The San Fernando Valley (locally known as "The Valley") is an urbanized valley located in the Los Angeles metropolitan area of southern California, defined by the mountains of the Transverse Ranges circling it. Home to 1.76 million people, it lies north of the larger and more populous Los Angeles Basin. Nearly two-thirds of the Valley's land area is part of the City of Los Angeles.
Before The Change, the San Fernando Valley held over a million people. After, the Dieoff occurred killing about ninety-eight percent of the population leaving about twenty to thirty thousand survivors. At first, survival came from scavenging abandoned buildings and planting garden plots. Chatsworth to the north west had been horse country with amateur breeders raising horses. Bruce Delgado organized the Chatsworth Lancers, a cavalry unit, which conquered neighboring communities such as West Hills, Canoga Park, Reseda, Woodland Hills and Northridge making them vassal states. This left Chatsworth dominating the west end of The Valley.
It did allow for better organization with parks being planted, vineyards started along with orchards and reclamation of parking lots by breaking up the asphalt for crop fields. It also allowed Chatsworth to control salvaging, preventing outsiders from pillaging usable goods even thirty years later. However, Delgado was still interested expanding south through Topanga Canyon to the Pacific.
By the late 20th century, the valley north and west of the central city of New Liverpool was still largely rural, but more homes and business districts had arisen. The people of the valley had a clannish streak, making it unsurprising that the Independence Party would have a base there.
The Valley was one of the few Big Uglies-inspired place names that made sense to Straha, an émigré of the Race who had settled in Los Angeles. The name told what the place was, without any obfuscation or elaboration.
