From the back of the book:
Introducing the City of Ptolus, district by district!
This book offers a chapter on the first four of the city’s eleven districts. But first, the City by the Spire overview chapter provides information that applies to every district or to the city as a whole. Here, you’ll find information about Ptolus’ races, its climate, layout, economy, and much more. This overview also details the Commissar and City Council, the City Watch, and other official institutions. Following this overview, you will find details on these individual districts: the seamy Docks, the bustling Guildsman District, the adventurers’ favorite Midtown, and the deadly Necropolis.
This is one in a series of nine Ptolus PDF releases from Malhavoc Press. When used together, they comprise the entirety of the Ptolus print book. Each one is also usable on its own for city-based
fantasy d20 roleplaying campaigns.
