Prestige of the Void Elders
Rosen was a man of his word. After he left the Void Senate, he entered Void Peak to seek an audience.
Even for the current Rosen, including all of his improvements, he couldn't casually come to this place without reason. And, even in the case he did have a reason, he still had to be respectful and patient. These individuals, the Void Elders, represented the very pinnacle of the human race. Together, the power they held was enough to be the face of the humans, and it surpassed any individual family.
If this wasn't the case, how could they dare to claim to raise the future generation of leaders?
The Void Elders were formed of a group of men and women with no affiliations to the large families or organizations. They were existences who, over the course of history, could have built up their own families and powers, but instead chose to forsake this path and become the beacon of humanity instead.
