Maryoku

Maryoku is the mental and spiritual power of any living entity. A being that is capable of utilizing their Maryoku is able to cast spells based on the nature of their inner power; somebody who is hot-headed and impatient, for example, may have the ability to cast spells based around the element of Fire in a variety of forms and variations such as lava, steam, and heat. Maryoku within an individual is capable of changing, and may adapt based on knowledge or outside factor. A being is able to completely change their Maryoku over time due to events they have experienced, though such an occurrence is rare. Certain individuals may experience a complete change in the quality of their Maryoku due to their absorbing a piece of another being's soul, such is how Mages are capable of teaching Magic that they have mastered to other non-magical human beings.
