Question: who do you play in assassin's creed origins
Answer: The player takes on the role of a Medjay named Bayek and his wife 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 while 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 .
