Sam writes: “In a way, Assassin’s Creed Valhalla is as much about being a badass Viking kicking butt and drinking ale, as it is about immersing yourself in Dark Ages England. But it’s not just about the history, but more about capturing the mindset of the people at the time. Because of that, the series has become well known for its blending of history and mythology. Real-life locales and people are brought to life alongside the monstrous beasts that the people of the time really believed in, from Medusa to the Minotaur of Assassin’s Creed Odyssey, to the Egyptian Gods like Anubis and Sobek in Assassin’s Creed Origins. ”
