"Well, here's your rundown then. For city history, the city was founded a decade ago, by a man named Tektus. The city was to protect those who were fleeing from the Plagues and provide shelter to those who needed it. However, as of now, the Plague still ravages the area near the city. With the protection of our Nanos, we are able to hold them off, and at times, push them back. But with the constant number of the Plague, it seems futile. But either way, we still try to make a living here. Most of the events in the city's history around here usually revolve around either the government, the Plague, or whatever gangs or organizations trying to seize control.
The city is divided into districts. Commercial district, Industrial district, and Residential district are self explanatory. Justice district is for the courts and the police forces. District of Hope refers to the education that those who live here take, since our younger generation are considered the hope of Zayin, though opinion varies. District of Science is usually where we do research of certain topics. Then there are the parts of the city that don't really belong to any district, like the cemetery, the main government building, and a few other minor buildings. Just refer to them as public buildings. You are in the District of Hope, since this is a library for those who learn. It may seem large from my description, but this is a mere city. It's a lot smaller than how grandiose I make it seem."
