Jalizar rhymes with Shadizar and Lankhmar.... This book begins with a long description of the city's history and some of its features. A wonderful city map is provided too. The rest of the book is magnificient. As always, there are character concepts - I just regret that some of these concepts are not included in the stats section with "Denizens", but this seems to have been partly corrected with the document "Archetypes of the Dominions and Jalizar" that you can download for free.
The "sidebars" are excellent inputs, ex :Thieves' Signs, Merchants of Jalizar...
After new edges, hindrances and trappings, the Setting Rules will help Gamemasters to enliven the rotten atmosphere of Jalizar with game mechanisms for beggars, thieves and all ingredients for dwellers of that urban jungle. There are random generators for urban locations, citizens, traps, beggars' features, and sewers (with are described in depth).
Of course, other RpG systems have longer fantasy guides for cities, but U. Pignatelli has understood that the main task for urban gaming is not about having a city map for tourists, rather about situations and atmosphere. Sometimes, Jalizar (though it has its own personality) makes me think at the corrupted city of Kharé, in the "Sorcery" gamebook series by S.Jackson. Umberto has made Jalizar, the Flower of the North, "so rotten that it is good..." for roleplaying ! Definitely a must-have for any game session taking place in a medieval fantasy city.
