A Roar From the Depths

The Netherworld Sea appears in the sky. And the Blood Sea boils, and howling seems to come from the Sea itself. 

The apparitions, the ghostly figures that hovers above the Blood Sea fly toward the sky.

And they enter this Sea of Death that floats in the air. 

Nether energy pervaded the Heavens and the Heavens change colours yet it could not stop this Nether energy

It is like the Heavens itself is being eroded.

Entropy, time, death. All of these seems to affect the Heavens. And what affects the Heavens after the world. 

The Blood Sea seems darker, the clouds sems dimmer, the sun and the stars are covered by this dark energy

And with each ghost and figures of the Blood Sea entering the Netherworld Sea, the stronger the Essence of Nether became. 

Separated by millions of miles, but the energy that is gathered by the Netherworld Sea seems to feed into the Essence of Nether that is floating beside Azief.
