétch. Sounds like you want a library. Lucky I know where one of those is too, huh?"
So they depart the clothing boutique and she gets on her flaming horse again and rides same down the street and over a few blocks. Library! It has books!
He finds a book on Pokémon that seems to be searchable by appearance, a shorter book on legendary Pokémon, and a map. And notes the locations of books that might describe the selection of metals on Earth.
Bella finds other books and reads with a Pokémon curled up across her lap being scritched behind the ears.
Turns out the reason emotional Allomancy did nothing to the hat birds was because Murkrow are Dark type and immune to Psychic. He flips through the notes on Pokémon of a similar type, so as to know what to stay away from.
More importantly, there is no Pokémon that looks like the thing that brought him here and none known to do interplanetary travel. Legendaries it is, then.
"You about done?" asks Bella, when he's gone through his books.
That thing that brought me here was definitely not a Pokémon, incidentally. You don't have to doubt your breadth of knowledge."
"Didn't think so. You seem confused enough about Pokémon that I'd be surprised if they existed where you came from. Must be boring."
"We do have some animals, but they're rarely more intimidating than you'd think from their size. And you have much more variety here."
"Hundreds and hundreds. There are songs. I still remember most of the words to the Electric Pokémon Song."
"Just hundreds? We have more, probably at least thousands of species. But not very many matter."
"Then I guess it's arguable if we really have more variety," shrugs Bella. "Anyway. You're going to go legendary hunting?"
"I think I have to, if I'm ever going to get back. I think Sendoff Spring might be a place to start; there's supposed to be an interdimensional portal of some kind."
