Necromancer: The Angel Of Darkness
Born of blood and yet so disgusted by the sight of it, that was Sephtis, the greatest necromancer the heavens would ever know and also it's greatest nightmare to come.
Sephtis, a being who was most surely not human but neither was he a demon nor a beast, hating the sight of blood yet there exists no greater master in the art of slaughter than he.
His ever growing army razing down cities, countries, continents, entire worlds and eventually perhaps everything else. He was the definition of a nightmare, his name alone scaring even shadows away and his presence leaving nothing but destruction everywhere it touches.
And to the world's greatest surprise something incredible had happened, the unstoppable force had vanished from the surface of the world one day with no explanation nor answer as to his whereabouts. The world finally knew peace, the gods were praised for an entire month straight for answering their prayers, losing themselves in wine, music, food and carnal desire, this was heaven.
But as always peace is never a long-lived thing, Darkness is never really truly gone, only just temporarily withheld and the greatest nightmare in history would be returning once more, this time so much greater than ever before and making sure that he completes his mission without fail.
