The image is a diagram with a dark background. A large black circle dominates the center, surrounded by a thin white circle. Inside the black circle, the text 'REALM OF CHAOS AND OLD NIGHT' is written in large, bold, serif letters. A vertical line extends from above the circle to below it, bisecting the diagram. Above the circle, the text 'HEAVEN CULMINATING IN THE MOUNT AND THRONE OF GOD' is written in smaller serif letters. The vertical line above the circle is labeled 'Heaven-Gate' in small serif letters. Below the circle, the text 'HELL, TERMINATING IN THE BOTTOMLESS PIT' is written in smaller serif letters. The vertical line below the circle is labeled 'Hell-Gate' in small serif letters. The overall aesthetic is reminiscent of a medieval or occult diagram.
