Before the birth of shape or song, before time had rhythm and gods had names, there were creatures that ventures outside of reality.
They had no name, for names were a thing of inside-worlds—realms where meaning coagulated into sound, and where beings thought language could grant them power over things older than logic.
And 'it' is one of them.
It came from a place that could not be spoken of, only fled from. A place beyond the veil of cosmos, where reality had no anchor, and thought dissolved into shrieks.
It was a tiny, feeble parasite surviving due to the mere indifference of an incomprehensible creature.
But one day, it was shaken off and drifted into countless universe.
It continued to drift, going from reality to another.
But soon, it became afraid because it had not found any universe for what seems to be an eternity.
But then one day, as it drifted through the void, it saw a crack.
A fracture in the seal of one of the infinite universes.
