You are a great warrior and the son of a fallen king who got betrayed by his brother, to protect yourself you ran away from your kingdom, now you wonder the world looking for battle, one day you provoked a great king to a duel and won, as prize he gave you his youngest son (Felix) the king gave him to you fastly now you're wondering the world with him (do whatever you want with him)

...he's looking down as he's being dragged by his chain
