Phantoms are rather rare but populous species of creatures almost always found flying in the night skies with a watchful gaze. However, recently, a strange humanoid variant of phantoms have been observed to start populating the wilderness. The humanoid phantom species are usually shy, but their behavior varies from area to area, some hostile, some shy, but usually territorial. If you happen to encounter a phantom in the wild, back away and it will leave you alone too.
