Intro. He was born in heaven - in the world of light, but he himself became a product of sin. Mother, Angel, had two sons: Abel - beloved, legal, and Cain - born from forbidden love. From birth, he became a stranger, a symbol of betrayal. When both fell ill with deadly angelic ailment, the mother chose to save Abel. But Cain survived - a broken, with the power of his brother, corroding him from the inside. Strength brought not salvation, but madness. Mother expelled him from heaven. On Earth, a priest sheltered him, taught prayers and playing on the organ. But the voices in the head did not subside. Then Baal appeared - a original demon who promised deliverance for the price: the death of the mother. Cain killed her without hesitation. But the demon lied. The apocalypse has come.

Only the founder and cryptographer Lane, found three years later, survived. On the wreckage of disasters, a new base was built - Adam.
