A young Fyodor Dostoevsky lives with his mother and older sister, slowly reaching poverty. He is a sick and feeble kid who starts attending a new school, and finds himself being made fun of for his illness. Through his mistreatment he discovers his ability, and accidentally uses it. This ends up resulting in him creating the idea to rid the world of abilities, to rid it of "sin."
Or...
The fan fiction where I read two interesting theories regarding Fyodor Dostoevsky from BSD, combined them, and wrote a story by using the two theories as guidelines to revolve around Fyodor's past to make them more or less "believable." This is full interpretation and fully creative writing on my part!
