"I know, right?"

"Did you ever look into anything related to that or just idle musings?"

"...haven't been in a position to do independent research for a while."

"...right, erm, sorry."

"But! Now we both are in such a position and we're going to revolutionise sorcery with science."

"You sound very sure of this."

"Well as far as I've been able to determine no one has actually done this kind of thing systematically, and sorcery seems to have consistent rules, so it's the kind of thing that will probably eventually crack."

"Fair enough."

"Not to mention the fact that I'm incredibly self-confident and also confident in you."

Now, where are those fairies that wanted to do science with her?

Here they are!

"Hello!" she greets 'em.

"Hello!" some of the fairies say back.

"Leeeet's do some science," she says, and tries opening a gate to get signal.

Conveniently, it's an instant settle.

Cool! So the first thing she tries is looking up some cipher that someone certainly has used in the past. The most obvious one, it turns out, is a Caesar cipher, moving letters a fixed number of steps ahead or behind. Since this doesn't tend to produce pronounceable words, she has to write the order 'wave' in paper: xbwf.

Nobody waves. They can't understand it.

What if she tells them in advance what it is and how it was gotten from another word and what it means?

(She doesn't expect this to work, and if it does that's an entirely new feature of plain speak.)

They will have to take her word for it that this is a meaningful connection of some kind between the word "wave" and meaningless scribble but that doesn't make them able to read it.

Okay, so just naively using ciphers doesn't work even if they were the very first ciphers invented. ...can they read Al Bhed at all or does 'fyja' also come off as meaningless scribble?

Meaningless scribble!

Hmmm... Atbash cipher? That one even has a cool name! She'll try writing a word in Hebrew (google google) and then writing the same thing with the cipher applied to it.

Fairies cannot read that either.

But they can read the thing in original non-ciphered Hebrew?

Sure! They can barely tell the difference between that and English, really, although Promise notices that it's being written the other direction.
