Duan Hen

After his Father died he became the City Lord of Twilight city but because his age he was only a figurehead.

He made a deal with Shen Yanxiao that if she would help him take the throne of the Seven Kingdoms he would give her his territory in the Barren Lands.

When Lan Fengli assassinated the Elders of the Seven Kingdoms he used that opportunity to take control of the Seven Kingdoms. He eventually had to kidnap the children of the seven kings to make them fully submit to him.
