The game’s narrative is structured around "Sagas," individual story arcs tied to different regions of England. Unlike its predecessor, Assassin's Creed Odyssey , which focused heavily on a central linear plot, Valhalla uses these regional alliances to build the player’s power and settlement, Ravensthorpe.

: While Eivor is not a traditional Assassin, the game integrates the "Hidden Ones" (the precursors to the Assassin Brotherhood) through side quests. Players must find six codex pages scattered across England—in cities like London, Winchester, and York—to uncover the history of the order in the British Isles. Exploration and Gameplay Mechanics

: The game bridges the gap between different eras of the franchise. In the Crossover Stories , Eivor meets Kassandra , the protagonist of Odyssey , connecting the Viking age to the broader Isu lore. Critical Reception

: Several quests require players to gather clues and identify traitors. For instance, in the Stench of Treachery quest, identifying the wrong traitor among Soma’s inner circle leads to immediate narrative consequences.

Valhalla leans further into the RPG elements introduced in previous titles while refining the "Raiding" mechanic, where players lead Viking longships to attack monasteries for supplies.
