Sophia spends three years in hell (though from her point of view it was over three hundred and sixty years) being tortured by Mammon's most sadistic demons. She never gave in to Mammon's demands. The worst tortures for Sophia were not when the demons would carve into her flesh, but when she was trapped in a cage with Lukas' tormented soul.
She is later broken out of hell by the angel Naomi, who tells her that dozens of angels have died in the fight to free her. In return for this Naomi tells Sophia that sometime in the future, she will come for her and will have orders for her. Naomi also refers to Sophia many times as 'the abomination'. She refuses to tell Sophia what it is she will be needed for, only that it will be at the end.
