On their 16th birthday each person gets a tattoo with a color that determines their aura that will come with special powers. 2 years later on their 18th birthday their powers are fully developed. The tatto is not fully completed till the individual has physical contact with their soulmate. Only then does it finish by engraving their other half's initial in their auras color.
