On Monday, a rest and then some portal-hopping via Ciel leads you into the heart of Manhattan. The city is clearly suffering from a lack of constant upkeep. Signs of flooding are everywhere, most of the buildings have been thoroughly looted, and several landmark buildings from your version of New York are missing, having simply never been built.
There are sections, though, that are well-kept and even well-secured. A fly-by reveals several small areas that look like claimed territory, complete with growing gardens.
The northern section of the Financial District is alight with electricity and activity. Buildings there have been turned into places of pleasure, brothels and casinos and bars, pit fights of every kind, drug dens and markets.
At its center is City Hall and the nearby Woolworth building. The small park in front of City Hall has been converted to an auctioneer's block and a handful of holding pens crowded with slaves and surrounded by watchtowers.
