"Industry, old school values, and a lot of shortcuts. Whatever the cost." — Rockstar's official description
Ambrosia is Leonida's heartland: the rural-industrial belt around Lake Leonida, dominated by its sugar refinery and the working culture that grew around it. Rockstar's inspiration points to Florida's real lake-country sugar belt.
Rockstar's official tagline says it all — industry and old-school values on the surface, shortcuts underneath, whatever the cost. Official materials tie biker culture to the region: small-town Americana with an outlaw streak running through it.
Rockstar's description of Ambrosia is blunt: "American industry and old-school values still reign supreme — whatever the cost." The Allied Crystal sugar refinery provides the legitimate jobs, while the local biker gang — the Final Chapter — provides almost everything else. It's the economic and criminal engine of Leonida's industrial heartland.
