When the Titans first crossed the Ancients, they were little more than mindless, beast like beings with defective bodies and minds. But at the years began to drag out, they became far more sentient, their power grew stronger, and their numbers became enough to rival the entirety of the Ancient race.
The Ar'dun, on the counsel of the Great One, investigated the origins of these beings to Hell itself, but could not go to the forsaken realm of old as it was tainted with great amounts of Dark Energy.
Many years later, word spread of an evil that tainted and destroyed an entire world. The Ancients believed it may have been a Titan that had tampered with a dangerous power.
They never thought they would meet the one who had created the beings...nor prove to be far superior to their strength.
Ancients who survived its wrath were left on the brink of death when they recalled the event; the Realm that had been destroyed was little more than a pile of ash...
And it would walk amongst the flames...a great being; twisted, dark, evil...like the Ar'dun but far more powerful.
And it would forever walk as the harbinger of Death, destroying realms across the Universe. They would whisper it's new name with a sense of fear and absolute terror, for whomever felt its presence knew that their life was nothing but forfeit.
They called Him Nu'aga Wrai'danen. The Great Devil.
