Captain Kurtiz:
I'll tell you again. Please don't let them use Aden as an exit. Go to Nightmare Kamaloka and defeat Tracker Mino, Ill-fated Princess Sola, Fallen Angel Ariar, and Confined Princess Sirra, in that order. Lastly, defeat Betrayed Dark Rider.
The monsters in Nightmare Kamaloka won't be easy to defeat, so make sure to take your friends with you. I won't say thanks until you come back safe and sound.
