Magic is both a type of special power and a special class of skills in Etelldia.
In order to use magic, an adventurer must have magical power within them and then be able to perceive its flow, since magical power is the foundation of magic. After being able to perceive the flow of magical power, it is essential that the person be able to control the flux of the magical power in order to properly delegate the right amount of it that is needed in order to invoke a spell and to control the strength of that spell.
When talking about magic, it can broadly be defined to two different ways of exploiting magical power. One is manipulation, the other is for creation. For example, wind and earth magic come in the form of manipulation of the surrounding elements, but water and fire magic come in the form of creation where it is necessary to create the element then manipulate it.
