Aura is a mysterious power that permeates all of nature, it allows individuals to harness their own spiritual energy for various superhuman feats. In its purest form, it's not something that can be seen by those who don't have access to it.
It's considered a dangerous power by the State Court and therefore prohibits the public from having access to it. Only those with the occupation of an Assassin are allowed to use it.
OVERVIEW
For the most part Aura manifests in the same way in every user, but its proficiency and intent are dependent on the user. It is an intangible force of energy inside every living being, with its major focus being the soul of the body. Its common application are the subtle physical enhancements, however these can go beyond superhuman levels if the user develops their body. And through certain training can users gain a Special Trait.
SOUL GATE
The Soul Gate is a metaphysical barrier that separates the soul from fully overlapping with the flesh. This gate naturally inhibits a person's capability to manipulate Aura. For someone to awaken and gain access to their Aura, then their Soul Gate must be unlocked by a Diviner.
In Diviners, a Soul Gate is nonexistent, so it mostly effects awakened humans.
Overexertion can cause it to weaken and destabilize. Without proper maintenance, the user risks serious physical or spiritual consequences. Its reason why a skilled Diviner is required to re-align the gate to restore balance.
SPECIAL TRAITS (Vol.2)
SKILLS
Having access to Aura is only the first step, but controlling the degree of its emission usually takes a certain amount of training
Basic
[Shroud]
The user cloaks their whole body or specific parts with Aura to amplify their physical attributes such as strength, speed, or durability.
[Sensory]
Allows users to detect the Aura of others around themselves like invisible signatures radiating from living beings. As Aura reflects a person's sense of self, users can be able to distinguish others not only by strength but by the subtle differences in color and energy.
[Clear]
It allows users to suppress their Aura to make themselves undetectable to others. Through immense concentration, users can silent the sounds of their movements such as walking. In extremely rare cases, an assassin could master this skill to an extent that the person becomes invisible not only to detection but to perception as well. It went beyond just suppressing Aura, it was as though they had completely erased themselves from other's awareness entirely.
[Conduit]
This one is more automatic than manual. It allows users to channel their Aura into Enchanted and use their latent Aspect Abilities.
Advanced (Vol.2)
LIMITATIONS
As manipulating one's Aura isn't a natural occurrence. Those who aren't Marked by an Arcana Card face significant risks and constraints.
Overexertion
Prolonged use can destabilize it, causing physical strains, mental fatigue and then finally, uncontrollable surges of power which might lead to an explosion, in rare cases.
Maintenance
Without proper maintenance of the Soul Gate, users may find themselves unable to control their Aura which might cause power surges and then an explosion.
This information isn't set in stone. As the story develops and more concepts are added. It might change, but I will keep updating it with each end of a volume
