and if you accept her invitation, 
you lose your life.
.وإن قبلتِ دعوتها فقدتِ حياتك
Und wer sich auf ihr Spiel einlässt,
verliere sein Leben.
y si aceptas, pierdes la vida.
y si aceptas, pierdes la vida.
Ceux qui accepteraient
en mourraient.
Chi accetta l'invito, perde la vita.
e se você aceitar o convite
dela, você perde a vida.
И те, кто откликаются на её зов, умирают.
