Nymphix. They were a rare race of advanced humans discovered by scientists many years ago. Not long after, they were known to all human kind, and naturally, there were those who were jealous. Jealous that Nymphix had abilities to do things that normal humans could not, and a group formed and hunted down every last one until they were nothing more than a myth told as a bedtime story for children. Little did everyone know that those scientists kept seven Nymphix in their lab to experiment on, and after the rest of them died out the scientists let them out into the world. There was all but one rule; they were only to procreate with humans. To make more Nymphix would be too risky, and they were sure to be found by the Hunters so instead they made Nymphan. Half Nymphix, half human. Eventually they were all that were left of the Nymphix...or so they thought.
