The Dan-Tai Empire birthed twenty-three daughters and he was nearing the end of his life span. After living for over three centuries and watching half his daughters wipe the other half in the struggle for succession to the throne, he decided to put an end to this in a peaceful way.
Whoever could bring the most worthy suitor, will take the throne and rule alongside her husband.
This was the only way he could shift their murderous intent away from each other and focus that energy on something more productive.
Nixara was the third of the remaining ten princesses, scattered across the galaxy in search of a worthy spouse and Lucius was the answer to her question.
In his current form, his lifespan was on par with hers, if not superior. He has the potential to become the new pioneer of the empire, something she knew had greatly bothered her Father for centuries now.
If she could support Lucius and win the battle for Earth, wouldn't her fame even grow?
