Retaliation

The cargo boxes you recovered were actually stolen by the Redflag Sentries. They hid them where the Fire Ghouls are and got them to guard the boxes. If we don't do anything about it even when we know what they did, there is no assurance that an incident like that won't recur. So I want to get back at them, to make them pay the price for their transgression.
Do you get me? What you must do is to eliminate <HFFFA7272>Redflag Sentries<HFFFFFFFF> on the <HFFFA7272>Death Plain<HFFFFFFFF> and use <HFFFA7272>Collecting Skill of Level 5 or higher<HFFFFFFFF> to obtain <HFFFA7272>25 Rare Bells<HFFFFFFFF>. Those are what they treasure the most, so taking the bells will make them think twice about touching our cargo again.
May the Elementals have vengeance on those who betrayed you.

Good. This will be enough to make them scared. They won't touch our cargo again. Good job. May there be spirit's revenge to those who turn their backs on you.
