Sun Quan

 was the Master of the Aransu School and Sanzu's father. He was a very doting father but struggled to control his willful and stubborn daughter. He also bore the burden of keeping the Aransu Sword and the clan secrets safe.

Second Arc
Following his death, his spirit lived on in a mysterious scroll within the Ebondrake Lair. The Hongmoon hero awakens his spirit who offers to show the hero how the darkness works in hopes that they may help him save his daughter. He transfers the hero's consciousness into one of his daughter's previous bodyguards in the past.

He explains to the hero that the day Jinsoyun fell was also the beginning of his daughter's downfall. That ever since his death, Sanzu devoted her entire life to rigorous training and ancient teachings, even joining the Eight Masters in her bid for power. However, he laments the fact that it also made Sanzu very vulnerable to the same darkness that had killed him.

He explains that Sanzu took on the name of the Aransu School founder, Zulia, because she found it easier to be someone else that accept the reality in which both her parents were dead and she had failed to find vengeance. He fears that the darkness is turning his daughter into a demonic version of Zulia and beseeches the hero to save her. He regrets the way he had treated Jinsoyun, understanding that his actions pushed Jinsoyun to the darkness. Rather than have the hero repeat his mistakes, he wishes the hero will chose to save Sanzu just as they once saved Jinsoyun.
