They seem a little confused by her asking that. "Imports" in an Achamite sense are just the tithes they take from other cities, which are a flat rate, or on demand. Most imports are food or luxury goods. As far as they knew, none of the other cities had tried to avoid paying their tithes for quite some time. They will explain their take on this to her, that none of them would dare to defy the Regent even before this.

As for maps, they do have them! Is she looking for a world map or a city map?
