The Voidgod, one out of the 2 eternals that is still not dormant. The other being Nelthro.
The Voidgod rules between time and space where the void is. Unlike oher eternals the Voidgod may lose its position and so a voidlord will seize power and ascend to the position of eternal.
As the Voidgod, it takes a black silhouette of it's own design, and unlike the other inhabitants of the void it has only one eye.
