A Minami plot was behind the massive wyvern attack on Saphir.  To stop the plot, Nyanta attacks the train carrying the Minami general alone.  But he's faced with the sorcerer he defeated long ago, the man who trapped Serara in the far north, Londark.
The weak use their weakness as their weapon!
und die Schwachen ihre Schwäche!
¡Los débiles usan su debilidad como arma!
et les faibles, de leur faiblesse !
I deboli usano la propria debolezza come arma!
Os fracos usam a fraqueza como arma!
а слабые претворяют свою слабость в оружие.
