Eternity is and abstract being who serves as the embodiment of time. Together with its mate Infinity,they embody all that exists,representing space and time. Eternity came into existence when the universe was born,and has referred to many of the other abstract beings who came into existence with it as both siblings and offspring. This includes the planet-consuming Galactus, sole survivor of the previous universe,whose life was spared when the previous universe's version of Eternity merged with him. Throughtout the Multiverse,each alternate universe is embodied by an eternity of its own. The only being known to have authority over eternity is the Living Tribunal, which is itself a servant of a higher power known as "the One Above All" (not to be confused with the Celestial of the same name)
