Each Race, person and living thing has an aura demons,devils,angels,elves,trolls, dwarfs, dragons, and humans and dragons
Each calls their aura something different. Not everyone will have the same aura, even if they're related. Most families will have similar auras, but each has its own distinct presence. Hence, it's kind of easy to detect people or specific people.
It'll be harder to detect people or find specific people if they are adept at changing or disguising their auras.
Auras types and explanations of Aura pools
Auras can be destructive, creative , elemental, defensive, or controlling.
People can have up to three types of auras though that's mostly done by extreme training and so far is only found to be done by faction leaders.
Most can naturally have 1 or 2 but you can learn to get from one to two.
Either through natural aging or through training that is difficult but not as hard to accomplish as trying to add a third aura to your self.
For example, Kaiser he's born from demons so naturally he'll have a naturally easier pull towards destructive aura which is the most common among demons, despite this he actually has a natural affinity for a controlling aura, there are cases where demons aren't just immediately born into destructive aura they can even have an easier time with other aura types
Kaiser, having trained when younger, has access to two different auras Destructive and controlling, his control aura his natural affinity is he can control shadows, the shadows of people, animals, inanimate objects,
You can have two auras and in turn have them merged or used in tandem,
Like a creative elemental, defensive controlling, controlling elemental, destructive elemental, creative destructive, or defensive creative,
Now an example of a One aura user would be
Zoephelia her natural aura is elemental, her affinity is lightning one of the rarer Elements especially for an Angel, despite not being born through a royal family or an extremely powerful family she still stands on equal footing with Kaiser despite him having two auras.
Having multiple aura types does not make you stronger than another person
People with two aura types can have a smaller aura capacity then a person with only one.
Aura pools.
Different people will have vastly different aura pools or even extremely similar in size,
Aura pools are how much a person collectively has. This pool can be increased with training, can be hidden, can be also destroyed, or can even be decreased.
Having two auras does increase your aura pool but no so significantly that it makes you so tremendously powerful, example
Kaiser and Zoephelia are equal in strength but Zoephelia has a bigger aura pool than him despite having only one aura type.
Aura pools can be increased by these methods, training, rituals, or even a transformation.
They can be decreased by curses, detransformations, or even by techniques from control type aura or destructive type aura.
Tiers of power and classifications.
Tier 1: these are just regular people, non fighters and citizens.
Tier 2: these are people who are fighters more akin to foot soldiers with no particular or extraordinary abilities incapable of causing some damage to a singular area
Tier 3: these are fighters who have an understanding of Aura and how to utilize it to destroy small buildings and are a sensible threat to platoons and smaller portions of cities.
Example of these individuals is Kaiser, Zoephelia and Deakon
Tier 4: these are individuals who are viewed as one person armies capable of destroying an entire city and possibly through time destroying larger cities, their auras are more commonly found in denser populations and kingdoms, like heaven,the elven kingdom, and the Demon realm. Princess of the elven kingdom, and the queen of elves.
Tier 5: people who are capable of destroying entire continents they are the second most dangerous people on the planet examples of these people are, Priscilla, Ma'ae, only though two have been met there are many more either in hiding or rulers of their own kingdoms, they are masters of their aura and can use both to an extremely powerful extent capable of killing people with just their aura alone and not the abilities of it.
Tier 6: these Are the defacto Most dangerous people in the world fighting them is a Death sentence,these individuals there are 10, these individuals are thousands of years old and capable of destroying the planet their auras are inconceivable to most people, the pressure they give off is enough to flatten people in an instant if they aren't using limiters or if the person hasn't made themselves weaker to be around others, only one of these individuals have been met/ revealed and that is Kaeya, Kaisers mother, she herself is the sole reason multiple kingdoms and hidden civilizations have been subdued or wiped out.
Curses and the cost of using them or even being cursed.
Curses are extremely dangerous rituals that can cause harm to both the user and the person affected.
Most curses will require blood from the caster to be performed. The stronger the person being cursed, the worst the tax is; for instance, if a tier 3 tried to curse a tier 5, it would require an enormous amount of power and even then it isn't guaranteed to work it would take multiple attempts just to slow down a tier 5
Being cursed depending on who's doing the ritual and what they place on you, can kill you for instance a tier 3 could easily kill tier 1s or a mass group of tier 1s if they choose to but they would still need to give up a large amount of blood to perform it.
Simple curses are just curses made from either the blood, hair or skin or even an object the person owns, these aren't particularly powerful but are more along the lines of after build up of the curses it can become deadly.
For Heavier curses that require incantations these will require the loss of something extremely important to the person doing the ritual, or if they have nothing to offer something is taken from them by the spirits doing the curse , rituals can be done with multiple
People
Each must meet specific requirements to begin and to activate you must sacrifice something, the stronger the person being cursed the more of a tax you will receive.
