I've been considering formally introducing the trees commonly found in my forest. It is what the natives call "Klouskops", growing to an average size of 50 feet in height and a diameter of 6 feet with many branches coming off of it, creating something of a black web expanding all over the forest. The leaves that grow off of the klouskops are black, hence the evolution of Night-Walker skin coloration. One vital aspect to these trees that have become very important to the Walkers is that the branches, especially the thicker ones, are quite sturdy. They are able to support the basic huts that Walkers live in (normally one of these basic structures can be built on the thicker branches in the villages). The leaves and branches often leave the most wooded areas with little sunlight, and thus have developed a form of photosynthesis using the top of the tree as a "collector", delivering the necessary materials down to the rest of the tree.

Here is a picture that shows off (sort of, I'm not great at finding pictures) roughly what they would look like-

What are your thoughts? Would they be feasible for the "Homelands" inhabited by the Night-Walkers?
