The Assassin's Creed series is one of Ubisoft's most popular franchises, growing its fanbase and community since its original launch in 2007. The most recent installment, Assassin's Creed Valhalla, released Nov. 10, gave the franchise its best year since 2012 when Assassin's Creed III launched. With 12 titles in the series thus far, Assassin's Creed has a vast lore spanning several historical eras with a rich cast of characters. One of the less explored areas of lore is what the actual creed in Assassin's Creed is.
