This quest begins once you have pledged to Jorvik from the alliance map in your longhouse at Ravensthorpe. Hytham has informed Eivor that Jorvik is home to at least 3 prominent members of the Order of Ancients. Eivor, encouraged by the presence of old friends in Jorvik (Hjorr and Ljufvina), sets out to investigate the city.
Find Hjorr and Ljufvina in Jorvik
You’ll find Jorvik far to the north of Ravensthorpe, and you’ll reach it most quickly by longship if you don’t have a fast travel point there already. In particular, you should go to the docks at Jorvik in search of Eivor’s friends. Once you’ve docked, head northeast to the Trade Depot, where a cutscene will begin (this is directly opposite the docks). During the cutscene you’ll have a few dialogue options with the dockmaster. Choose as you wish here. The dockmaster will inform you that both Hjorr and Ljufvina can be found in a manor surrounded by flowers. You’ll find this north of the docks, as shown below.
When you approach the manor you’ll discover that it’s known as the Councillor’s House. When you enter, you’ll find that the place has been ransacked, with neither Hjorr or Ljufvina anywhere to be found. You should now examine all the evidence left behind from the event, starting with the scattered scrolls on the ground floor, the blood upstairs, the broken barrel outside, and then follow the blood trail southeast from the barrel, to a body. After that, continue following the trail to the nearby building. A cutscene will follow.
Follow Ljufvina to the Royal Hall
During the cutscene you’ll find Ljufvina. Respond to her dialogue in whatever way you want, then follow her to the royal hall, where Hjorr might be found. As you make your way to the royal hall, you’ll need to avoid the guards by blending into various activities with Ljufvina as you move through the market. These will involve sitting on a bench and putting Eivor to some craft work. When you reach the bridge, continue to follow Ljufvina with your cloak on.
When you reach the royal hall, a cutscene will begin. You can respond as you want to the king, there will be no real consequences. After the audience with the king, follow Hjorr back to Ljufvina and speak with her to discuss the next steps. The quest will end after this conversation.
