Yay! And under what licenses do these people care to offer the songs?

Someone wants to control all copies; someone is fine with a copy-for-copy deal; someone is fine with her giving it to anyone who isn't with the Feanorian host.

...will the first person at least let her have a loop of it running in her personal song entourage for use, or do they just want a favor?

Yes, that's fine, she can keep it for herself, just not hand out copies.

And that third person, are they budging?

No work of his is keeping that host comfortable at night.

There are murmurs of potential interest, but nothing else specific, and it's late in the evening.

She's not sleeping. If everybody else is sleeping, she'll sit up doing spellwork. She doesn't accelerate herself; no data on prolonged exposure yet and she doesn't have another task to break it up with overnight.

Findekáno, who is also not sleeping, stops by occasionally to watch her at work. He doesn't say anything.

"No," he says with a sigh. "We are temporarily safe and fed and there is no more construction this site can benefit from and we've scouted for appropriate locations to settle once everyone has recovered and is in good health again and there's nothing on my mind, which is a shame because I think I was doing better when there was. Any ideas for projects?"

"Nothing comes particularly to mind; I have lots to do but I can't so much delegate it. What do you usually do to fill time when you're insomniac and nothing's pressing?"

"The ones from Macalaurë are about what I would have ordered up, although I could stand for them to have fewer side effects. I assume if anyone could teleport this would have been a substantial game-changer long before I arrived to tell anyone about potential destinations. Same with anything of particularly spectacular combat value; I was told that songs invented in Valinor tend not to have that as a focus."

"There seemed rather little need. I don't think teleportation is the sort of thing our style of magic does, it's all very local in effects. I think people are working now on things to make arrows fly straighter, make one move faster, that sort of thing."

"Physical speed could be handy too in case I ever have to kill multiple Balrogs at once or something. I suggested magic artillery at the other camp, don't know if the suggestion landed."

"At a guess, it did. Though if they didn't already have it in the works I'd be surprised. I imagine Fëanáro started listing ideas the minute he saw that Angband has walls."

"Sounds about right. ...A spell that gave me retroactive eidetic memory would, uh, override my discomfort with mind magic. Dunno if it's possible. But I've read so many books -"

"...I could try. Not inherently outside the scope of our magic, though sounds very difficult."

"I could, there are so many - I've read books on nuclear physics, I'm sure you'd have a hell of a tense while after the fact if I had to involve Fëanor and I probably would but I could remember enough with that to teach him to build the wipe-Angband-off-the-map thing, I've read the books I just don't remember enough -"

"You know, I actually think that having weapons that could wipe Angband off the map would make him easier to deal with. He lashes out when he's hurt, not when he's strong. It's why I'm more comfortable with the realization they're positioned to learn so fast and so much."

"Great. So all we have to do is make him the sole nuclear power on the planet and all will be well."

"I didn't say that."

"Having lots of those things around is a recipe for everybody setting theirs up to automatically retaliate if they are wiped off the map so nobody twitches first. Sometimes somebody twitches."
