HUMAN SOULS:
◾ Magic : A select amount of humans possess this ability, and uses it in many purposes (war, healing, etc)

◾There are people who have no magic powers because they don't have an affinity with magic.

Gray Souls:
◾A Grey Soul is a weakened soul. It's not that there is no magic or power inside the soul, but the soul cannot use any power or magic because it means that you've lost your trait or motivation for said trait. They appear as grey and it's an effect of a human losing their trait.
◾This is not considered a trait, but is the lack of one. However, humans that don't possess magic abilities do not have a grey soul. A wizard's soul may turn grey depending on the subject's experiences, they're most likely to be triggered by a traumatic experience. This is not a permanent state
◾ The problem comes when an adult wizard suffers from this. Depending on their trait, having a grey soul may affect not only their magic, but their way of thinking or in extreme cases, even their personalities. A wizard with a Grey soul can NOT use magic.

◾"In terms of quantity, kindness is one of the rarest traits."
◾ "This can be concluded because of the cruel human nature that humans possess. While all humans posses kindness, very few will decide to practice it and live by it with enough will power to make it their trait."
◾ "Kindness wizards, while very rare, are extremely powerful. Their defensive and healing magic is unique, and very well received among their allies."
◾ "Ironically, as powerful as it is, the wizard itself is quite vulnerable when confronting an enemy. Due to their soft heart, a kindness wizard in combat, is more likely to get killed by their enemies."
