Estreoth/Energy

Energy in Estreoth is a complicated subject relating to various forms of supernatural energy. Technically speaking, the term energy refers to a metaphysical force that is separate from the scientific understanding of energy such as mechanical or chemical energy. As the inhabitants of Estreoth have no concept of electricity or chemical reactions, in common usage, energy refers to this concept.

Properties
Although there is little serious study into the basis of energy itself, the properties of it have been studies by a handful of scholars. These properties include wavelength, density, and force.

Forms of Energy
Energy is usually categorized by its origin into three forms, spiritual, natural, and magical.

Spiritual
Spiritual energy, sometimes called personal energy, is energy that is created by individual beings. All sentient beings possess this energy in varying amounts. Spiritual energy is the easiest of energy types to sense and can be freely utilized by an individual. However this form of energy is rather limited as relatively few individuals have the spiritual output to utilize this energy. In addition, this energy is extremely difficult to transmute into other forms. Despite this, a skilled user of spiritual energy is extremely potent, capable of enhancing their body's physical abilities since, unlike magical energy or nature energy, the human body naturally utilizes spiritual energy. One of the largest limitations of this form of energy is the user has a finite amount of it that can be used at one time.

This form of energy can also be called Qi, Chi, Ki, and Chakra.

Natural
Nature Energy, also called Life Energy, is the ambient energy given off by plants and simple life forms. Natural energy is slightly more difficult to use than spiritual energy, and cannot be used to enhance the physical body in the same manner. It can however, be transmuted into elemental forms. However, the amount of ambient natural energy varies depending on the environment. Lush fertile jungles are rich with natural energy, while deserts contain only traces.

Shamans are often associated with natural energy, however some advanced spirit users utilize this energy as well.

Magical
Magical energy, also referred to as planetary energy, is the primary energy source in Estreoth. Emanating from within the planet, magical energy is the only form of energy that most humans cannot directly manipulated without a medium and quite difficult to sense unless its highly concentrated. Despite the requirements to utilize this energy, magical energy is extremely versatile and can easily be transmuted into elemental forms of energy. This utilitarian nature of magical energy combined with its natural abundance makes it an extremely useful resource.

This energy rises up through ley nodes and flows beneath the planets crust over ley lines. Near the nodes and the lines, magical energy is notably more powerful than the average concentration.
