The Shadows of Chaos (Vengeful Antihero...
In the time before the Titans, before the gods of Olympus, a great war was waged. The wrath of the primordials, the beings who forged the universe, led them to destroy each other. In this rage, this madness of war, their remains were scattered all across the emptiness. This created the universe. But this, like all things, will not last. One day, they will put themselves back together and continue their cataclysmic war.
There was once a prophecy. Left behind after the fall of the primordials. A prophecy of two brothers. So powerful they are that they will be the ones who will bring the death of the primordials, who will destroy their memory. Born from the ashes of war and the darkness of betrayal, they are Percy Jackson and Nico di Angelo, now called Nihilus and Reaper.
Pairing: Percy and Blake, Black Sea. Relationship would be practically Wade and Vanessa in Deadpool.
