Dhaunayne says that her family lived in Sadrith Mora. Now she has a great grandson. High Elves live for centuries, particular high born ones like them. That must have been ages ago, maybe in the second era or earlier. What was a family of High Elves doing in Sadrith Mora when it wasn't part of the Empire?

If Dhaunayne has connections to House Dres, why and does Marethi from Dawnguard come into this somehow?
