Overvoid

Overvoid

Notes: 

Monitor-Mind The Overvoid, also known as The Void, The Overmonitor and The Primal Monitor, is the ultimate source of all creation of the DC Comics Franchise.

An infinite stretch of pure white, The Overvoid exists beyond all understanding and levels of reality, and is the canvas of all possible creation, with the whole of DC Comics, from 0-Dimensional Bacteria to beings such as The Presence being nothing but non-existent fiction to it.

According to Grant Morrison, The Overvoid is the comic book pages that fiction gets drawn on.
