Strange Symptoms

As those who've watched me for a long time know well, I rarely get angry. There's only one occasion I get angry. I resent those who destroy this forest and who bring violence.
Ah, are you asking why I am angry? I recently came across something strange in the forest. Some of the Harpies don't seem normal. Some of my friends told me that they looked as if being addicted to some kind of dark power. So I've been investigating this. I appreciate your help.
Don't worry. It won't be hard. Please, get <HFFFA7272>2 Rare Feathers<HFFFFFFFF> for me. I need to look into what's in them. If possible, please kill <HFFFA7272>Windwing Harpies<HFFFFFFFF> in the <HFFFA7272>Southwest part outside Ellore<HFFFFFFFF> and use <HFFFA7272>Collecting Skill of Nível 3 or higher<HFFFFFFFF>.

Everybody is busy. I didn't mean you're not, but we cannot afford to do this. So please kill <HFFFA7272>Windwing Harpies<HFFFFFFFF> in the <HFFFA7272>Southwest part outside Ellore<HFFFFFFFF> and use <HFFFA7272>Collecting Skill of Nível 3 or higher<HFFFFFFFF> to get <HFFFA7272>2 Rare Feathers<HFFFFFFFF>.

Oh, you got them. Thank you! I hope to find the answer when I examine these feathers. If you're interested, too, please stay.
