Immediately outside of the walls of the Amnionic Dominion lies an unimaginable liquid cloud of immense blinding light and virtually endless enormous bubbles, containing any possible reality or dimension within them. Like all bubbles, these pop, of course, and form more bubbles, and it goes on and on, never ending.
These volatile dimensional bubbles are the conglomerate dreams of all living things within the Amnionic Universe. They are energy manifested in its purest form, and what generates the egregiously bright light that shines throughout reality outside of the Amnion.
