...sheeeee's bored already. Are the people hanging out in Lorien talking about anything interesting?
Eventually she dozes off.
She has breakfast (turns out there is no random plant that ought to taste like scrambled eggs but there's a kind of tree bark that can do decently at toast and she likes cantaloupe-inspired berries!) and then goes to the courtyard.
"Hi," she says. "I made these fruits taste like chocolate for you but I don't know if it lasts when they leave the forest."
She pours them into his hands and goes and has a look at his writing progress.
The symbols are not concepts - it cannot be that this one represents a horse, this one a person - because they repeat too much; you would never tell a story that way. They could be sounds. He says a few sentences aloud, tries to imagine how you'd draw the sounds. The symbols repeat about as often as a sound might be repeated, spoken aloud. There are about as many varieties of symbol as sound. Yes, that's it.
Now to figure out which symbol is which sound.
He is thinking about something interesting and so does not notice the door open.
Awwwwwwwwwwwww this is the best and cutest self-insert fanfic everrrrrrrrr.
"You might be able to make some progress if you had illustrations in the books," she says, "but it would be extremely hard. How's the fruit?"
"He might have been able to figure out which concepts the words corresponded to, with enough books, but I don't think there's any way to get the sounds, not without knowing in general which sounds there are in languages and which sound clusters are common and even then that'd only get you a guess." He eats the fruit. "Oooh. Tastes - well, I suppose like chocolate."
"It's a weird texture for chocolate - I can get stuff there to taste like anything but the mouthfeel's all wrong for half the foods I've ever eaten. You could find a linguistics book with diagrams of how people hold their mouths to make sounds."
"I shall have to write one." He looks crestfallen. "There are so many things I shall have to write. I pleaded with Rúmil to get his eyes fixed so he could help me - I can't be his eyes for something as precise as writing while I'm writing something different myself - but he just said maybe when there were better options."
"...I'm going to try to reinvent arcane healing. It'll be a long while though, arcane magic doesn't take to it as well as divine."
"The Valar could do it. I think he's being slow because people are worried about -" he scowls at the limitations of his Pax - reembodying everyone who was taken prisoner by Melkor and he likes going around as a visual reminder that you can be a perfectly delightful contributing happy Elf even afterwards.
Bella repeats that in Pax for him. "Well, he does do that, and very well."
