The Infernal Spirit World.
A century ago.
Within the ocean of a huge valley beyond the reach of sunlight from the world's surface, darkness became a constant rhythm in this part of the world.
In the midst of darkness, a patch of blood-red light flickered like a beating heart. A school of tiny octopus, glowing in a hue of phosphorous green, was hunting for their prey around the dark red glow. Yet, none of them dared to approach it.
The blood-red dim came from an undersea rock twenty over meters in size. It was completely round and smooth.
Images of fire-elemental creatures that defied the natural laws of the Infernal Spirit World occasionally appeared on this blood-red rock. The elemental giants were huge and imposing. They looked fearsome.
Poof…
Suddenly, in the midst of darkness, a pair of blue eyes blinked open.
