Throughout the universe, it was a known fact that Mythical Bloodlines were the topmost desire for any half-blood descendants. 

In fact, for a human to have any drop of bloodline legacy would have actually been considered special already.

The people of Ouroboros understood this fact through the ten millennia of war between those who possessed the blood of the Serpent and those who didn't. At the end a thousand years ago, the 1% minority of the bloodline race was the one who won the war and became the ruler of the planet.

Since then, every citizen who had even a seemingly insignificant rank 1 bloodline would be considered an upper-class citizen, a title that allowed one to receive special training and education.
