The player takes on the role of a Medjay named Bayek and his lover Aya, as they work to protect the people of the Ptolemaic Kingdom during a time of widespread upheaval: the Pharaoh, Ptolemy XIII, struggles to maintain his rule whilst harbouring ambitions of expanding his kingdom; his sister, the recently deposed Cleopatra, begins marshalling loyalist forces to launch a counter-coup against Ptolemy; and frequent incursions into the Kingdom by the Roman Republic under the command of Julius Caesar lead to fears of an imminent invasion. Bayek's role as a Medjay brings him and Aya into contact with the secretive forces manipulating these events and into becoming the first Assassins.
