When spoken to, the Grey Mourner talks about her dead lover, the daughter of the Traitor Lord, and requests The Knight to take a Delicate Flower to her grave, located in the Queen's Gardens. This flower will break if the Knight uses Fast Travel, teleports with the Dreamgate, or takes damage.
Amongst its hateful kin that did deny our union, that did reject che's... outside-ness. She doesn't suppose?... Nahlo, Nahlo. Could che' ask? Could che' burden? Le'mer, woulds't you, coulds't you deliver gift to her grave? The gift is, maybe small?
But the trek is long. She rests amongst her kind near our Queen's lush refuge. Would such a thing be done? Che' asks perhaps impossible things? Mad things? For Le'mer to take up such quest would be a kindness che' has near forgotten.
Her grave lies in the middle of the Queen's overgrown estate. It is surrounded by her kind, who will not look kindly on your trespass. Take care Le'mer. My hopes I place upon you and my fervent wish that this small solace may come to pass.

...I suppose, che' does have one more flower though. But Le'mer! This one is equally sacred and equally fragile. Where'st one to accept such quest, it must become mel'precious heart. Would such a thing be again be tried?

If you were to get hurt again whilst carrying it, or did to attempt ride those jolting transit beasts, this one too shall be destroyed. Though my faith in one has been...challenged, my hopes are still with you Le'mer.

After acquiring King's Brand
The Grey Mourner is found residing in a house in a secret area in the east of the Resting Grounds.
- The Grey Mourner is heavily implied to be Ze'mer, one of the five Great Knights, due to the large nail in her home, and comments about serving under the Pale King when shown the King's Brand.
- Her speech pattern uses the word "Le'mer," which is very similar to "Ze'mer"
- Her physical figure also fits the Dung Defender's statues of the other Knights, along with the silhouette in the White Defender's arena.
- What's interesting about this theory is that other characters encountered who have known the Dung Defender all comment on the player wearing the Defender's Crest, but not the Grey Mourner.
- The Grey Mourner is a backer NPC created by Xun Zhao, confirmed by Team Cherry in a reddit comment.
