The Aktinovolía

The Aktinovolía is the point in time where The Grand Source first began to radiate in Light, and the point where the first world was born. We know this event happened because the world prior to The Keyblade War was always expanding, and we're pretty sure the Fosiverse isn't infinite, and separately sure that there wasn't an infinite amount of time prior to said Keyblade War.

The Aktinovolía is therefore the first event we know about-Nobody knows what came before The Source, after all.

--Trivia--


 * Given that spacetime is emergent from information, some have theorized that Light and information have a relationship with each other, and thus, without Light, there could be no spacetime, making it meaningless to ask what came "before" the Aktinovolía.
 * Others have theorized that perhaps something else, perhaps even older than the Fosiverse itself caused the Aktinovolía. However, that something would necessarily exist outside of the Fosiverse, and hence, would be unobservable to us. This is why we don't take the existence of such a being into account.
