Assassin’s Creed Valhalla has a quest titled The Stench of Treachery in Grantebridgescire.
In this quest, you have to decide whether Lif, Galinn or Birna is the traitor in Soma’s clan.
Read on to find out who the traitor is in AC Valhalla.
The Stench of Treachery
This quest begins right after you’ve completed the three sub-quests to help Lif, Galinn and Birna in their missions.
Get back to the longhouse in Grantebridge to regroup and you’ll see one of Wigmund’s assistants captured.
During the cutscene, the assistant will tell you the location of Wigmund and Galinn ends up killing Wigmund. Here’s where Galinn sort of gives away his position as he claims that he’s worried the assistant will curse you. Birna replied saying Christians don’t do that.
After the cutscene, get into the longhouse to talk to Soma.
During the conversation, you can choose to talk about all three of her advisors and also clues you found around Grantebridgescire.
If you didn’t find any clues, it will be left empty.
Who is the traitor?
The traitor is Galinn as he believes in destiny more than his team.
If you choose someone other than Galinn, Soma will execute that person, be it Lif or Birna. Also, the advisors will all end up dying (as Galinn kills the other remaining person) and Soma will be left alone.
If you choose Galinn, the others will survive and more importantly, Birna will be happy with you and decides to join your crew.
