The Creator God is an unseen character from Evenicle, who created Mother Eve and the world in which she was to live. The creator god's influence has been minimal since those early days, a fact that has raised the ire of QD, who believes he should have done more to protect Eve from the events that followed. She has plotted revenge ever since. Much of QD's assistance to Aster during the events of Evenicle can be partially credited to her planning and scheming against the Creator God.
Little is known about the Creator God himself. He could be seen as an analogue to the Rance World's Ludo-Rathowm, up to and including the fact that the average mortal knows so little about him.
