AC Valhalla traitor guide: Who betrayed Soma? 

The traitor is one of Soma's inner circle so you'll need to choose between Birna, Lif, and Galinn. Soma will begin by asking you to search around for clues and if you speak to the correct people, you'll get certain objectives to help point you in the right direction. You don't need to do any of this if you just want to take a wild guess or you already know who it is, however.

If you'd rather just know and be done with it, the real traitor is Galinn. Soma will react by executing him and Birna will join you and the Raven Clan.

If you're curious about how that conclusion is reached, talking to each of the suspects will reveal that Lif had some yellow paint stolen. If you then investigate the long tunnel that leads out of the Longhouse, you'll find yellow paint splashes all along its length—to the point where the Saxons landed in their boats.

There's no way of knowing who stole the paint at that point but exploring along the river bank to the north will lead you to find some destroyed longships along with Lif's poetry. Make your way even further north from here and you will discover Galinn's longship which is painted yellow, signalling the Saxons to attack the clan's home.

Finally, if you set off to the west of the river, you'll soon come across a Saxon camp, and you'll need to deal with a group of enemies that are found here. Once they've been taken out, search the camp to find a letter from the Saxon Wigmund that tells his men to leave the ship painted yellow alone. A pretty (yel)low move from Galinn, huh?
