Nature

Nature is the totality of phenomena of the physical world and is thought to be the invisible force behind all life that governs the universe. It functions as the source of a witch's power who through the use of witchcraft use spells to manipulate nature.
The Earth is considered to be the physical manifestation of Nature by the witches which constantly provides them with the resources, such as herbs and tools, to neutralize or resolve all types of threats. As a way to channel the power of Nature to witches, the Spirits have control of the world of the dead in order to monitor the actions of the servants.
