I'm currently planning of creating a demiplane-city which would serve as a cosmopolitan hub like Sigil, called Nexus. Basically, it would be a huge megacity with population larger then Sigil's but just as diverse. But I'll need your feedback and your help, because I'm a bit of an idea's man, but I need some help to make sound better. Plus I've never done anything like this before.
Here are some ideas of what I'm planning to do.
Layout:
Nexus would look like a regular Prime city, but it would only be larger, sort of the size of a small country/state. How many kilomeaters/miles do you think it would have to be. And what would the population be like this city, I mean how big. Also the Nexus would be home a diverse population, not only from the Prime but also from the rest of the multiverse, so many of the buildings and districts would be diverse. In sense, if any of you have the Urban Arcana book (or browsed at it like I have) then it's like a normal UA (magic-exists) campagin, where bugbears rule the streets and dragons rule the corperate boardrooms, but on a larger scale.
Also, could you please give me some detailed info on the types of districts/regions that a large city might have and what races/creatures would be commonly found in them.
Government:
I was thinking that Nexus would be run by centralised Civic Departments, each one playing a different role like Law, Economany, Health, Defence ect. Any more ideas?
Then at the top would be council of demigods, each one being of different alignment (good,evil,law,chaos ect). How many of them sould there be and what roles could they perform in everyday life besides decision making.
Laws:
There would be the regular laws for both mundane and magical crimes, but the greatest law would be pro-tolrance laws, because as a cosmopolitan hub, Nexus would have a lot of different races living in it. With that in mind, it's important for most races to co-exist (most of the time), so hate crimes are strictly punished with either fines, a certain amount of time in jail or even death. Certain Factions like the Harmonium and Redeemers would help out as well.
Also fiends and races like the Slaadi would also be expected NOT to kill/eat/torture innocent people or animals, but they will be given a certain amount of rights if they do so. If not, they will be harshly punished. And I do mean harshly.
Religion:
A number of gods will be worshiped in Nexus, but most of good and neutral alignment. However, evil gods will a some presanse, with hiddin temples/shrines and a smattering of differnt cults, but they are few in number. Also worship of the demigod rulers of Nexus would be very common.
Trading and commerce:
As the name implies, Nexus is a great hub in the multiverse (which gives them a sort of rivelry with Sigil) and it trades not only with the a large number of Prime worlds, but also with the upper and lower planes and the rest of the multiverse. So much trading happens in a single day that most wearhouses are wearhouses of holding and that it is often said that so much economical transaction in a single day is enough to buy entire nations.
Protection:
The powers of the demigod council dose do some help in the protection of Nexus, but that alone isn't enough. Alternativly several powerful good and neutral align gods would offer their protection as dose several powerful Factions. Also Nexus would have an interplaner treaty with several Planes to help them out. And finally, Nexus would pay the 'loths with money or goods to keep the armies of Baator and the Abyss off their door step. Also all the portals of Nexus are watched over by portal-gods, who do a good job (most of the time).
Life in the Big City:
As stated above, Nexus is a diverse and complex city, filled with diverse and complex races. Gnomes can find work as technicans and mechanics, elves vist the parks on a weekly basis, goblins squat in abandoned subway lines and gang wars between fiends are common in the poorer regions. The city also has it's dangers, such as zombies attacking the living, evil wizards scheming and roaches the size of ponies eating matnince work in the subway. All in a typical day.
Let me know what you all think!
Some leading questions - why are these demigods working together? Who are they?
