The chests of the norns of the Midgard of God of War Ragnarok begin to be distributed from the small piece of scenario that you will accomplish alongside Freya when you go to see the norns. All in all, there are 4 Chests to nab in the area and they should be easier to find than the ones in Vanaheim .
Well of Urd
During the A Word of Fate chapter, when you arrive at the third destination indicated by the dogs, you will come across the chest during your ascent. These are 3 torches to light with your Chaos Blades. The first torch is just to the right of the chest, for the second climb thanks to the hooks of the mountain, it will be right on the wall above. Finally, for the last one, you just have to fall and go down one floor to top it.

Rowers
You will have to continue the Curse of Sigrun quest to find this norn chest, for which you will have to activate 3 bells quickly. By following the normal course of the quest, you will recover a second half-key to open the safe further west of the kingdom. Right next to the object, start by turning the debris around by firing a sonic arrow at the barrel . Go back to the first part of the room, near the wooden chest to be at the epicenter of the 3 bells: start with the one on the left, then the one you just freed and finally the one behind you.

The treasure
This chest will be settled at the same time as the last part of the Curse of Sigrun quest. Three torches to light: the first can be seen just above the closed door when you move the shield to the left with your chaos blades. The second is in the rocks above you on the upper level of the area when you scaled Tyr's Shield. For the last, it will be on your right when you are inside. Please note that you will have to shoot a few sigil arrows to reach them.

The Lair
By following the Animal Instinct side quest, you'll drop into the lair area southeast of the kingdom for the final stage, where you'll have to eliminate a bunch of marauders including their particularly pissed-off leader. Once you have cleaned up, you can light the 3 corner torches and to do so, you will need the bombs placed nearby. First turn on the one that asks you to explode the golden debris to reach it at the back of the room. The second is in view behind the red brambles on the left of the chest. As for the third: when leaving, be careful on the left, at the very back. The torch is inaccessible even with a bomb because you can't throw it high enough for it to hit that portion . You will therefore have to compensate for this by accumulating several purple arrows at the right level so that the thrown bomb hits the bucket, which will then light the torch itself.
