Aura (Explanation)

*Aura refers to the luminous field of ethereal energy that surrounds sentient beings in Noblesse. This energy permeates their bodies and is constantly radiating outward. This energy can be manipulated in various ways for a myriad of effects. It is the underlying concept behind as well as the foremost of many of the supernatural powers.

Nature of Aura

-Aura is the supernatural phenomenon in which the potent, internal energy that appears comes from the soul and is manifested as a powerful force on the outside of their bodies.

Aura manipulation and perception are abilities that can be unlocked through various means, whether strenuous training, technological enhancements, or in the case of some beings, (e.g. nobles) naturally. The true nature of aura is the fact that it's fundamentally linked to the soul.

Characteristics:

*Appearance: Auras usually take the appearance of colorful flame-like energy radiating off a person. However, some auras look akin to electricity or even steam. Weak auras are typically invisible, or take on a subtle, pale gray glow. More potent auras cover a wide spectrum of colors - red, blue, purple, green, white, orange, etc. The color of one's aura seems to relate to its intensity.

*Presence: Because of the aura's nature as the manifestation of one's spiritual force, it has a distinct feeling to it. If one can familiarize themselves with the "feel" of certain auras, they can detect whenever certain individuals are present. A portion of one's aura is released whenever one uses their powers. 

*Type:  It has been explicitly stated that each of the different species has distinct auras, characterized by the average measure of spiritual power those beings have. For example, human auras are generally weak because the vast majority of humans lack the power to release and manipulate their spiritual energy. Races that are generally more aware of supernatural phenomena and have an affinity for manipulating their spiritual energy (e.g. nobles), have stronger auras.

*Radiation: Aura energy is unconsciously radiated by the majority of beings. However, one can train themself to consciously radiate more energy for a variety of effects. Also, even though aura naturally radiates off a person, the release of energy can be cut off.

*Psychological Effect: Aura is a unique force because it affects living things not just in a physical way, but also mentally and emotionally. It is a medium through which your thoughts and emotions can be expressed and detected. Auras can express hatred and bloodlust as well as instill fear and awe. These emotions, when detected by the enemy, can overwhelm their mind, sending them into a stunned state for a short amount of time. Aura amplifies emotions to the point where they can cause physical effects such as momentary paralysis, sweating, pain, violent shaking, etc. Because of this, combatants with strong auras can dominate their enemy just by releasing their aura.

Usage:

*Empathy: Aura is often used as a medium through which powerful emotions can be conveyed. Aura, at its core, seems to be a force that is able to create empathy between two or more people. Powerful emotions can have psychosomatic effects on the people sensing them. Auras that exude violent, wrathful, vengeful, or sorrowful emotions, are called "dark auras". The potency of one's aura is greatly affected by their emotional state and personal psyche. Powerful emotions can enhance the power of an aura, not just in the destructive sense, but in giving it the power to affect people on a subconscious level.

*Catalyst: Aura can also be used as a catalyst for unlocking or releasing certain things. Due to its nature as a personal power, it is often used as a trigger to reveal messages left for specific people[1]. It can also be used to identify whether or not an individual is able to view or use certain objects (e.g. soul weapons).

*Physical Enhancement: By willing yourself to release larger amounts of aura, and then channeling that energy to a specific body part, one can enhance greatly their physical ability as well as other abilities they might have. However, this burst of power is typically brief and exhausts the user. Also, powerful wielders of aura can cover their entire body with their aura. Users can also create explosions with enough force to wipe out a large portion of, if not the entirety of, a city (depends on the strength of the user).

*Detection: Similarly, aura is used to detect certain people. As each aura has a distinct 'feel', it is easy to determine when a certain individual is present at a specific location or using their power. 

*Energy Projection: Aura can also be applied in battle. Beings with naturally more powerful auras (e.g. clan leaders) can highly concentrate it and manipulate it within a battle. For example, clan leaders can manifest the symbol of their clan with their soul weapon's aura. This is their most powerful attack as it releases the entirety of their powers in it and travels at a blistering speed to strike their opponent. In addition, because aura can interact with normal matter, its power can be tapped into via highly advanced technology, allowing for a myriad of beings to accomplish this. Aura is used to create extremely durable force fields, explosions, and destructive waves of energy. Most commonly, aura is concentrated and fired from the palm as a powerful energy beam, capable of leveling multiple city blocks. Aura can also be used to overwhelm the enemy's senses, effectively paralyzing them. Aura users with high control can also create solid aura constructs and manipulate them mentally. Things like spikes that can be used to strike an enemy.

*Crafting: Aura can be manipulated to forge objects with supernatural properties, such as suppressing one's own life force. It seems that the process involves envisioning the object you want to create and then releasing waves of aura energies of varying intensities to form a dense point of focused aura. This 'singularity' then begins to take on the shape and characteristics of the object in mind. The object retains small amounts of the wielder's aura. This process needs a lot of Aura so only those with high amounts of aura can do this.

*Pseudo-Flight: A passive ability used by the majority of characters, particularly nobles. This ability allows them to levitate for extended periods of time and to fly short distances at high speeds.

*Transmutation: Aura users with high control have the ability to transmute their aura into a natural form of energy: for example electricity. (This is an added feature of mine, although it is in canon too but only Regis has shown it so I changed it into aura users with high control).
