After building Seer's Hut in Assassin's Creed Valhalla, you'll be able to enter in symbiosis with Havi — a personality from Asgard. In his bosom, you'll no longer ride a horse but a deer and the mystical surroundings will bring to light another side of the legend of Eivor.
There is little to pick up in the area, but the resources to be caught should at least allow you to visit the island in its every nook and cranny.
Apart from a flyting battle, the famous offering altar mentioned above and the cairn, there are only events. There are all very simple to complete in this zone. Completing everything shouldn't take you more than 30 minutes — except for the 30 Ymir's Tear Stones.
The only wealth of this area is the Ymir's Tear Stones, which is used only for the Offering Altar in the area. It will take you some time to gather it all together — but you don't have to do everything at once.
Once Valka the Seer has joined your ship, a potion to return to Asgard will also be offered to you.
