Lighthalzen is the largest city in the Schwartzvald Republic, boasting an over populated fifty thousand or so people of varying races. It is divided into high- and middle-class residential areas to the west, business and shopping districts running north and south of the city, and run-down slums to the east. The vast city is also known as a booming research centre with a major pharmaceutical companies, Rekenber Corp., having their headquarters here; though it is known that pharmaceuticals isn't all they produce.
Due to the availability of medicines in Lighthalzen, a major hospital complete with intensive care units, quarantine sectors and laboratories is located here. The Schwartzvald Republic's military headquarters also is in the city, receiving weapons via airship from Einbroch weekly.
Due to the large population of the city, there are high taxes imposed upon the residents for the upkeep of the metropolis; this makes it very expensive to live in. The exception to this is the slums, where many people live in rented homes for lower prices thanks to a few landlords that have bought out the area. But outside of the slums, most of the residents of Lighthalzen are of upper-middle class or just downright wealthy.
