Energy

**Energy** was a property of the universe which could be transferred from one object to another through various means. It was also possible for energy to exist in a pure form known as **flux**.

## Description

All things in existence possessed energy in some form or another. It could be present in a number of possible forms:

### Potential

Any object with mass, as well as some massless objects, possessed an intrinsic amount of energy due to their relation to other objects or their surroundings. This energy could generally be considered to be stored 'in relation' or 'in tension', and was capable of enacting change on the object depending on its mode of storage of energy. Displacement of the object or release of tension required an input of energy to destabilise its equilibrium and transfer its potential energy into other forms of energy. This would be done proportional to the nature and strength of its aforementioned relation or tension before settling at a new energetic equilibrium.

### Kinetic

Movement was the most well-understood form of energy transfer, and was a manifestation of kinetic energy expenditure. An object could travel up to a speed proportional to the energy used to accelerate it, and then maintain the kinetic energy until it encountered an obstacle, in which case it would transfer the kinetic energy into the object. Varying amounts of energy would then either be stored as potential energy in the obstacle, transferred as further kinetic energy to the object if it could be put in motion; or dispersed as thermal energy.

### Thermal

Heat was an expression of thermal energy as it pertained to the transfer of energy between systems. It was considered to be a transfer of energy across a temperature gradient by means of disorganised motion. In some ways, this disorganised motion across a gradient could be viewed as an expression of kinetic energy transfer. However, it was important to distinguish that the individual transfers of organised kinetic energy between particles was a poor representation for the transfer of energy by thermal means (an average of disorganised energy transfers).

### Planar

Each plane of existence could have been considered to be an ordered form of planar energy. This energy acted as a barrier for potential, kinetic, and thermal energy, through which it could not readily pass. It was capable of sequestering these forms of energy into discrete planes, while allowing for enormous flexibility and elasticity. These properties allowed planar energy to act as a barrier between classical energy systems, but also be manipulated to allow those energies to transfer between systems.

Planar energy was also present in seemingly infinite quantities as *planar flux* in the Cradle of Existence. The primordial of order, Oros, was the source of all planar energy.

### Entropic

As an inverse of classical energies, entropic energy was conceptually an *energy void* capable of influencing objects within the sphere of existence in near identical ways to other forms of energy. It was a dominant form of 'energy' which superseded other kinds of energies present in the same space. As it permeated the entirety of the planes , entropic energy was capable of subverting well-understood energetic behaviours throughout the universe.

Outside of the sphere of existence, the endless void known as the Great Unknown was a conceptual 'space' comprised entirely of *entropic flux*. The primordial of chaos, Aeth'yr, was the source of all entropic energy.

### Vital

All phenomenon as they related to the processes of living beings such as life and death, consciousness, sleep, dreaming, and spirit, were driven by the transfer of vital energies. This form of energy appeared later than the other fundamental energies of the universe, and had a profound impact on how they interacted. Vital energy, similar to entropic energy, superseded other kinds of energy, albeit only under certain circumstances. It behaved in a similar manner to potential energy, in that it was capable of enacting change upon its surroundings proportional to its relation to them. Vital energies, however, could not be actively transferred to a system which did not already possess an amount of vital energy.

Pockets of vital magic were rare in the universe, but would typically cluster as such due to self-attracting behaviour. The primordial vitae, Vilias and Arymath, were the source of all vital energy. Though they coexisted within the Geminian Host, Vilias was directly responsible for the elements of vital magic regarding the life cycle, while Arymath was responsible for its psychospiritual elements.
