Spread throughout Spirit Island are pockets of deep wilderness, untouched by human hands. A few have a spirit of sanctity about them. The leaves there whisper words of forbiddance, of warnings, of wrath for those who trespass. The Dahan know how to listen, and stay well away. A few spirit-seekers claim that these wild-spirits (powerful as they are) are merely custodians and wardens for other more powerful, spirits of ancient trees and deep roots who wake neither frequently nor easily. Nobody much cares to test the truth of the matter.
