Sometimes, monsters find their way into the trust of a woman, and exploit her weaknesses. Sometimes, these monsters have children, and then those children have children. The seeds of darkness remain dormant, waiting for the right soil in which to grow.
Prior to his fall, the Dark King bedded a maid. It was a calculated move: he wanted his bloodline to continue. Galbatorix wanted an heir, regardless of what would happen to his kingdom. His heir, in his mind, would one day rise to greatness, and regain whatever he may lose.
When the Warden began marching to Urû'baen, and when the elves took Gil'ead, Galbatorix send the maid that he had created his heir with to run and hide. She did so, stealing away in the dark of the night. She hid her son, and her son's daughter, reminding each growing child of who their ancestor was: a mighty king, with all the world at his feet. Despite their ancestor's wealth, the descendants lived poorly. When Morena, mother to Galbatorix's first and only child, fled, she took next to nothing with her. She took only a pair of dresses, to be passed down.
Time passed, and things changed. Within fifty years, the elves and dwarves united under the joint rule of Queen Arya and King Orik. The humans began to worry, feeling insecure in their own weakness. Soon, though, the elves and dwarves extended their friendships to Nasuada and her subjects, who accepted. The three races were finally united under one flag, with peace reigning. The cities destroyed during the war were rebuilt, and Urû'baen regained it's true name: Ilirea. Trade flourished, and the Black Hand was eventually eradicated.
Another 50 years slowly passed, witnessing the birth of yet more of Galbatorix's descendants, and ushering in a whole new shock:
The return of Eragon Shadeslayer.
Or rather, his dragon, Saphira. As she later explained, Eragon had remained behind to take care of the place the eggs, and to keep watch over the place that the two had found. Across the Hadarac lies the place, Saphira had reported when she arrived. I will take the strongest magicians with me, so we may build the place where future dragons and their Riders may train..
Arya provided the magicians, and Saphira once again returned to the far side of the desert.
Years passed... Galbatorix's descendant grew... Saphira once again returned, this time with other dragons in tow.
Beware, injustice and crime, for the Riders will rise again, was their message. The dragons carried eggs, and with their advice, the circulation of eggs among the cities began again.
Here begins our story.
