A description of a moderately large city, this supplement has 19 pages of text, and a further 10 pages of maps, plus the floorplan of a guardhouse. Six of the maps are of the city as a whole - with numbered labels, text labels, and no labels, each in colour and black-and-white. The remaining four are expanded versions of the main maps, each showing a quarter of the city, in larger size for printing, but without extra detail.
The city itself seems suited to a high fantasy world, due primarily to the vast scale of the architecture. The governor's palace, for instance, is ten stories high, and the city walls tower 300' (higher than the spires of many medieval cathedrals, in the real world). All of which is perfectly reasonable for a high fantasy setting - and the walls, in particular, are implied to partly magical in construction - but not, perhaps, for more low fantasy campaigns.
Having said that, a few tweaks to the descriptions is all you'd really need to change it. Beyond the architecture (which is atmospherically described) the basic concept of the city is that is largely ruled by three noble families that don't entirely get on, and that it is built on the ruins of a much older city, dedicated to the forces of evil before its eventual destruction. Unfortunately, not a lot is made of the latter point, it's more of a plot hook than something that is really explored in the supplement.
There are full page stat blocks of the heads of the three noble houses, the governor, the commander of the city guard, and the high priest of the main temple. All, except maybe the priest, seem surprisingly low level for the size of the city. (The population isn't given, but we know the guard force is 250-strong, so it's surprising that the guy in charge of it is only 4th level). But they are at least well thought out and distinctive.
A number of locations, including all the shops along one street, are given brief descriptions, which can add flavour to the setting. There are also discussions on some unusual local flora, a mildly narcotic drink (no worse than alcohol, really), and some unique architectural materials, as well as things like the sewers and the water supply. Again, some of this implies a high fantasy setting, but nothing too far out of the ordinary.
There is also a page of scenario ideas, some of which would work in any city, and some of which are more specifically tailored to this one.
All in all, not bad if you're looking for a fair sized, but not huge, city to put down in a fantasy campaign. The setting it is part of seems fairly generic, so there should be little difficulty in applying to most campaigns. The maps are reasonable, and the layout and proof-reading are both good. It doesn't, perhaps, have a true 'wow' factor, but it's quite good of its type.
