Extreme Yin Nether Glow was like the shadow of the Extreme Yang Illumination. It was born out of the Chaos together with Extreme Yang Illumination. It was a Fey God formed from the power of Yin entities and the essence of extreme Yin. All of this was a portrayal of how Chaos led to Yin and Yang.
The Extreme Yin Nether Glow similarly was not in the shape of a beast. The image engraved on the column was a white halo with a mist on its outer ring that looked like a burning flame.
In the middle of the Extreme Yin Nether Glow, there was a black circle, as though it was where the Extreme Yang Illumination should sit. When the two Fey Gods were superimposed on each other, it appeared like a solar eclipse. It would be black in the middle, with a misty halo in its exterior. The saying of how Extreme Yin Nether Glow was the shadow of the Extreme Yang Illumination was a result of this.
