Tetrachrome

A Tetrachrome is a person, always a woman, who can see four primary colors and perceive a much larger variety of sensory shades in general.

Before the commoner Baily Lembeck was revealed to be the first Tetrachrome, the Tetrachrome was believed to be a woman who will be born from the Bloodline of the Fae somewhere in Farenna towards the End of Years. Her new perceptions of sight, vision, touch, sound and taste would bring humanity and the Fae into a New Age.

Baily refused to use her powers for the sake of the Dulina Monarchy and this ultimately allowed for Kelbren to take power and wed Elerea, who became his queen. This caused a great loss of faith towards the Dulina Monarchy, who based much of their power and right to opulence on being the sole incubators of the Tetrachromat Bloodline.

It is unknown how the blood of the Fae came into the Lembeck family, but it's believed that it was through one of the Monastery's opulent and corrupt orgies that godblood entered the family.
