I've been thinking that, with all these ghosts, perhaps ethereal plane buildings will be found all over the city, and the burghs of Ether are just more specific, highly built-up ones that are hubs of ghost activity.

On the matter of population density, let's not forget the presence of the Shadow Plane and how many of the inhabitants live there, too, both in and out of Shadowgate or whatever we named that district.

I think the concept of demographic shift, instead of clear boundaries, is important in a city like Ishka. The districts themselves have clear political boundaries, but I don't think even specific racial districts like Ungul or Gulliver's Heights are totally homogeneous. You can find goblins throughout the city, and in Gobin (and remember, not all the goblins are necessarily from the same goblin culture in Gobin- they could be from other material planes, even). You could find four-legged creatures outside of Ungul.

I think this paradigm in thought should be kept with regards to the separation of home and work. Remember that even with Ishka's public transportation networks, getting from one district to another is a big deal. The whole concept of bedroom communities is really a product of the rise of the middle class in post-industrial western capitalist societies. Usually, in most of history, people live near or at where they work.

In regards to the 'lives' of ghosts, I am tempted to look to the campaign setting, Manifest, for inspiration on how ghosts may spend their days and nights. Remember that they don't require sleep. I suppose some of the best scholars at the University would be ghosts.

I think the ghost gambling should work like mutual credit, not like currency. You start with no points, and having no points is average. Having points is good. Having negative points is bad.

Hmm.... now ya'll are tempting me to go ahead and make a campaign in this city. I've already got two campaigns running, but the socialist revolutionary campaign I made in Sharn went south because all my players were moderates who didn't know what socialism meant, assumed I wanted them to be anarchists, and then grievously misunderstood what anarchism was, eventually becoming insane terrorists. So, now, I have another possible group starting up with players who not only understand anarchism and socialism, but *are* anarchists, communists, and socialists. I may have to start a campaign here with them, maybe as Collective or Wild members, and post a fiction based on it.
