What is the difference between Cities of Hârn and Son of Cities?
Son of Cities was originally published as an extension to the Cities of Hârn book. It contained additional pages which could be added to the end of the seven city articles in Cities of Hârn, mostly additional details of specific buildings. Later, the Cities of Hârn and Son of Cities books were sold together under the name Cities of Hârn. The Cities of Hârn material is undergoing revision and expansion (possibly doubling in size), but the publication format and dates have not been set.
