When Fëanáro is feeling sociable she hangs out with him. He finishes his novel. (In it, the school turns him over to social workers and adopt him out, he escapes his foster family, he encounters a dragon and talks his way past it with stories about Arda, he studies wizardry and is unreasonably effective at it, when the dragon opens a portal to Arda he sneaks through too and the Valar slay the dragon, he fixes his mother with magic, and then he masters planar travel himself and conquers Bella's plane.) He finishes his typewriter, too; Bella's of the opinion that it would have been easier if he made vowels separate instead of consonant-hats, but it works okay like so. She acquires one when there is more than one, and learns to type, because crystal balls are a long time coming.
She has made some progress, though. She finds the common thread in dud combinations that produced an aura, and successfully decomposes all her original spells into pieces and begins to make new combinations. Most of these are trivial like the increased character limit arcane mark. Reverse-engineering her undead-damaging spell, though, gets her (small) arcane healing well in advance of when she was expecting to have that down. So anybody who lives on her block and cuts themselves cooking breakfast can knock on her door - or that of anybody who's getting the spells as she turns them out - and get that seen to without bothering a Maia.
Once a month she sees Miriel. Bella doesn't have any ideas that land any better than "forget you forgot something". But forgetting the contents of that foolish, foolish oath is at least a holding pattern that lets Miriel pretty much live her life, so, therapeutic success? ...Bella makes sure to remind Fëanáro that he is very adorable and lovable and adored and loved.
"It's nice here but it could be more convenient, and in the long term there's other places that aren't as nice that could use evacuation or reformation or something. The rest of this plane, and other ones."
"Some of the Eldar didn't agree to come here. I'm not sure how they'd feel if we went and spruced up their homeland. I know even less about the peoples of distant lands. I am sure there are some who'd want to first ask Eru's counsel, too, though -" he waves a hand - "we might not be interpreting Eru correctly, if I do say so myself."
"Well, Valinor in a general sense, not necessarily in any specific aesthetic or politics or layout or anything. If there's somebody who objects to arbitrary plants being edible or the eventual availability of launderers or not having to keep everybody you know within arm's reach all the time lest something eat them I'd love to hear their arguments."
"CanI send you research notes occasionally? I would like to work on figuring out whether your magic has access to some kind of interpreter that allows it to do the same things we're doing with much less precise control, and if the answer is that it does, and we know the fundamental results that we're trying to achieve, your project would be one of understanding the function of the interpreter and possibly how it was created. I do not particularly expect this to work, but I think it's worth examining."
"Um, I'll look at the notes, sure, although based on that description I'm not particularly optimistic..."
"...Maybe everybody is. Which would be a heck of an exploit, since in my home plane science isn't allowed and we've been doing a lot of science to magic."
"My universe has a lot of power structures that don't form a sensible hierarchy with each other. 'The universe' is what we call the thing that prohibits science, and it does it by, well, being the universe - it can make science unrewarding at best and counterproductive or lethal at worst. Here, it's not the universe and doesn't have being the universe privileges; but wizardry might run on something else that doesn't answer directly to the universe, at least outside its jurisdiction."
"We are eventually going to pardon Melkor, in exchange for his aid on a task no other could attempt, and the immediate aftermath of that attempt is unknown to us because mercy and a second chance cannot be granted with full knowledge. Many Years after that new lights will rise above Arda and new races will be born to it, and they will war, but through tragedy and horror some of the Elves will meet them and aid them, as will I, and eventually they will multiply and fill the whole world save Valinor, and have great and terrible kings and build great and terrible things."
"Melkor's pardon is inevitable unless you happen to find the means to break oaths; the problem that only he can fix is that there are people sworn to him who have orders right now to do harm, and he can resolve it by telling them they are free to go live their lives, and we must attempt to aid them. Melkor's pardon may be for the good anyway; we can pledge ourselves to better courses. The arrival of Men is not for three hundred Years. That seems enough time for you to be quite a disruptive force."
