The Greater Chitroit Housing Development, also known as GCHD, the Habs, the Stacks and many other names more vulgar. Just over 3 billion documented humans live in this area alone. The city’s population is closer to 4 billion, when you consider all the 4th shifters, 0-Hours and stowaways. Home sweet home as far as you are considered. The lowest of the low stacks have to deal with the mildew smell from proximity to the bottom of what used to be Lake Michigan. They reached all the way down to the bedrock, taking in all the displaced water and using it. They never quite got it dry down there before the Seal settled into place and it has been damp ever since. From there all you do is go up or go out. Even the lowest window-seat fetches a premium, with the view out over that water it is some of the most desirable housing left on the planet, to say nothing of the beaches. Beneath it is a growing cancer of poverty, relative deprivation and greed, just like any city. The lowest of the stacks, those below the waterline, are sometimes purchased for their adjacency to tunnels or docking stations. Much of the smuggling to and from Outsiders occurs here.
