Assassin's Creed Origins is a 2017 action role-playing video game developed by Ubisoft Montreal and published by Ubisoft. It is the tenth major installment in the Assassin's Creed series, following 2015's Assassin's Creed Syndicate. Principally set in Egypt, near the end of the Ptolemaic period from 49 to 43 BC, the story follows a Medjay named Bayek of Siwa and his wife Aya as they seek revenge for the murder of their son, and explores the origins of the millennia-long conflict between the Hidden Ones—forerunners to the Assassin Brotherhood, and the Order of the Ancients—forerunners to the Templar Order. The framing story, set in the 21st century, follows a new character, Layla Hassan, who relives Bayek and Aya's memories using a modified Animus device.
