Quest 663
From Ethene
Requirements: Demon Swordsman current job.
Speak to Agatha in the Sword Bar again, who will ask yo uto help a girl suffering from darkness. She informs you that she can be found in a house southwest of Gran Zedora Kingdom at C-7.
After a touching moment we find out the girl is in tears because she's lost a precious belonging of hers. Head outside to the T. Gran Zedora Region in pursuit of it. You can find the item around C-5.
Tip: Be wary of the mobs near here if you aren't in a strong party. Some will give even a party of 60's a rough fight.
