It's too dangerous outside the walls
 for a city brat like you to survive.
من الخطير أن يعيش ابن مدينة
مثلك خارج الجدران
Die Welt außerhalb der Mauern
hältst du Stadtkind nicht aus!
Los niños como tú no sobreviven
fuera de las murallas.
Los niños como tú no sobreviven
fuera de las murallas.
La vie à l’extérieur est bien trop rude
pour un citadin comme toi !
Là fuori è troppo pericoloso,
un mocciosetto di città non sopravviverebbe mai.
Lá fora não é um ambiente fácil 
pra quem viveu dentro da cidade.
Городским мальчикам вроде тебя там
не выжить! Мир за стеной не такой добрый!
