"We just have humans."

"Are they okay? Our humans were not so well off before they met Quendi but the Enemy had been making it worse."

"Uh, we are having a nothingness problem but we're... fine?"

"You are out of things to turn into nothing for magic?"

"Not quite - it's complicated. But if it doesn't stop it's gonna eat the world."

"Oh dear. Is this an unavoidable feature of your magic or something specific to your society's use -"

"If it's avoidable we don't know how. It took a while to get this bad. A while and a war."

"Ah. Should we hesitate then to deploy your magic in our war, even if we can, or are there precautions -"

"Uh, you don't want to overdo it, but a small amount would take millennia to eat a world or even a really inconvenient fraction of one."

" - well, dooming the world in a few millennia won't do either."

"It might give you long enough to find somewhere else to live?"

"Lot of people wouldn't go. I suppose if we can't find a better way we might have no choice."

"Yeah, sorry, I did not come equipped for a rescue mission."

"We aren't losing the war. Just - better to plan for the worst."

"Yeah."

"Do you know anything about the distribution of worlds? How many, do they have different magic each time..."

"I wasn't even sure there were any, I put my affairs in order before I magicked myself away from mine. This is promising though!"

"It really is!!! What do you need to do it again -"

"Uh, from here I can't monitor how much worldeating is accelerating back home, so I'm reluctant to do any magic while attached to my current - dump site for nothingness - except very sparingly to the point where it's noise against how much magic other people are doing. I can make a new one but then there will be one here and I won't be able to attach myself to my home world or a new one in a third world without physically going there, which requires doing magic. Apart from that I need fresh blood and fine ash - do you have baths here, by the way - and some other miscellany."

"We have baths. Once there's a dump site will it keep growing on its own, or only when you do magic?"

"We used to think the latter. Turns out probably the former, but if I do only a little and no one else is sharing the site it could be a long time before you could notice the difference."

"A long time for humans is not a long time for Elves."

"Then you will want to use my magic even more sparingly than I."

"More matter can't be produced to replace what gets - eaten?"

"...that would help a lot but not completely solve the problem, and my magic can't do that."
