Light magic is a transmutation type of magic that is commonly used by elibu. This spell can be used to create and destroy light in the area of its affect or where the area the mage targeted. Mana is transformed from energy to light and vice versa. Elibu often use this for lighting up their surrounding or changing the color of objects. This magic could also make objects invisible by manipulating light so that no light shines upon the target.
The light magic allowed mages to change the wavelengths of the light frequency that the object was reflecting and absorbing that resulted in changing the color of the object. Because of elibu could manipulate the wavelengths of light, they could also be able to create illusions. In episode 14, Elaru Wayvin taught light magic to Kiel Rroda on how to conceal his mark of Aetherneal Bond by making the mark the same color as his skin color.
