He feels an open summons and lets it grab him -
"I did not. It recently appeared. It is unusual in that it provides only objects to me directly, since its aware life are already adequately eternal."
"So sometimes a world just sidles up to you and is like 'here have some objects'?"
"In the previous seventy-three cases, the world appeared with all of its past objects and aware beings available, and all subsequent destroyed things were similarly available as it proceeded forward in time."
"What does 'available' mean here?"
"An object being available to me means that I am aware of its physical structure and can therefore instantiate it. Or categorize it in a library of items and structures. I personally categorized every structure in the base library of the instantiation interface. Aware beings are more complicated; I can instantiate those as well, but I have automated that process because doing it one by one as they died would be extremely tedious."
"Okay. So previously you've basically been doing Limbo-with-oversight and now you're going to switch to the personal-pocket-dimensions model, cool."
"My domain currently has both more individual convenience and less of my personal attention than that phrase implies, but broadly speaking yes. To be clear, I also intend to leave my current domain and your current afterlife sections more or less just as they are, except for adding transit systems to the sections and interlinking them with the existing transit systems of my domain and the individual transit systems of the personal pocket dimensions. One of the options under 'Miscellaneous' in the interface is a transit station; they are somewhat more rigidly constrained than other structures, because their functional parts cannot be changed."
"Oh, yeah, there's - civilization, in Hell, presumably in Heaven, definitely in Fairyland, it's kind of haphazard in Limbo but it exists, it'd be a pity if it evaporated even if the personal dimensions have advantages."
"Yes. Hmm. Do you have any other suggestions to make before we begin? I suppose it would be convenient to add an information exchange network." A second kiosk appears. "And it should not be necessary for a person to access a transit station in order to return to their personal domain." That change is silent.
"Will the extranet hook up to the one or ones used by live people? Because that would be grand."
"I cannot think of a way to make such a connection that would not be prohibitively tedious."
"Rats. Oh well, one for dead folks will have decent quality stuff on it soon enough - can this interface with conventional computers from various relevant eras?"
"It is possible to transfer information to it from external devices using the intention-based interface."
"Awesome. So, use case, from this pocket dimension here or whatever one I wind up in after the complete system is rolling - I will have my normal powers intact, I will be able to go visit my parents, both parents will acquire probably-fairy powers if they are open to this plan and will have their own little planes, I will be able to email them, I will be able to visit Fairyland and Heaven and Limbo too if I want in addition to Hell, and if I spontaneously undergo a personality transplant and decide to demonically lay waste to Fairyland, the fairies can do... what, about that, since it's not any of their personal turf?"
"Very little. But of course, anything that is destroyed can be recreated in my domain, and most things eventually will."
"So if you do this somebody's gonna lay waste to something sooner or later, there's currently a balance of daeva not screwing with each other's belongings but this will upset it. I would like to visit Fairyland, but not if my ability to do it guarantees that someone else will eventually take it into their head to wreck it."
"How do you propose to solve this problem?"
"Simple version, don't let daeva into each other's domains or Limbo. The pocket dimensions have visiting covered. Alternately, suppress daeva magic while we're visiting, if you can do that. I would have a much harder time laying waste to anything in Fairyland if I only had stuff I could carry and not even teekay while I was there."
"This seems like it would significantly decrease potential convenience as well as potential destruction," she observes. "As an alternate method..." She gets one of her thoughtful looks again. "Go create and then wreck something, and see if the solution I have just provided appeals to you."
He kicks it.
If he has any desires in the direction of restoring the blocks to their un-kicked state, he will see a ghostly preview of the tower as it was when he created it. The preview can be scrolled forward or backward in time, including to times when the blocks did not exist. If he decides to revert to a particular state, the world is edited accordingly, but all previous states remain accessible.
"Huh." Cam reverts to a mid-fall state, watches them fall again, puts them back in an unkicked tower. He vanishes them. He puts them back in a heap. "Everybody would get this?"
"Everyone to their own domains. Everyone of a particular section's type to that section but not the others. No one but me to my domain; I can revert large-scale vandalism myself more quickly than any other inhabitant, and easily ban the vandals at the same time."
"It seems abusable, especially since there's going to be huge influxes of new daeva once the Limboites get the option to promote themselves. The daeva realms are used to one or two new ex-summoners at a time and can absorb us, but this is different."
"Surely any place will reach equilibrium eventually."
