Omnipotence City is where gods from old, long gone worlds find themselves and offer wisdom to the next deities, where the collective divine knowledge is consolidated. And lastly, when situations beyond all belief come to bear, this is where the gods meet to plan their move.
Shortly after the divine seeds on life-bearing planets bore fruit the various pantheons recognized each other across the cosmos. They met, and together decided to create a permanent fortress city that would serve as a neutral space for all further generations of divine beings.
Ever since it has served as a nexus of the gods as a divine library, refuge, bunker, and "retirement home" for gods whose worlds came to an end.
