Ton is surprised. However, she learns the ring from her great-grandmother that she always wears holds a major secret.
The moment I arrived, I was robbed 
and my friend vanished in this dangerous city!
سُرقت لحظة وصولي واختفت
!صديقتي في هذه المدينة الخطيرة
Kaum bin ich hier, werden meine Freundin
und ich in dieser gefährlichen Stadt ausgeraubt.
¡Me robaron en cuanto llegué
y mi amiga desapareció!
¡Me robaron en cuanto llegué
y mi amiga desapareció!
e nel momento in cui ci metto piede, vengo derubata
e la mia amica sparisce in questa città pericolosa.
Foi chegar e fui roubada, e a minha
amiga sumiu nesta cidade perigosa!
Стоило приехать, как меня ограбили,
а подругу похитили! Какой опасный город!
