Although the followers of the Church of Wisdom prioritize knowledge over everything, they are not the type of people that will ignore the benefits of living amongst natural objects.
As such, most of the residential areas on the Church of Wisdom's territory were abound with trees and other kinds of vegetation, with the majority present at the commoner's section.
With the protection by the Church of Wisdom and its residents, the amount of the trees that can be seen in this area is so great, that one can actually call it a forest. And this forest continued to grow because of the rules laid down by the Church of Wisdom.
The Church of Wisdom itself stipulated that nobody has the right to indiscriminately destroy or tear down the forestry in their territory. At most, one can only obtain their needs from the forest if it was legal and acceptable in any ways.
