Neutral-ish Planes:
Arcadia: Lawful (Systematic instead of just Organized) with Good tendencies (Giving instead of completely Selfless)
Those who care primarily for
Conformity and Tradition, secondarily about Benevolence and Security
A meticulously planned, mathematically precise world of harmony and community for people who believe in sacrificing freedom for the legitimate Greater Good for all people, as opposed to an imaginary "Greater Good" for justifying cruelty, who truly understand that the system exists to benefit the people as opposed to the other way around, but who go too far in regulating too much of each other's lives based on too comprehensive a definition of "Evil," not always being able to distinguish between truly "dangerous" and merely "different."
They would certainly not want to threaten "undesirables" with violence, for fear of creating a true tyranny where anybody could be victimized next, but they don't see why those different from themselves would not want to either become "better" - adapting themselves to a system that allegedly works better when everybody is the same as each other - or to go someplace else to form their own society where both groups can be out of each other's way.
These are still basically good people, and benevolence and morality are still important to them, it's just that control and appearances are even more important.
In life these legalists gave more time and energy to challenging the potential evil of disorder and disobedience than to building the definitive good of all people regardless of differences. So too in death do they stay in a "perfected" community to take care of each other far from anybody considered "excessively" different from themselves.
Ysgard: Chaotic (Disruptive instead of just Independent) with Good tendencies (Giving instead of completely Selfless)
Those who care primarily about
Self-direction, secondarily about Universalism and Stimulation
The battlefield of those who care too much about the victims of oppression, and who risk too much antagonizing bullies, to qualify as Chaotic Neutral (who challenge the powerful primarily for the sake of their friends and families, rather than strangers, and won't go so far as to put their personal safety in danger unless their loved ones are already in danger), but who get too excited about the resulting conflict and spend too much time and energy on it to qualify as perfectly Good (who - even at their most Chaotic - use conflict only as a tool against further oppression, rather than as an end in of itself, and wish that it was completely unnecessary).
These are the people who don't leave an injured person near a hornet's nest because "why should he forced me to risk myself when the hornets aren't doing anything yet" like a Chaotic Neutral (or worse, kicking the nest at the person if they would get away with it like a Chaotic Evil), they kick the hornet's nest away from the person so that even when they get angry, he is still keeping them away from the other person by making them go through him first. Now, a truly Good person's first thought would be to carry the injured person out of harm's way before doing anything to the nest specifically that could make things worse, but the fact that putting himself in harm's way to protect another was truly important to him still counts for something, even if the way he went about it was more important to him.
These are still basically good people, and helping the little guy is still important to them, it's just that fighting the big guy is even more important.
In life these rabble-rousers gave too much more to challenging the potential evil of order and oppression than to building the definitive good of the innocent people who needed more help rather than less harm. So too in death are they thrown into the greatest boxing ring in the universe, where billions and billions of like-minded competitors can beat each other senseless with whatever brutal, nasty weapons they can come up with specifically because nobody's actually getting hurt in this realm of violence without victims.
Mechanus: Lawful (Systematic instead of just Organized) Neutral (Normal, average)
Those who care primarily about
Conformity, Tradition, and Security, secondarily about Benevolence and Power
A clockwork world of those who felt that everybody owed their complete obedience and loyalty to a bureaucratic system that ensured only their basic survival in return - while fully thriving would require that they work even harder than that - and expected them to be thankful for the privilege, as allegedly the system invented people for it's own betterment as opposed to the other way around.
In life they cared only for predictability and obedience over common decency and human empathy. So too in death do they become mechanical constructs in a world where everybody else is as thoughtless towards them as they had been in life towards everybody else.
Limbo: Chaotic (Disruptive instead of just Independent) Neutral (Normal, Average)
Those who care primarily about
Stimulation and Self-direction, secondarily about Universalism and Hedonism
An artistic, exuberant madhouse molded by those who spent their lives concerned mostly about their own freedom to explore new and exciting activities, who valued true creativity over baser pleasures, who didn't want to be forced to help others but still didn't want anyone to get hurt except in self-defense, and who made sure that everybody knew that they wouldn't be repressed without a fight.
In life they wanted mostly to live in their own little worlds, reciprocating the care they got from others and resisting any attempt to be controlled. So too in death are they given an infinite space based entirely around creating absolutely anything they want with whomever they want, co-operating with people who agree with them about what would be the coolest thing to make or do and having infinite space to stay out of the way of people who disagree too strongly to stay friendly.
Acheron:Lawful (Systematic instead of just Organized) with Evil tendencies (Selfish instead of completely Destructive)
Those who care primarily about
Security, secondarily about Conformity, Tradition, and Power
The plane that started all of this in the first place.
Endless fields of battle fought by those who herded the desperate masses in life for personal benefit, building powerful institutions so that they could exploit the "resource" that is basic human life and labor.
This is not the "reward" of continuing a life of waging war for it's own sake, as those who care primarily about the destruction and violence over loyalty to a cause are probably going to Gehenna or the Gray Waste: they are not truly, Systematically Lawful as they did not want the conflict - however well structured and organized in of itself - to ultimately be made into anything, such as a tyranny where those on top will eventually not have to worry about conflict against rebellions.
Thus, favoring Systematic exploitation over pure Destruction, Acheron is for completely different people: those who had spent their lives working to build something incredibly useful to themselves, yet all but useless to those who served the machine out of desperation. The warriors and generals who go here are not the ones who waged war for the sake of waging war, but
rather the ones who focused exclusively on how to make themselves benefit if they are already drawn into a war.
In life, these industrialists and politicians cared for their legion of minions only enough to ensure that they themselves still had a system to support themselves. So too in death are they driven by remote commanding officers whose victories are meaningless to those who have become the minions, just as their own victories in life had been meaningless to their own minions.
Pandemonium: Chaotic (Disruptive instead of just Independent) with Evil tendencies (Selfish instead of completely Destructive)
Those who care primarily about
Hedonism and Stimulation, secondarily about Self-direction and Achievement.
A network of caves pulverized by gale-force winds that toss and fling eternally those who had spent their lives consumed by - and drawing others into - the tempests of their own appetites for novel experiences and substances, never wanting to work for anything not part of one of their "games" and constantly trying to persuade those around them to become equally thoughtless towards the future of the real world in the name of more intense "games."
