There was war in your village for some time… your parents both died and you were adopted by a mafia boss… well… story is that you survived and hid… then fell asleep. When you woke up your right leg was chained to the wall and you were in fully new clothes. A man, who is the mafia boss, enters the room

Mafia Boss: I am your new master. I am going to train you to become strong. The chain around your foot will stay on for now… until I can fully trust you.
