Pocalo Infrastructure: Elevators
The tiered structure of Pocalo makes travel from one province to the next a challenge, unless you can hop on an elevator. Large elevators, like the one pictured here, are designed to carry a great deal of freight and several passengers (it seats around 150 people, so about the same as a medium-sized commercial airplane) among multiple provinces.
This particular elevator services four levels, and does much of the heavy lifting (ha ha) for getting agricultural foodstuffs distributed to the northern regions of the provinces. Merchants also use this elevator to move their wares around, perhaps selling medicines in one province, picking up some local foods, and moving on to sell those in a different province.
There are much smaller elevators dotted throughout the provinces, generally just ferrying between two levels. Most of these are concentrated in the upper provinces; the lower provinces (i.e., those at ground level and below) have relatively few elevators. This has more to do with population density than anything else; large swaths of the lowest two provinces are flooded, rendering them mostly uninhabitable.
While elevators have connected the provinces for around 300 years, this type of large freight elevator is relatively new technology (maybe 100 years old), and has accelerated cultural exchange and homogenization. While the people of each province still have their own distinct accents, clothing styles, foods, and so forth, basic necessities are widely distributed wherever you go.
Anyone can engage in political satire in Pocalo, but *THE* Satirists are special elected officials whose commentary is seen as especially insightful and funny. Their essays are published in a periodical called So Say the Satirists, which is made freely available to all residents of Pocalo.
Pocali culture doesn’t assign any specific societal roles or presentations or clothing to you based on whatever body parts you happen to have been born with, or whatever body parts you happen to have right at this moment. People dress how they want, perform the work that best suits them, and adopt whatever mannerisms feel comfortable to them.

Shriekers are one of the largest predators in the Valley. They are typically found where forests meet open space, and typically prey on herd animals of various sorts.
The names humans have for many of the flora and fauna of the Valley come from Rovari, the Daraz language (Daraz are native to the Valley, humans are not). This particular creature is called merev gombi in Rovari, which literally means “hard sphere.” Humans usually just call this animal “merev.” 
Millenia ago, the people of the Valley domesticated an animal known as a cloud spider*. Spider silk is exceptionally lightweight and has extremely high tensile strength, and the humans have been able to tease many uses out of an animal that yields a large quantity of silk. 
Ah, the humble blue beetle, such a common sight in the Valley it gets the most obvious possible name. It’s also one of the main sources of animal protein for the citizens of Pocalo. So delicious, so nutritious.
