Yuria of Londor is a key NPC for reaching the Hollow Lord ending. She only appears in the Firelink Shrine if you use Draw Out True Strength from Yoel of Londor five times to acquire five Dark Sigils. This must be done before reaching the Catacombs of Carthus, as Yoel passes away when you do.

If Anri dies early or Yoel dies before you draw out all sigils, Yuria leaves and the Pale Shade of Londor invades in Farron Keep and Irithyll Valley. Defeating it in both places causes the Pale Shade armor set to appear in the room where Yoel and Yuria reside.

Yuria also becomes angered if you heal the Dark Sigil, or you kill the Pilgrim of Londor in Irithyll Valley before the ceremony is complete. While Yuria is friendly, the Pale Shade of Londor appears as a White Phantom in Farron Keep and Irithyll Valley.

If you progress all the way to the end game after the ceremony with Yuria still friendly, both her and the Pale Shade leave White Phantom signs for the final battle. Defeating the final boss with her still alive causes her to leave her armor and weapon where she stood in Firelink Shrine.
