For the blind:
Long ago, when dragons once roamed the universe, before the birth of many of the Gods, 2 bloodlines were chosen from two species of mortals.
One was blessed with the power of Light and Fire.
The other was blessed with the power of Water and Ice.
In the Bloodline blessed by the Sun, the blessing was passed from father to son.
In the Bloodline blessed by the Moon, the blessing was passed from mother to daughter.
The blessings granted immense power and strength. Heightening their senses, their muscles, their skin turned to scales.
They were gifted with the power of the Sun and Moon respectively.
Alongside these blessings, two gifts were also given. Two weapons of equal power.
The legendary Guandao of Fire and the legendary Trident of Water.
With these gifts and blessings, the two Bloodlines protected their people from evil.
The one blessed by the Sun continued it's Dynasty through rituals, which activated the hidden power inside them.
The one blessed by the Moon on the other hand hid their rituals, and never passed on their power, but their bloodline stayed alive.
