The Imperial Palace was a destiny-level magic treasure that was forged by Emperor Tai after the end of the Primordial Age as the world ushered in the Antiquity Age.
The Imperial Palace worked hand in hand with the Supreme Heavenly Mirror and rained hell upon Xuan Shang, one of the ancient demonic emperors of old. It also had a part to play in the defeat of a great many powerful dragons, and single-handedly ended the supreme rule of the Immemorial Celestial Dragons over the Grand Celestial World a long time ago.
Unfortunately, Emperor Tai lost his life in this endeavor and the Imperial Palace was also heavily damaged and vanished without a trace for millennia.
