The Void King

The reason no beast dared to approach this place was simple: it was the life forms atop the mountain peaks. Four were in their true bodies, while the others appeared only as incarnations of Ego Wave. 

Those in the form of incarnations were utterly dark and showed no features. Still, this did not diminish the might of their auras.

The mere presence of any one of them was enough to deter even the mightiest of Wave Beasts.

Had Cain been present, he would have recognized two of the individuals present or at least their auras. One was enshrouded in shadows, while the other was a flayed body draped in a thick cloak of Blood Energy. They were none other than the Shadow King and Blood King, the duo that almost obliterated the Blood Sea if not for the appearance of the First Collapsing Lightning Pillar.
