The mention of The fabric of Existence first began a long time ago during the Age of Certain Certainty and was mainly discussed by philosophers and physicist. Such developments went to waste when the Incident happened and the lack of firewood prompted the burning of such documents on the matter. Of course however, the damage of the Incident caused laws of nature and such to be damaged hence rendering anything discussed on the fabric of Existence to be useless. As such, any mentions of the fabric of Existence would relate to current times laws of nature.
