Cam conjures up some Heaven and Fairyland news, since he can read it in Milliways, and concludes: The increase in demand is doing most of it, but some indirectly - they no longer pounce on summons when they might want one soon, they expect to be able to get one anytime and wait till they feel like it. Surveyors think more people are taking summonses but average payout's improved so they don't have to show up to six of them to get what they want.

Think we should alternate which summoning-capable worlds have time passing in them, or anything like that? I don't think we should add another...

Yeah don't add one till demand from dots levels off and can be more addressed by retrieving locals. Wait time on randoms is not catastrophic, but maybe find some daeva who are keen to be individually summoned a lot for some higher effort payout? Take dot summonses all day for twelve languages and a Puffskein and five doses Polyjuice plus a tipoff about how fun Elf hair is?

He'll conduct interviews. 

He will try to help with the summoning demand problem! By taking summonses, that is.

Plenty of Godspring, some Ardas, some Revelation.

And back to Milliways he goes. "Next concordance is Fairyland and coming up, right? If we can get something from Limbo out then the flat Arda Valar can portal in..."

"How recently from Fairyland would it have to be, Hell has some indestructible curiosities from before trains were invented... they'd be unpopular to take but not hard to look at."

"No idea."

"Well, that'd be the thing to know."

"What would?" asks Karen, heading in to collect breakfast from Bar. "...Hi, Minor."

" - hi. How recently from a world something needs to be for the Valar to portal to it. So we can go to Limbo."

"Oh. Cool."

Nod. "How have you been."

"I'm fine."

" - okay."

...breakfast. Breakfast is fascinating.

Okay. He leaves Ambela a note asking how recently of a place the Valar need a thing to be.

And Ambela inquires.

...they're not sure, sorry.

Well, there is a Limbo imported harp known to be in such and such a place if they want to go look at it.

They go look at it; can't get a portal.

There's a Fairyland concordance soon but they will need to go alongside a very fast train designed to take up all of the space in the concordance.

They can be immaterial, that should not interfere with very fast train. Also that's an impressive work of engineering on the Limboites side to have a concordance-length of fast-moving train's worth of tracks, how did they build them?

The daeva worlds ferried them materials during pre-train concordances.
