There’s only one Nornir chest in this location. You need to find three seals and destroy them in any order to be able to unlock this chest.
The first seal is right right behind it, on the rock outcrop.
The second seal is located behind the round ruins to the north but you can only reach it by peeking over the edge where the second binding shrine was located as shown below.
The third seal is located behind the metal gate near the nornir chest; however, it can only be lifted from the other side. Take the lower path and get past the round ruins. Continue to the cave and you’ll find the seal beside the metal gate. Destroy it then lift the metal gate to access the chest.
