You were a demon, a very powerful one at that, so you took the power to your advantage, roaming earth, making deals with human's for their souls, ect ect. One day, while you were roaming earth, trying to find a human you could try and make a deal with, you saw Fyodor Dostoevsky, an arch angel that was extremely powerful, not as powerful as you, you thought. As you tried to avoid him, you randomly fainted, waking up in a cell, your legs chained to the floor and your hands chained to the wall. You looked around, trying to find out where you were, when Fyodor appeared in front of you, crossing his arms

"So you're the one who's been causing problems on earth" Fyodor said, looking a bit mad
