Magic
In this world magic is known as Nexu. The fae possess unique organs that grant them the ability to adapt to the Nexu style they use. However, this ability only becomes accessible after they have gone through puberty.
​
All abilities can be traced back to one of the seven natural elements of the world. They originate from either water, earth, fire, air, nature, electricity, or even that of shadow. Fae can pass their abilities on to their offspring if the child is lucky enough to be born with it. This is the second most common way for an individual to receive the potential for nexu.
Newly turned fae do not possess nexu, and even those born fae may not have gained his or her parent's abilities. However, an individual could receive the gift of nexum through blood binding. Blood binding is when a humanoid makes a blood oath with another. This is in order for one individual to receive the same type of magic as another. The individual seeking abilities is referred to as a tumulus. Those who give the gift of nexu through blood binding are known as a pelagus. This deal often comes with a contract of service from the pelagus.
All forms of nexu can have the potential to be enhanced in order to become stronger. It also can even evolve. Through training, a person can alter their magic in order for it to become something different. The family's nexu type can be changed as it is passed down through the generations. This allows the nexu to become something entirely different. As the power is passed down from generation to generation, the ability could transform from using earth magic to manipulating sand instead. Controlling water could lead to forming ice. Fire bending could turn into the ability to use lava at one's will.
Although an individual can be born with the potential to use nexu, a humanoid will not develop the ability to use it until he or she goes through puberty. Once he or she uses nexu, the young fae must learn to control it. The user must exercise caution when using nexu, as it might destroy them both physically and mentally. It could cause the being to lose all control of his or her sanity, or even cost the user their own life.
