Alicornutopia

Since demons can create plants, simple organisms, and working ecosystems could complicated lifeforms evolve or be bred given enough time?

What is life like for the average Limbo citizen? Are people with valuable objects likely to get them stolen or would someone with a mansion likely to be kicked out? Is there an attempt at equitable sharing of what goods there are?

How does a daeva's memory work? We don't really know what would happen if a human lived for a thousand years, but it seems likely they would eventually lose almost everything from the beginning of their life. Do daeva have a remembered lifespan that is significantly shorter than their actual lifespan? For instance, two daeva who were close friends and then didn't see each other for a hundred thousand years would not know they'd ever met.

But you’d still need an explanation for why nobody’s summoned one of the alternate-mortal-world daeva and noticed, right? I suppose that could be because there are so few summoners in the other mortal worlds that most people go to Very Far Away in Limbo, but it wouldn’t explain about naturally-occurring daeva in the other cluster.

In any case, if that could be made to work, it sounds like an interesting box idea. Fairies (probably the most likely to meet, for a variety of reasons) discover Alternate Mortal World fairies.

Since the average daeva isn't from Earth, and if we assume the Earths are moderately similar, it might not be obvious, especially before Cam revealed summoning to everyone. Y
The demons may be more likely to notice, if say, they summoned contradictory history books, but they'd need to know authors or titles from two different worlds.

Alternatively, each world has it's own group of daeva, and each group feels only it's own world's summonings.

Yeah, there's thriving ecosystems on many hellplanets and parts of the plane of gold and some demons get really into breeding animals or plants.

It is customary in the more civilized parts of Limbo (as opposed to out in random dust spans between clusters of people) that people can have their thing if they are sharing enough. "Enough" is a lot if it's a useful thing. If you have a sink you rig something up to let water run outside your structure, if you have food you give away as much as you can, any renewable resource associated with your thing gets made to renew as often as possible, if you have shelter it gets filled up until adding another person would make it less comfortable than a less crowded mud structure, if you have a vehicle welcome to the postal service or at least siphoning fuel into the postal service's supply at every opportunity. If you don't share "enough" then it is reasonably likely that your thing will be commandeered by others. If you go to uncivilized parts of Limbo or are unlucky enough to land in one (especially with an immobile thing) then stealing is not particularly unlikely. There is some effort by the Limbo postal service to make it harder for thieving or selfish Limboites to get imports from the daeva realms, since those are a limited quantity (even Hell can only export what the train can get through in the duration of the concordance). If you have a mediocre object then you find a town and learn the language pidgin in vogue there and live in a mud structure and try to entertain yourself.

Daeva have at least one memory quirk (summoning-acquired languages are indelible). I am sort of undecided on the extent to which they may have others, but certainly on a day-to-day basis their memories are like human memories.

Thank you!
I'd love to see those hell planets.
You could create so many completely unique creatures. Create a thousand planets, seed them with basic lifeforms, go away and come back in a million years. Travel at light speed for a while if you're worried about getting bored.

Actually, on that note, do demons pursue scientific research? It seems like a good thing to do with eternity, and with that many resources and that little risk there really wouldn't be any limits. They could quickly bypass their earthly counterparts.

Do you know roughly how big the demons' civilization is? One light year across, ten?
Cam seems to reach his home really quickly, but if everyone is making planets around the gold plane there could be problems pretty quickly.

If someone who became a daeva originally had eidetic memory, would they retain it?

Demons get really sciencey! They don't get very collaboratively sciency - they have no strong reasons to - so some of their findings are never shared in an accessible fashion even with other demons, but they do science. Demon engineers are a little more recognition-driven; Cam's computer model is a Hell original.

I don't have the slightest idea how far off you could go from the plane and still find demons.

Cam doesn't live on a planet; he lives in a teeny Little Prince-esque rock with a black hole in it for gravity, not too far outside the pull of the plane. There are a number of such little planetoids in the region and you do have to go farther to find planets, let alone stars.

I don't see a reason to take it away unless they're the kind of eidetic who "runs out of film", in which case I'd have to make a judgment call about whether they'd still do that at some point.

That makes more sense. I was visualizing Cam's home as more moon like.
It seems like there would be some incentive to share, if only to make it easier to get to the next cool thing.

How do demons get their light?
Is it common to create stars or are smaller individual light sources more common?
Is there a central internet like thing for demons?

Is there an upper limit to the size angels can change themselves to be? Could one of them become a big enough a world devouring mythical monster?
On that note, could a demon create a new body, attach it to themselves the way Cam attaches his wings, and then get rid of their original body?

If you go far enough away that you can make a sun and a planet without things crashing into them you may do that, but it's commoner by far to just use local lighting of various sorts.

There is not a standard hellnet. Demons have a really hard time standardizing on things like that. They also have a really hard time allocating radio band by fiat. There are various movements trying to get consensus going to the point where it'll be overwhelmingly appealing to join the club than to convert into your favorite format and social pressure will keep people out of the designated band, but so far no dice.

Angels can get as big as they like, just as Cam could entityify himself in This Is Constant Escalation. Of course, if you're too big to fit in a circle you don't feel its summon.

I'm divided on whether daeva must keep their original brains. They definitely don't need to keep anything besides that though.

Demons can’t even borrow mortal standards when they exist? Even if you can’t get Wi-Fi, I would expect a wired Internet using the mortal IP and Ethernet standards would be able to function with minimal problems. That does require some standardization, but it seems easier.

Do fairies and angels have better standardization practices?

There are small wired networks, just not big cooperative sprawls.

Fairies and angels are much better standardized because most of their stuff is actually manufactured by somebody and some of it's imported from mortals.
