    Qui suis-je ?
    
    Me voici Sultan !
    Nuitisme vocal
    Silice mouvant
    Io, vent musical !
    
    Le voici musant
    Mot inclus à vie
    Ce motival insu
    Là vous émincit
    
    Cultivons amie
    Si il vaut ce nom
    Son val muet ici
    
    Indice:
    
    Si nul vice à mot
    Vu ici slame ton
    Nom c'est via lui
    Vaincu tel, omis
    
    
    
    Who am I?
    
    Here I am, Sultan!
    Vocal nightism
    Moving silica
    Io, musical wind!
    
    Here it is, musing
    Word included for life
    This unknown motive
    There, it slices you down
    
    Let's cultivate, friend
    If it's worth that name
    Its silent valley here
    
    Hint:
    
    If no word vice
    Seen here, slams your
    Name, it's through it
    Defeated as such, omitted
