Ambrosia sits in the heart of Leonida and is described in Rockstar's own material as the battleground for the state's health and wealth, built around old school American industry rather than tourism. Its centerpiece, the Allied Crystal sugar refinery, echoes the real sugar industry long operating around Florida's Lake Okeechobee region. Rockstar's description frames Ambrosia as a company town at heart, the refinery providing the jobs while a local biker gang, per the official material, provides almost everything else. That split between legitimate industry and organised crime running in parallel is the clearest signal Rockstar has given about the area's character. Beyond that framing, no specific missions or story content tied to Ambrosia have been confirmed. The description and the biker gang connection come from Rockstar's own material rather than a leaked source.
