Porn Valley appears as a destination in Spoilsport/Finish Shit, but the name predates the work: it is an established nickname for the San Fernando Valley’s historic adult-film industry. Its use therefore belongs to the wiki’s referential geography, not its inventory of invented Lost Eros districts.
Industrial geography
The phrase behaves simultaneously as district nickname and industry metonym: a real Los Angeles-area production history is compressed into a place-name. In the surrounding passage it sits beside Lost Eros inventions and corruptions, deliberately blurring imported civic reality with the fictionalized geography.
External provenance
“Porn Valley” has long been used for the San Fernando Valley because of its concentration of adult-film production. See Wired’s 2005 account ↗.
