The Darkmoon Knightess is also called the Brass Knight, and she wears the Brass Armor.
If anyone has played Armored Core 4 Answer, another FromSoft game, you would know of a character named Wynne D Facion, who is called the Brass Lady and pilots a mecha very similar in design to the brass set. on top of that, she uses a blue energy blade that looks very much like the R2 of the estoc. We all know how FS likes to reference their own games, so out of affection for the characters in both games I call her Wynne.
