Mask attached to a ceremonial hat.
A Hollow once fought valiantly with this mask, but feared the fading of her self, and implored a comrade remembered her name.
Perhaps that is why this gentleman's mask is named after a woman.
Can be obtained from Pickle Pee in return of an Vertebra Shackle. (only once per NG)
Note that in Dark Souls 3, you do not need to reload to complete the trade. Dropping the item inside the nest is sufficient.
