Quest Group: Ireland (Wrath of the Druids)
Prerequisites: To play this quest, you must first complete the quest A Scourging of Snakes.
This quest will begin when after defeating the leader of the Children of Danu, which will happen at the end of the quest "A Scourging of Snakes", you will return to Dublin.
Flann comes under pressure from a council of Ireland's kings.
King's Land
Ireland
Tara
Ireland
Go to Durrow where you will attend a meeting of the kings. They will demand that after what happened Flann launch an inquisition against the druids. Your answer will not matter and Flann will eventually agree to do this, which Ciara will not like and leave.
Go to Ciara's house. Eivor will try to convince her to talk to Flann again but she won't listen. She will use the gas which will make Eivor lose consciousness for a while and run away.
You will be awakened by Flann, who has also come to Ciara's house looking for her. After a while you will hear strange noises coming from Tara and when you go outside you will see that something strange is happening there.
Flann will head to Tara so follow him on your mount.
When you arrive at the location, Ciara will take control of several soldiers who will attack you and Flann. You will have to defend yourselves.
Defeat all the soldiers.
After defeating the soldiers, Ciara will take control of Flann and you will have to fight him.
You must make his health bar drop to zero and then he will regain control of himself.
Ciara will not give up and you will have to fight another battle, this time with her. Ciara has several skills. She can teleport, for example. You should avoid the green circles as standing in them will cause damage.
Ciara can also send three ghosts in your direction from time to time.
When you have taken half of Ciara's health she will summon several druid spirits who will start draining power from the Obelisk. Get rid of them as soon as possible because if you don't, a massive explosion will occur.
After you defeat her, Ciara will tell you about her powers and you will have to make a decision that will determine the ending. You must choose to kill her, which she will ask you to do, or keep her alive.
Then your character will automatically move to Bárid's grave where Eivor will have his farewell talks with Flann and Sichfrith and this quest as well as the whole main story of the Wrath of the Druids DLC will end.
