Probably the single biggest reason Pocalo is a cultural melting pot and a destination worth traveling the world to get to: their medical science is unparalleled.
People come to the Valley to seek cures for their own ailments, or to buy medicines to sell elsewhere in the global market, or to study the practice of medicine. No surprise, then, that researching and cultivating medicinal flora is a big industry.
Pocalo is home to a huge number of microclimates, which in turns means there are countless rare plants that only grow in specific (and sometimes dangerous or hard-to-reach) places.
Botanists are always looking for species that can be domesticated and grown on demand to reduce production costs. Places like the Pharmaceutical Research Center in Uttara City typically have greenhouses that cultivate whatever useful species can be grown in the area. The modular nature of the building helps prevent unwanted cross-pollination of the plants being cultivated, or escape by potentially invasive species.
The Research Center forms the economic hub of the area, and specializes in plants found locally. The plants and medicines produced by the Research Center are traded to other regions in Pocalo, who in turn trade their own plants and medicinals to Uttara. This network of pharmaceutical centers across Pocalo defines the layout of intercity and interprovince trade routes.
Pharmaceutical scientists like Amihan, Beneke, and Rosse study newly-found species in hopes of discovering new medicines. Of course, not all species can be domesticated or cultivated, so runners like Chadsen go out to find them in the wild.
