The coils of the World Serpent
Many Millennia ago the gods went to war. They took many of their followers with them to the battle of Mount Deismar. During this battle eleven of the greater gods fell in battle. When these gods died those in close proximity to them at the moment of their death absorbed much of their essence. So was born the the Blooded Scions.
Many of those with the new found bloodlines went on to become rulers of nations. It seemed that those who carried the blood of Gods had a greater affinity for magic and ties to the land. Most Scions developed unique powers which allowed them to surpass regular mortals.
Then came the Wars of the Scions. It was discovered that if a Scion defeated another scion in battle they could absorb some of the Strength of that Scions bloodline. This discovery led to wars between those Scions who craved greater power. In the ensuing wars three of the bloodlines were completely destroyed.
