Vulcan Manor (Elden Ring)

Spoilers ahead, so if you don't want to unravel the plot, don't read on.

At Vulcan Manor, you can enter Tanith's house and do their errands. Talking to some NPCs in the castle got some interesting information. So, it turned out that Raya actually has a different appearance and her real name is Zoroyas. She will give a clue to a secret passage in the castle (you can find it without her guidance).
Communicated with her and with Tanith. And in the end, Zoroyas disappeared, and Tanith asked for a potion of oblivion.
I found a girl in a castle, in a closet where lava flows. You can go down there by the stairs in the window, or by running along the lava.
More details on its location -
Spoiler If you are in this territory for the first time, then you need to go through a secret passage in the living room (first room on the right), through the church (temple of the prison city), along the roofs, to another temple - Igli, where there will be a battle with the Skin boss. To the second floor of the temple with the help of a lift, jump from the balcony to the street, climb up the stones among the lava and slip past the maiden into the window of the turret. Going further, look at the windows on the left, in one of them there will be a staircase down. Jump down and go to the turret where Zoroyas will sit.


She will ask you to kill her. You can kill, you can give a potion. I didn't do anything, just canceled the conversation. Went and killed boss Rickard. Got his great rune. Tanith after the boss said she would leave the estate. And she really disappeared. Went to Zoroyas and she's gone too. In its place was a letter and the amulet of Dedikar.
Spoiler


So here it is. Who can do other things? Tell me what would happen then. And judging by the letter, the girl did not kill herself, but went somewhere. Can she be found somewhere?
