Eternal Plane

The Eternal Plane is the first and oldest of all planes of existence. At first simply an ever expanding void of darkness its grand dominion was suddenly changed with light manifested at the Umbral Heart. Darkness turned from its expansion and attacked the invisible burning at its core causing the creation of the Prism, forever separating darkness from light.

This plane of darkness was cast out into the expanse it had created and was restricted to an cosmic axis opposite of the Celestial Domain, it was only then that the Eternal Plane went from a neutral void of the cosmos to the home its greatest evils.

Birth of the Elders
Fracturing itself following the events of First Lights Grave, darkness would fall into a deep slumber as its eternal essence manifested into the negative energy known as Null, which spread through the Prismatic Planes infesting the space in between stars and corrupting the strongest individual entity within each domain. Once the darkness has spread throughout the vast expanse again it focused its attention on the celestial and material planes, seeking to again have control of all that it had lost.

The corrupted powers of each domain would eventually chose their vessel mutating into seven powerful dark beings, these beings would become known as the Elders. The Elders quickly began conquering and consuming the essence of their respective domains, creating dark beings known as Eternals to do their bidding throughout the cosmos. These actions would force the Celestial Plane to react and the Prismatic Wars would begin.

The Eight Elders:
Near the end of the Prismatic Wars an Elder persuaded the Songbird Duet to betray her sisters to the Eternals leading to great losses suffered by the Celestials and eventually the end of the war following the Pact at Dawn. Duet was cast out from the Celestial Plane and became corrupted by the null, becoming Duet, Fallen Vengeance.
