Prince Ur-Demon
Prince Ur-Demon is a celestial who betrays the Saint-Emperor Dynasty for the Vile-Emperor Dynasty. He fights Bai Xiaochun, is captured and later exchanged, and helps lead his dynasty after the Vile-Emperor's death. (Chapters 1081–1213 and 1258–1267)
Biography
Defection, capture, and leadership
Prince Ur-Demon is introduced when Preceptor Seadeep rejects his attempt to call Chen Su “Master,” declaring that his betrayal ended that right. Serving the Vile-Emperor, Ur-Demon joins other celestials in pursuing Bai during struggles over sovereign remains. Bai eventually captures him and Reverend Devourer, keeps them as bargaining chips, and releases both only when the Vile-Emperor demands their return as part of a political exchange. (Chapters 1081–1213)
Despite that humiliation, Ur-Demon later sends Bai an expensive congratulatory gift. After the Vile-Emperor dies, he speaks for the remaining celestials and joins them in mobilizing the dynasty's demigods without waiting for Bai's orders. He remains alive and politically active at his last appearance. (Chapters 1220 and 1258–1267)

He is a Celestial Realm cultivator able to participate in coordinated pursuits of other celestials. The selected evidence does not name his core technique or explain his unusual title. (Chapters 1081–1160)
