The Magician.
The center piece of the "THE" universe, although he(?) may not be constrained to it. There are several being that fufill the role he has left in other, close universes. Although these should not be confused with the Magician it self. The following are confirmed: The Pirate, The Mockup Rodent, and allegedly The Glitch.
How The Magician achived godhood and thus ascension of the self is unknown by the gerenal public, although leading theories is that he made a deal with a powerful cat in order to achive his new position, or, through an act of huberous, errased himself from human existance, leaving all that's left in the spaces between.
The Magician is closely associated by his reportedly remaining companions, although it's unknown if they were such or these claims are a late attempt to cash in on this alleged God. The names of such as The Maden, also known under the allis, the Flower, and Time itself, or The Other One. Maybe.
IT'S ALL A TRICK OF THE LIGHT. SLIGHT OF HAND. TO TRUST A CON-MAN IS A FOOLS ENDEVOR. OF COURSE THERE IS NO SUCH THING AS GODHOOD, JUST THE SPACE REMAINING AROUND IT. THE ABSENT OF SOMETHING MAKING IT SO THAT IT IS THERE IN IT'S ABSENCE. HOW CRUEL. HOW CRUEL.
