The DFW metroplex is the second most influential sprawl in the CAS, second only to Atlanta. The population of the city swelled tremendously following the invasion by Aztlan in 2035, mostly with Houston refugees, but also with a sizable number of Aztlan immigrants. The city was already on the edge of breakdown, but the influx of refugees pushed the services of the city to the breaking point. It is only within the past 15 or 20 years that DFW has managed to get a handle on its problems and emerge as a cultural and economic powerhouse in the CAS.
