Yonuba is a strange sight to behold, and one that holds many unique secrets to be discovered. The entire area is a massive underground jungle below the Sahel Understory, just North of Cameroon, holding many creatures and flora that can only be found in Yonuba alone. Scattered about are cave openings that lead to the above world, and that allow rare glimpses of the sun to reach the jungle below. Despite lacking in sun, the trees and plants that grow are strong, their nutrients coming from the rich soil that is provided by the land and volcanic activity deeper below. High above on the ceiling of the caverns are strange floral growth that cast a brilliant, blue hue across the cave system, providing ambient lighting for those who find themselves exploring the Undergrowth. The climate fluctuates depending on how close one is to one of the many entrances, but for the most part remains humid.

While it may seem like an alchemist's and poacher’s dream, the land is not without it’s protectors. There are tribes hidden about, devoted to protecting the land from abuse. Any who would dare take more than what they need to survive might very well find themselves face to face with the guardians of this land.
