He was the ruler of a great empire and was but one step away from his coronation as king of his divided homeland. With The Darkness he intended to unite the warring principalities and vast dominions under his crown; to establish a new monarchy, a new hierarchy, a new Hell on Earth with none to stand in his way.
He was tricked by a nobleman, Issiah Rainmaker; who offered him a mortal woman disguised as The Angelus to him as a servant. Christian accepted the offer and killed his mother when she tried to kill the woman. The woman had sex with Christian with the intent of becoming pregnant with his child, thus killing him.
The plot was successful and Christian died as the sun rose over The House of Estacado. The woman lit the funeral pyre for the fallen prince.
