1. Collect all the amber shards
By the time you receive the quest, one of the ten members of the Children of Danu will already be dead (The Wren you killed in the "Potion of Blood" quest) so you will have to locate and kill nine more.
A few more members will be killed as you progress through the main story of the Wrath of the Druids expansion, and they will be these:
The other members of the Children of Danu you will need to locate based on clues (you can also go straight to the places where they should be, as long as you know where) are:
1.1. The Wren (Niamh, the poet)
Note: She is dead but I posted information about her to have all the information on the Children of Danu members together.
The first clue comes from the conversation with Ciara and Deirdre in the "Potion of Blood" quest.
The second clue is in the abandoned cottage on the shore outside Port Auley It's the Note Found in Port Auley.
The third clue is near the ritual stone located on a small island in Lough Gara found near Rathcroghan. It's the Note Found Near the Great Stone.
These clues will allow you to pinpoint the location of The Wren.
1.2. The Cursed (Sétnae, druid of the mists)
1st clue - Objects found on The Wren.
2nd clue - From Conversation with Ciara, at the beginning of Into the Fog quest.
3rd clue - From a Conversation with a Captive, later during the Into the Fog quest.
You will locate and kill The Cursed at the end of the quest "Into the Fog".
1.5. The Oak (Eogan mac Cartaigh)
You will get clues about The Oak as you progress through the main storyline, and you will confront him during the quest "A Scourging of Snakes".
