Gilfir says, "Thank the Hearthmother, you have arrived at the most dire of times! The forest needs your aid, CHARNAME." "The Vaelwyn have corrupted Fullmoon Spring, causing the Okami that drink from it to shift out of phase with nature itself. As guardians of the forest, we must do something." "Before dealing with the Okami, we will need to purify the spring. Collect stalks of Kiyo grass from the field to the north, and I will make a purifying potion. Return to me when you have the stalks."
