"Before there was light, before there was God and the archangels there wasn't nothing, there was the Darkness. A horribly destructive amoral force that was beaten back by God and his archangels in a terrible war. God locked the Darkness away where it could do no harm, and he created a Mark that would serve as both lock and key, which he entrusted to his most valued lieutenant....Lucifer. But the Mark began to assert its own will, revealed itself as a curse and began to corrupt. Lucifer became jealous of man, God banished Lucifer to Hell, Lucifer passed the Mark to Cain, who passed the Mark to you—the proverbial finger in the dike."
— Death (Julian Richings), Supernatural, Season 10: Brother's Keeper
He who will find the secret of my life at his feet, him will I serve until beyond time.
He who shall evoke me in the seventeenth century, beware! For I cannot by fire be destroyed.
He who shall evoke me in the eighteenth century, beware! For I cannot by fire or by water be destroyed.
He who evokes me in the nineteenth century, beware! For I cannot by fire or by water or by force be destroyed.
He who in the twentieth century shall dare evoke me, beware! For neither by fire nor water, nor force, nor anything by man created, can I be destroyed.
He who in the twenty-first century evokes me, must be of God's hand himself, because on this Earth, the person of man existeth no more.
