An aura is a thin layer of mana around a being with a soul, visible with the use of Seeking Magic. Each individual has a unique color and hue of aura, although similar colors are often passed on in bloodlines.

Historically, elves believed that the aura color was indicative of a person's innate Talents, and hence trained their children in the associated Talents. It took a very long time for this to be disproven, resulting in a persistent general belief among Elkandu in the correlation between aura color and inborn magic.
