Pralaya from JL has also done the same thing erasing the whole DC from the void . That story treated the Multiverse containing infinite dimensions as well as infinite universes . She literally blinked the DC creation out of existence with a wave of her hand .
She is said to be an aspect of darkness that predates the light referring to Great Darkness himself . And also Night who created the endless and responsible for the outcome of every creation is said to be the embodiment of Darkness from which all of creation is formed .

The Source exists beyond all lvls of the multiverse inside the white void empowering everything in the creation
