In the primordial times, the Divine Beast Origin was ruled by three Beast Sovereigns. Their strength were comparable to Heavenly Sovereigns. They were Primordial Undying Bird, Primordial Myriad Spiritual Bird and Primordial Desolate Beast.
When the Divine Beast Origin was destroyed, they launched a counterattack that dragged five Monarchs of the Fiend Clans along with them, and sealing those Monarchs.
