Drevoz are the chosen species of Numilla. Believed to be one of the first chosen species, Drevoz do not seem to have a single point of origin and reside in every forest in the world.
Drevoz are the most diverse of the chosen species. All Drevoz physically resemble trees with limbs, but vary in size and shape depending on the type of tree. Some are only a few centimeters tall, while others tower over 100 meters. Drevoz are born from a seed planeted by the parents, and are indistinguishable from a tree to anyone but a Drevoz until they reach maturity.
Most Drevoz live their entire lives as gardeners of their forest, maintaining the delicate balance of nature and protecting the forest from threats. Drevoz rarely leave their home forest, and those that do start suffering from an illness known as sumabolest within a few months. They experience symptoms such as depression, grief, unexplained pain, and even death if left untreated. Returning to the home forest is the only known cure, though spending time in any forest among other Drevoz can ease the symptoms for a time.
