Walkthrough
Follow the quest arrow, battling your way through large Jotun. Once you get to the shrine area, there will be several wolves who will turn from ally to foe. Destroy these as well as the few Jotun. After all foes in the area are cleared out, double click on the Volfen Spirit. Receive the blessing and then replace a skill on your bar with it.

Activate it and use Volfen Bloodlust. This will allow you to track Svanir the Nornbear. Follow the marker to a large room-area, and destroy foes in your way. In upper right corner you will find a corpse and Jora will speak, making the Nornbear appear. Attack it until it disappears.

Track it again with Bloodlust, and follow the path back the way you came. Follow the wall until where the star is. If you don't notice it, there will be a small path up on the right. Go up it and toward an arch made of ice. Do NOT pass the arch, first because you don't need to and second there is a group outside of it. Jora should begin speaking before you get to it anyways. The Nornbear will appear and you will need to attack it until it disappears yet again.

When it disappears, you will need to head down the little path. Start heading back toward the first place you battled him. Continue tracking him with Bloodlust. Once you get to the tunnels with icy walls, make the first left and follow the path. When you get to the top you will see the Nornbear as an ally, and he and Jora will have a brief dialogue. Attack and kill the Nornbear. Once he is defeated, there will be a cutscene in which Jora will finish the job, saying this was the only way for it to end. After the cut scene, you are teleported back to Sifhalla.
