Assassin's Creed Origins is a 2017 action role-playing 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 38 BC, the story follows a Medjay named Bayek of Siwa and his wife Aya as they seek revenge for the murder of their son. It also explores the origins of the Assassin Brotherhood—referred here to as the Hidden Ones—and of their millennia-long conflict with 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.
