"Axis is the Lawful Neutral afterlife. Physically, there are patches of any environment that someone wanted enough to arrange, but our cities are particularly popular. Being morally Neutral means that we are happy to interact with people no matter their values, not that we are required to maintain some sort of balance, although a few people like that do exist. Our most famous god is Abadar, god of commerce and mutual benefit. You can buy almost anything you might wish for, including Good and Evil things, and Chaotic things too. You can sell just about any skills or items you have to offer.
Abadar is not our only god. We have many concerned with various forms of order and honor, or concerned with other things entirely while pursuing Their goals Lawfully. Markets are not our only form of interaction, although they are the most common. We accept anyone who is safe and reliable, whatever their habits and manner, including not interacting with others at all.
Many souls choose to buy improvements, eventually taking many forms, with myself as a one example. Some, valuing self-sufficiency, prefer to develop strength and refinement by themselves.
I will now respond to Nirvana, and, preemptively, to what I expect the other advocates to claim. Nirvana is a place of great charity. Axis does not, as a plane, especially value charity, but we are prosperous and life is bountiful.
Nirvana offers growth only in a particular direction, with limited variation in form and abilities. While Axis cannot match the fluidity of the Chaotic planes, we are, to repeat, prosperous. Almost any enhancement you want can be bought, and, more concretely, a very large selection of well-liked options is available for prices that most can afford. I said earlier that you can buy almost anything you might wish for, and there too, I can say more concretely that almost all of the things that people want, weighted by frequency, they can obtain after a time that they think is reasonable. On average, 98% of a person's lasting unique desires are fulfilled after a time they think is reasonable.
Despite my clarification, you can probably think of more tricks in those statements, but tricks are not our way, usually, and if they are, the possibility is announced. Hell uses tricks without warning. The Evil planes are generally unpleasant. If you want to fight for Good, the Good planes will use you more efficiently than Axis, and similarly with Evil, but Axis is more able to accommodate any other goals, if you are capable of being sorted Lawful."
