“The Byzantine Bank” is a rules-free description of a place that might be found in many different sorts of communities and cultures and was written as a specific example of a Pawnshop, one of the more than 85 places described in the Skirmisher Publishing book City Builder: A Guide to Designing Communities, a comprehensive, fully-illustrated manual designed to help storytellers create exciting and compelling urban areas and other sorts of communities.

“The Byzantine Bank” is intended to stand by itself or serve as bonus content to that volume and appears in the Swords of Kos Fantasy Campaign Setting. 

Both this example and City Builder overall are intended to be compatible with the needs of almost any ancient, Dark Ages, Middle Ages, Renaissance, fantasy, or other role-playing milieu. .
