You are a great warrior or the wanderer of the desert 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 desert 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 desert with him (do whatever you want with him)

...he's looking down as like he's ashamed or sad
