How to Find and Kill The Wren (Lady Niamh)
You’ll encounter The Wren as part of the main story, during Potion of Blood.
Find the Clue at Port Auley
The process of finding The Wren will be familiar if you’ve hunted Order of Ancients members before. You’ll need to find specific clues which lead to more clues, and eventually to the cultist themselves. The first clue can be found near the Port Auley trade post. More specifically, you’ll find it in a building on the coast just north of the trade post. When you enter the building, you’ll see the clue on top of a pile of sacks. Read it to learn more about where you need to go next.
Find the Clue at the Ritual Stone in Lough Gara
The next clue can be found near the ritual stone at Lough Gara, near Rathcroghan, just south of Port Auley. Once you’ve read this clue, the location of The Wren will be revealed.
Assassinate The Wren at Rathcroghan
Once you’ve read the clue at Lough Gara, you’ll be able to track the location of The Wren at Rathcroghan, located just south of where you found the clue at Lough Gara. Be sure to mark The Wren’s location from the Children of Danu menu, then find her within Rathcroghan and take her out. You’ll need to confirm the kill before you can move on, but once done all you need to do is return to Deirdre to complete the quest.
