Essence manipulation

This worlds magic

essence comes in two forms: light and dark/void. one of the most vital laws of essence is that essence will always try to untangle itself in time.

Light

Light essence is a physical essence it is often visible when in use and the usability of it can be from creating fire to wounding spells to create barriers.

void

void essence is a much more psychological essence it is not often visible but one can feel it. This is commonly used for: Making people go into a trance to hide things in shadows to transfer ones soul into another creature

Arcane/ poly magic

however a third usage of essence was discovered that used both light and void essence to draw upon the raw energy that came from in-between the two poles. this is referred to as the arcane.
One of the biggest differences from pure essence manipulation or mono magic is that spells created by this form of magic can last for centuries as opposed to the pure essence that is often dispelled once the user stops channelling.

but where does essence come from?

essence is in everything that is living and dead. living creatures has a great amount of both light essence and void essence. however plants and of course sunlight is made up of mostly light essence. bones of creatures and shadows hold the most void essence. The amount of essence in oasis has not always been this high. it was only until the celestial war when the celestials drained their homelands for its essence that it became this prevalent.

Who can use magic?

For someone to learn to channel they must first build something up that is called a core by channelling tiny amounts of essence. A core sort of a reservoir of what essence you use in time the core will dislike being so hollow and produce its own essence. This leads to the body growing more resilient to said essence. ones core cannot harm their holder unless the core does a jump from small amount of essence to huge amount of essence. this can lead to the affliction that is shattering death or madness.
Magic can shape the user into biologically creating a core over time. this means that if a parent practiced magic their child will can be born with a strong core and be able to use larger amounts of magic without practice. a core can not be manipulated or changed. if one is born with a core that is the core they have. it does not change ever. The most powerful mages have unbalanced core creating a huge amount of essence to them. they might have a dark core or a bright core depending on how it is balanced. in some rare cases ones core can be so unbalanced that the user creates more essence than they can use. these people are called Vidore . another anomaly is the core of the user is that it is always hollow and never creates essence. these users have to draw upon essence around them for every little spell. these users are called leeches

Manifestation

light essence manipulation in a large scale can take the form of a bright yellow flame or as a beam of the same colour.
void essence manipulation is not visible unless in huge amounts. it will then take the form of a black cloud.
arcane manipulation has the manifestation of a bright yellow light weaved in with dark purple clouds. in some cases just a purple and yellow opaque crystal/ light. some skilled illusionists are able to manipulate the light essence to make it have whatever colour they want.

Elements

depending on an area or a creature is all well and good but is has become a bit outdated. a newer way of casting spells is to simply have an object bound with either light or void essence. some objects are easier to bind to a certain essence than others.
some usual void elements are: small daggers, bones and skulls, religious symbols
some usual light elements are: plants and herbs, religious symbols
It is common for skilled mages to either have a plethora of elements or elements and a familiar creature.
Elements will loose their power over time. they dont last for ever.

Iron

Iron negates the usage of essence. However it does not repel essence. It simply hinders the casters ability to cast spells if it touches them.
