Below are several maps of Ptolus, the geographic region it is in, and an overall view of the Empire. The Ptolus maps will be the more useful ones; the region and empire maps are mostly for reference.

This is the map of the City of Ptolus itself, detailed all the way down to street name. There are two sizes of this map. First is the default medium size version (800kb), or, if you really want a good look there is the large version (3MB).

This map shows the geographic area near the city, known as Eastern Palastan. This might be useful for some information in character backgrounds.

This is an overview map of the Empire, just for reference. One key point to note is that the erstwhile captial of the empire, Tarsis, is far to the east of Ptolus.
