We're a bit on the same type of guide as for Soma's traitor in Assassin's Creed Valhalla. At the conclusion of the storyline of Jorvik, you'll be asked to assassinate The Vault — a member of the Order. The issue is that the identity of the target is to be chosen between four great personalities: Hjorr, Faravid, Ricsige or Audun.
Who is the Vault?
You'll have to tell Ljufvina — who you think is the Vault — the famous dignitary who sows discord throughout Jorvik. Audun is your man. To tell you the truth, you might as well vote for someone else, the outcome of this narrative arc will remain the same.
The rest of the characters who can be named as the traitor are significant for the rest of the scenario and will be involved in other stories that you'll probably find out soon.
As with Ivar in Bloody Path to Peace, the choice here is only an illusion. Don't worry about possible irreversible consequences like the romance with Randvi.
