A Word About Greenleaf:

https://firefly.fandom.com/wiki/Greenleaf

To add to that, our own Penelope is a native of the jungle.  The term "barefoot" is slang used by the locals to describe themselves.  Through Penelope's memories, we know that there is one large city on Greenleaf around which all the pharmaceutical producers and their supply chains have been built.

One of our passengers, Prof. Marquina, is a botanist who will head into Greenleaf's jungles on the report of a previously uncatalogued orchid.

I'll leave it to Pen to offer up any further local canon she's created.    In some previous offline writing I created a run down saloon, "Hap's La Frontera."  Not sure if this will feature at all in a story beyond Abby picking up a tee shirt, but local color is local color.   

What we can guess is that big pharma means big money.  You know what comes after that.  Have fun!
