"So! Backround information first: My world, which is called Suaal, has dramatically more variation in personal power than, so far as I can tell, Har does. In Har, what magic people can do is based on what magic they were born with and how well they understand how to use it. …you know that, you live here. In Suaal, magic varies dramatically in strength, and there are a small number of very very strong people called gods. Gods are, instead of being born to parents or built by designers, are made of quintessence, which is concepts-given-substance, including concepts like 'agriculture' and 'good tools' and 'overthrowing governments' and such. And then the gods build lesser beings out of quintessence and other materials that share their values, and the gods and their allies go around making the world more like their values which gives them more power. Except actually, it turns out if a bunch of disagreeing gods do too much of that, then the world breaks, so most of them they made agreements and now they mostly don't go around changing the world in person and have limits on what the people they make can do, too."
"There are some coalitions of gods. One coalition is based around Law: like the Hari Empire, they want the people they have power over to know what the law is. They want to have peaceful negotiations instead of value-destroying violent conflicts. The notable members of this coalition are Hell, Axis, and Heaven. The other major coalition is based on … Hari is the Language of the Empire gave me fewer words for this. Friendship, wanting to help everyone, wanting people to not be miserable, et cetera. This coalition is the Celestials, sometimes known as the Upper Planes. Members of it include Heaven and Elysium, but a lot of the Celestials aren't part of either."
"I don't think you want to work with the non-Heaven Celestials much, they'd respect your laws about slavery less than Heaven would. However, if you do want to work with them, I like them just fine and would have no objections to this. …okay, I actually do have an objection to you working directly with Elysium, I'd strongly encourage you to put up signage saying 'Hari children have powerful magic and if you free them from slavery they can be very destructive very quickly' or similar before doing so. But that's tangential."
"Anyway, of the Lawful powers, Hell would like to enslave and torture pretty much everyone and is very good at misleading contracts, even when they set things up so you not them get to write the contract they can still twist it to their favor. Axis shares your desire to have the law reflect the results of the violent conflicts that would happen so as to make those conflicts pointless, but in Suaal, that principle doesn't point to democracy, and so to appease the rather powerful god of Death, Axis enforces laws requiring everyone who isn't a god or some other exceptions to die eventually. Heaven is the only major Lawful power who actually wants the people of Har to do well."
