Insect wings can't bear human weight. (Even bird and bat wings is kind of pushing it but I'm willing to declare them to work.)

Heaven may or may not contain wars, it has not been established. There's probably subcultures into it *somewhere*.

Daeva aren't immune to mind magic in full generality, but they will heal from structural brain damage and cannot be affected by things that must travel through space and go beneath their skin in any way when so doing. Kiribel could read them, say. I don't know what in particular you want me to say about witchcraft and runecasting.

I was vaguely assuming some sort of research, or that the bird and bat wings got help from secondary powers (not sure how angels would do it, demons could just create wind)

Well, comparing with Hell (Little gain, but little loss from war) and Fairyland (bigger gain, but bigger loss from war) it seems heaven would be most pacific worlds... urgh, it could go either way, it certainly doesn't sound like the wars would last long.

I was generally curious about exceptions to Daeva indestructibility and possible ways to deal/contain/change them, like using a spell to freeze them solid or something.

[Alicorn]

You could not freeze a daeva themselves, but you could encase one in a block of ice and they've have to deal with that (this wouldn't be particularly hard).

While Fairyland fauna-flora might not have evolved, and certainly didn't evolved from Earth's life, does it look like "Alternate Earth evolution"-ish? Would they survive outside on Earth? would Earth-life survive there if introduced in the enviroment with weird food sources?

Fairyland has a pretty Earthy range of climate and other life-relevant features, so I don't see any reason transplants in either direction shouldn't work. This has probably even happened. Summon a fairy, offer to trade them a kitten and a cactus for a this and a that, resummon them at a later date to perform the swap.

I still cant help but think "Minecraft with different fauna-flora", if only I knew how to create mods.

God, this sounds like a great way to troll a biologist.

I assume Summoning doesn't bring diseases/virus? This sounds like a disaster waiting to happen.

[Alicorn]

Daeva are not subject to diseases, and Fairyland flora and fauna are not subject to the same diseases as Earth species, so no, this isn't an issue unless a demon tries biological warfare or something.

This is actually about 25 billion times as much energy as one kilogram of matter-antimatter explosion; I'm not sure if that means my calculations are wrong or my intuition that the matter-antimatter explosion must be bigger is wrong.

Mh. I thought so too at first, but: Consider that in an uranium nucleus there's about 0.4% of it's mass the coulomb potential of the stuff. Now if you have your 1kg of free iron nuclei they would need much more energy to be compressed into that shape. This energy would still be in that stuff and become something 25 billion times denser than iron. Not quite at black hole levels, but I guess a ton could do it. Or one gram if you left out the space the electrons took. Then I guess we had the paradox of a charged black hole. Gravity wouldn't be able to compress the iron nuclei, but it would try to compress the electrical field. Even though the electrical force is greater than gravity, they still wouldn't be able to escape the black hole, because space would be so bent out of shape that there isn't a continuous path between the inside and the outside. So now you have an object with, at a meter of distance, a thousand times earth's gravity acting on the neutrons, but at the same time violently repels protons, eliminating all other nuclei and sucking in half a gram of electrons. The Missing electrons would propagate as a "Wavefront" across all nearby matter, disintegrating it. Well, I guess you have just invented the Little Doctor.

All this is of course just playing around as we would achieve unification of forces long before amassing that much charge. The weak force would play a big role in such a highly energetic environment that could easily create it's heavy bosons, maybe it even unifies with gravity, need some sleep before figuring that out.

Most of that was over my understanding of physics. I was able to see some of that and think “oh, yeah, that’s a thing I know about, but I have no clue how it works”; I wasn’t sure for other things. I was just modeling it as a collection of classical particles (protons and neutrons) or a single charged sphere (because they’re small enough that you can pretend continuity), with the “about 1 kg of iron nucleii” meaning “a number of iron nucleii equal to the number of atoms in 1 kg of iron”. I wasn’t accounting for mass being partially (completely? I don’t know; this sentence is about the limit of my understanding of the subject) binding energy.

[thebutcher]

Well, antimatter is the most efficient because it releases energy from twice it's own mass, by destroying matter of the thing you want to attack. If you have one kilogram of antimatter and put it into a target of matter you gain 2 kilogram of energy, because you're using some of the enemy's energy.
Your idea would be conjuring one kilogram of iron nuclei plus 25 billion kilogram of pure energy. But because Demons don't have a mass limit it would still work.

tl;drMost of that energy would then transform into matter and antimatter, explode and only then re-annihilate. It's like when you try to pull apart a proton you need so much energy that it will turn into a meson and a new proton. In fact, the strong electrical field will rip apart all the protons AND neutrons repeatedly and turn all the pure energy into mesons... Which would all be monoflavor pions, thus decay nearly immediately and completely into two photons of 67.488MeV. So you would get a small amount of fast particles(which you want) and a cosmic amount of extremely hard radiation(yeah... it's mainly anti-personnel) Angels could transform a kilogram of stuff into, preferably, a tiny amount of electrons and about a kilogram of pure energy for the same effect.

One problem is that the electrical force would be stronger than the nuclear force. It would be even more dangerous and hard to use than antimatter. What you get would be ridiculous amounts of EXTREMELY hard radiation. There would still be an explosion, but it would be omnidirectional laser-like gamma-rays killing everything.

The used matter would turn into the radioactivest of all radioactive stuffs. Use a nuke, it's better for the environment.
