Eliminating Moths

Young traveler……. Oh, should I call you a hero now? Haha. Aren't you a modest person. All right. Let's settle for 'brave warrior,' then, because we have a problem that requires the strength of a brave warrior, such as yourself.
Well, the problem isn't that serious, actually. Most of the Deribelle Guards are too exhausted from the campaign to eradicate monsters in the outskirts of Deribelle, and I fear that redeploying them would lead to great casualties. Therefore, we are in need of your help, of a brave warrior's help, that is.
Your task is to hunt <HFFFA7272>15 Giant Silver Moths<HFFFFFFFF> at the <HFFFA7272>Border of Rucklia Amae and the Spores of Joy<HFFFFFFFF>. It shouldn't be too difficult, but it might be tricky as the monsters have been quite active lately. So please be very careful when you carry out this task. Then I wish you luck, brave warrior.
May the courage of a true warrior and the strength of the Elementals be with you.

Good job. Thanks to you, our guards could really rest up. But still there's one thing bugging me.
