"Um, the closest thing that comes to mind is a spell called 'atonement', which I don't remember a lot about and it's divine magic. It wouldn't do free will outright, I think - I'm not sure there's anything on my plane that lacks it to start out - but it might work on an oath." (She has been thinking about this for reasons.) "It's very fuzzy divine stuff but the popular conception is that the caster can discharge somebody's mistake onto themselves and then it's easier to clear, it's more of an energy cost than anything else."

"That would have tremendous implications, were it possible here and if it had any effect on words spoken before Eru."

"I'm not sure if it would. I might try to invent an arcane version if I can get enough of the pieces figured out but it'd be very risky to play with and might not intersect with the right kind of thing at all."

"Are you not trying to reinvent divine magic? Or is that just the next project?"

"I don't know any of it to start out, and the resident divinities are a lot different and don't ultimately run on divine magic," she says. "There's some cross-domain applicability between arcane and divine, so I'll have a better idea of whether I'll ever get to the point of being able to figure it out in a few years. Well, figure it out without resorting to planar shifting the applied theology section of a library from my plane into my house."

"The prince Curufinwë was under the impression fetching books from your world was very dangerous."

"Going and getting them would be. I think staying firmly in Valinor and just sort of summoning books would be okay. Well, in terms of antagonizing the universe; it would be stealing. I'd probably want to do it with a Vala looking over my shoulder just to be really sure but my plane hasn't done a single thing to me or anybody else since I've been here."

"The Valar would be very interested in the things you're describing and I imagine delighted to help. ..is there precedent for your plane interfering in other ones?"

"Um, resurrection spells do that - dead people go to one of several afterlife planes. And an overlapping set of planes produce summonable animals, which have some combat use so of course that's the thing everyone summons. And I think there's a thaumaturgical debate about whether, like, fire spells are just generating fire or if they're summoning it from the Elemental Plane of Fire? 'Summon Library Stack' would be new but not conceptually unprecedented."

"And what landed you here? Do you know?"

"I think it was sort of the opposite of a summoning spell, but it may have been done incorrectly or something and I'm not sure what they would have been trying to send if I hadn't stumbled into it."

"Certainly something we'd have been less advantaged to have dropped on us."

"I wasn't gonna say it."

He laughs, stretches his arms in a motion that's almost humanlike. "I imagine we could have managed it. Melkor had allies in all kinds of forms in the last war. Our fortune in getting you has almost nothing to do with what they could have sent through instead. Though if it'd landed in the palace with the baby prince that might have caused problems."

"I might have heard about it if a reverse summoning spell - as opposed to a planar travel spell - were being used on people in my school. They probably just would have sent you a rabbit or something."

"What's the relevant distinction between reverse summoning and planar travel? And perhaps they sent us many rabbits. We might not have noticed."

"You might've noticed one in the palace! Planar travel is you cast it and now you're on another plane; reverse summoning is you cast it and now something else is on another plane."

"Ah. Both arcane magic, so you can eventually learn them?"

"Presumably. Scrying first though."

"Scrying is one I expect to be in high demand, so people can check on their loved ones who declined the invitation to Valinor."

"Intraplanar scrying should be easier than interplanar."

"Scrying before transport will probably cause a great deal of grief, if people watch others in danger and desire to immediately fly to the rescue."

"...Maybe first I'll get long-distance messaging spells."

"That would be one solution. What are your ambitions here, Bella? I know some people who would delight in reinventing everything but you seem likelier to desire that as a means to some end."

"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."
