The town of Ermina turns out to be a city for fish, where the whole town is submerged in water during high tide. The moment the party mentions Water God Dragon, the fish turn hostile.
But our mission is to 
defeat the Water God Dragon.
Aber unser Ziel ist es,
den Wasserdrachengott zu besiegen.
Pero nuestro objetivo
es vencer al Dios del Agua.
Mas nossa missão é derrotar
o Deus Dragão da Água.
