Aura

Aura is a projection of ones soul, a bright outline around a person. It was said that Aura could tell what a person's personality was just by the color. Red for outgoing, outspoken people and blue for strong leaders. For a while it was just a myth, until people began to see it. Certain people could not only see the Aura of others but could also manipulate it. Use it to control other's emotions and thoughts, creating a new race of humans. A very dangerous one. Shunned from humanity they were kicked out but now they want revenge.
