Near Grey Hollow Village, the origin point of the color consuming virus, life intermingles. Infected by the Saturophage very near the beginning, the intricate hybridization of genetic accelerationism is in full bloom in the Cos Fringes. Skeletons of mighty structures dominate the land, becoming shelter and sustenance for the local inhabitants. Though not the seat of power, many influential beings claim the fringes as their home - an important crossroads for the forest.
Ecologically this region serves as a buffer zone, a place where the ancient traditions of the forest dwellers meet the innovations of the more technologically advanced societies. Rituals and ceremonies conducted in the fringes often symbolize the harmony and conflict between these two worlds.
