If you try to talk to Tharayya under the following conditions
1. A character has recently completed Frostvault
2. A new character that has completed Volenfell but has not done either Wrathstone dungeon
She is missing the dialogue that explains why she is there. She will not tell you about what happened to Volenfell.
