During the Grantebridgescire story arc in Assassin's Creed Valhalla, players must assist the Viking leader Soma in reclaiming her settlement. A central part of this questline involves solving a tense mystery to identify a traitor within her inner circle. Determining who betrayed Soma requires careful investigation of physical clues and character motives across the region.

The Investigation Behind Grantebridgescire

Soma relies heavily on her three trusted advisors: Birna, Lif, and Galinn. After an unexpected Saxon attack forces her clan out of Grantebridge, she realizes someone provided passage to the enemy. Eivor is tasked with gathering evidence to uncover the turncoat before taking final action.

Interrogating town residents and searching the longhouse reveals critical details about the night of the siege. Each advisor offers a distinct alibi and perspective on their fellow clan members. However, personal biases and conflicting stories make it tricky to rely solely on conversation.

Uncovering the Key Clues and Yellow Paint

The most compelling physical evidence begins in a secret escape tunnel beneath the longhouse. Splashes of yellow paint mark the path leading toward the riverbank where the attackers landed. Lif reveals that his supply of yellow paint was recently stolen, pointing toward internal foul play.

Following the waterway into the Fens leads to a fleet of abandoned longships. Among these wrecks lies a single vessel freshly painted in yellow, which belongs directly to Galinn. Additionally, a note recovered from a nearby enemy camp orders Saxon soldiers to spare any ship wearing yellow paint.

Why Galinn Is the True Traitor

Galinn's underlying motivation stems from a fanatical obsession with his own personal visions. He believed that ultimate greatness was destined for him alone rather than sharing power alongside Soma. This twisted desire for leadership led him to strike a deal with the Saxon leader Wigmund.

While Lif held mild resentment toward Soma and Birna harbored secret romantic feelings, neither acted against the clan. Galinn alone possessed both the physical evidence against him and a dangerous ideological drive. Accusing him brings the true culprit to justice and clears the innocent advisors.

Consequences of Your Final Choice

Presenting the correct evidence to Soma results in Galinn being executed immediately for his treason. This outcome secures stability for Grantebridge and earns Soma's lasting gratitude. Furthermore, Birna expresses relief and requests to join Eivor's settlement as a loyal crew member.

Choosing the wrong suspect produces tragic results for Soma's inner circle. Accusing Lif or Birna leads to an innocent execution while Galinn remains free to strike again later. Selecting Galinn guarantees the best possible narrative outcome for your alliance network.
