Lifeforce

A Lifeforce is the energy that an organism has that allows it to exist in a physical way. Separate from the Soul, which is seen as its own entity, the Lifeforce can be given and taken away at will by certain able-bodied individuals.
==Characteristics==
What makes one's Lifeforce unique is more difficult to identify than appearance for example. In most cases, the Lifeforce is unique within the genetic code of its inhabiting organism. Often possessing the enhanced properties or abilities of that organism.
A good example of this would be the Mages. As each Mage has a different set of abilities, taking away their Lifeforce would also bring along with it said abilities. This occurred twice during the Overwars, one when Lazarus drained and absorbed Stolas's Lifeforce, and again when Ankhor willingly gave up the rest of her Lifeforce to Drasilia.
===Appearance===
While never being directly observed, several instances of seeing a Lifeforce give it the impression of a warm, yellow glow. In some transferences, the Lifeforce will appear flowing through the organism's veins. Sometimes a centralized, glowing circle will move around the inside of the body.
===Lifeforce-Soul distinction===
While the Soul is more of a supernatural and spiritual way of imagining oneself, the Lifeforce is a more grounded and scientific way of doing so. For example, ghosts are beings that can live without a Soul, due to said Soul moving onto the Afterlife. Without a Lifeforce, there is no energy or spark that allows life to exist within an organism.
==Tangibility==
As said earlier, certain devices or certain beings have the capability of giving or taking away a Lifeforce. The capability of doing so often exists within the Lifeforce itself or through extensive training that would require genetic engineering.
However, the ability to willingly surrender one's Lifeforce to another is embedded within every organism. Usually only depending on whether or not said organism has awareness of the ability.
===Transference===
Often a way to transfer a Lifeforce has been with maintained physical contact. For example, Ankhor kissing Drasilia, allowing for Ankhor's Lifeforce to enter Drasilia with enough space, suggesting that a Lifeforce is a physical object that takes up space.
===Effects of Lifeforce draining===
If the Lifeforce of an organism is drained from its home body, said body will cease to exist as a living thing. The color of the organism will slowly fade as the pigments in the skin or cells die off. Leaving the organism completely devoid of color.
