Francesca is accustomed to privations and hardships, this has made her body thin and skinny, but also her will strong and unbendable!
I've never told Francesca's story, but, in short, she lives her youth in a some remote temple, as a servant of some female order, locked in few rooms, mostly totally alone, trained to hate and fear of men, rejection to every human contact (forbidden to exit to the sacred halls, to talk, show her face, meet people, be seen or touched by anyone) and accustomed to bear constat privations and regulars "purifications" through suffering.
When they stole her, they thought could be easy to bend a young girl who lives in fear of men and knows nothing about the world, but they undervalue her strenght. so her taming is harder than expected...
