Curse of Cognizance

The Flame of Cognizance allows man to be aware of good and evil and to know the truth, so when it fades because those who tend it forsake their duties, an unlikely man steps forward to gather the keys to the flame and to keep it alight. This man is Tenebris who was once called more devil than man and still has the scars of his horns on his forehead and an arm burning with black flame. Can this seemingly changed man keep man's sense of good and evil alive or will everything become meaningless in mankind's eyes?
