Quest Realm: Vanaheim
This quest can be unlocked during Chapter 6, The Reckoning.
If you remember, Lunda has asked Kratos and co to find the eponymous Mysterious Orb
.
Depending on where you start this quest, things might work out a little differently in terms of docks and navigation. Also remember that this quest will have to link into Freya’s Missing Piece in order for you to be able to progress properly, in that you must (seemingly) complete Freya’s Missing Piece first in order to access the Orb’s location.
The instructions pick up after finishing the aforementioned Freya quest.
After completing Freya’s Missing Piece, tracking the Mysterious Orb quest using OCR, navigate to a dock by boat, possibly entering a new area whilst doing so with dialogue about Seidr being nearby.
Then nav assist onwards, find an interact on your left and hit it to pick up the orb. On PS4, this was a real pain and I kept finding an interact for an oil pot dispenser instead, but the one you’re looking for appears to be nearer to the boat itself.
Then, as instructed, navigate back to the boat (though this might take a while to find the interact prompt as nav assist breaks a little here, it’s a comparatively small area so you shouldn’t have too much trouble moving around to find it. Yes, I know this is not ideal.
As a tip, if you hear a locked item whilst nav assisting, turn 180 degrees and run forward. You should then see an interact which is hopefully the boat.
Orb retrieved, you should actually not complete this quest before the end of chapter 9, as having it still trackable means you can also complete Guiding Light using that as a starting point, amongst other elements.
If you wish to return the orb immediately however, row your way back to land, where Lunda will be awaiting you. Grab anything you missed at the warchest, then trigger the optional conversation to hand in the orb to her, as well as taking any other ones you haven’t heard yet.
After this exchange, the quest is complete and you can return to whatever else you’ve been doing in-game.
