On this page of the Assassin's Creed Valhalla guide, you will find a detailed description walkthrough of A Wise Friend quest.
The Ravensthorpe Settlement is growing day by day, and an old friend of Eivor is looking for a new home there. You will get access to this task after reaching level 3 of the settlement.
Rewards: 1700 XP.
Meet the new arrivals at the docks.
Go to the harbor in the settlement and meet with Valka - the oracle and a new resident of the Ravensthorpe Settlement.
After the cutscene, take one of Valka's luggage and walk her to her new home. The trip will take some time because Valka will make stops to talk to other residents of the settlement.
During the conversation with the Oracle, you will learn that once you have completed the construction of her new home, you will be able to work on Eivor's visions.
