The AC Valhalla Nest Ring is actually a ring that belonged to the girl’s mother, and it was stolen by a bird (most likely a raven), so the girl wants you to recover it for her.
This world event is named The Sky Thief and it is a short one, provided you know how to recover the girl’s lost ring, without getting to the nest.
So let’s get to it, together, because after we recover it there is a choice that must be made.
Where To Find The Bird’s Nest In AC Valhalla
As you can see on my map below, the girl looking for her mother’s ring is located in the south-western region of Cent.
You should be able to spot her south-west of Beamasfield.
When you get to this location, look for a wooden platform up in a tree.
The girl is standing on it, and she’s talking to the thief, that thief being a bird, or a raven if you want.
How To Get The Girl’s Ring In The Nest
After you climb the ladder, where the girl stands; read the note next to her.
It is an Apology and it was left by the girl’s mother who states that she had to break the ladder on the tree nearby because her daughter was going up that tree to see the raven’s nest.
At first sight, you’d think that this is a simple quest.
Get the ring and give it to the girl.
And you’d be right, except that there is a catch with this one because the note next to the girl comes from her stepmother.
So talk to the girl and she’ll tell you that someone borrowed the ring and then a bird stole it.
Now, getting the ring in the nest is really simple.
From the platform where the girl is located, turn around, pull out your bow and aim for the oil jars in the nest on the other tree.
Just as you see in the following screenshot.
Keep in mind that this may require several tries but it can be done, and if you run out of arrows there are more next to the note.
After you hit the oil jars, the explosion will destroy the nest and the ring will fall down.
Head to the ground and pick it up, as you see in my picture.
Once you pick it up an interesting cutscene starts and a woman appears out of nowhere.
Making The Right Choice
She is the girl’s mother and once you talk to her you’ll have to decide who gets the ring. The woman or her stepdaughter.
Regardless of who gets it, the event will end; but make sure you pay close attention to what the woman says.
Long story short, the ring you recovered belongs to the woman as she received it from her husband; however, this ring was actually owned by the girl’s mother who passed away.
Because she wasn’t able to move on with her life; the girl stole the ring from her stepmother, even though she wasn’t her.
So the correct choice here would be to return the ring to the woman and tell the girl to move on with her life. This scenario is very similar to Mae’s Last Leaf.
After you give the ring to the woman, talk to the girl and although she will be upset, she will carry on with her life.
That’s how you complete the Assassin’s Creed Valhalla Sky Thief quest; so how about helping Frode & Arne since they are close to your location?
