Rya

Rya is an NPC in Elden Ring. She serves Lady Tanith and the Volcano Manor as a scout that searches for potential recruits. You can first meet her in Liurnia of the Lakes, where she is looking for help to get her necklace back from Blackguard Boggart. Once you progress far enough in the Volcano Manor assassination quests, you can find Rya in a previously empty room of the manor, now in her real form, the man-serpent Zorayas. When given the Serpent's Amnion, Rya will begin to question her origin and disappears from the manor entrance. You can find her near the elevator at the temple where you fought the Godskin Noble. You'll have to make a choice on whether or not you want to let her live, follow her request to kill her, or give her Tanith's potion to erase her memory.
