In Assassin's Creed Valhalla, players encounter one of the game's earliest and most compelling detective quests during the Grantebridgescire arc. As Eivor, you must help Soma, the leader of the raven clan's new allies, identify a traitor among her three closest advisors: Birna, Lif, and Galinn. Uncovering the truth requires careful investigation, gathering clues, and interviewing locals across the region.

Gathering Clues in Grantebridge

To solve the mystery, players must explore the secret escape tunnel located beneath the longhouse in Grantebridge. Inside the tunnel, you will find yellow paint marks left behind by the traitor to guide the Saxon invaders. Following the riverbank leads to a abandoned longship that was recently painted yellow, providing crucial physical evidence.

Evaluating the Suspects and Their Motives

Interrogating the three captains reveals distinct personalities and potential motives for treason. While Birna expresses unrequited devotion to Soma and Lif focuses on ship construction, Galinn exhibits a dangerous obsession with personal glory and prophetic visions. Checking the yellow paint supply in Lif's workshop confirms that his paint was recently stolen, pointing the finger away from him.

Identifying the Real Traitor

Piecing together all the evidence reveals that Galinn is the true traitor who betrayed Soma to Saxon forces. Galinn believed that Soma stood in the way of his ultimate destiny, which he saw in visions of grand power. Presenting the correct evidence to Soma results in Galinn being brought to justice and secures Birna as a loyal crew member for your longship.

Consequences of the Choice

Making the correct accusation strengthens your alliance with Soma and keeps her inner circle united moving forward. Accusing the wrong person, however, leads to tragic consequences for innocent advisors and weakens your bond with Grantebridgescire. Careful investigation ensures the best possible narrative outcome for Eivor's journey across England.
