There are many myths
There are many myths among the world of men regarding the creation of existence. For the 12,000 years of your history you have passed these as fables, and lore and myth, from man to child and beyond. They have been your comfort and guidance. From them you have taken morals, laws and strength. They have all been wrong. I am Ios, a creature of no particular note. I am a Watcher tasked with chronicling your world and all that is, was and will be. Much of what I will say will be beyond your comprehension. Much if what I say will appall your sensibilities and shatter what has been the foundation of your world. What I speak is the truth of your beginning.
There was no beginning, not as you suppose or conceive, for all that exist has always existed. You do not remember your past yet you have lived for all eternity. As have I. We are the same though our form should lend that we are not. But far enough back, before you were human, or primate of cosmic dust we were only one. The great entity, it has no name, for names where never, needed. It has no voice, for there existed none to hear it song.
The Oirey have called it Oi-Ru, for your language we have called in the Singularity. There came the Event, the one great moment in all creation when the Singular entity.
