Khemu (unknown – 49 BCE) was the son of Bayek and Aya. During his life, he enjoyed hunting with his father and spending time with him. Khemu's best friend in Siwa was Chenzira, who sometimes came hunting with Bayek and Khemu.
Khemu was named for Kemet, the ancient name for Egypt.
He was conceived while his parents were in the desert – hiding from an assassin who was trying to extinguish the last remnants of the Medjay bloodline – where Sabu, Khemu's grandfather, had trained Bayek for several years. After killing Sabu, the assassin discovered that Aya was pregnant and so tried to kill her and Bayek in order to accomplish his mission on behalf of Raia, a member of the Order of the Ancients. The two lovers managed to eliminate their would-be murderer, however and Khemu was born months later.
Life and death
Unlike his friends and family, Khemu was shown to be scared frequently and doubted he would be able to live up to his father legacy as a Medjay.
In 49 BCE, the Order of the Ancients kidnapped Khemu and Bayek, bringing both of them to the Siwa Vault beneath the Temple of Amun. Believing Bayek to have knowledge regarding the vault and how to open it, the Order attempted to interrogate the Medjay for answers before being interrupted by the arrival of the pharaoh Ptolemy XIII.
Khemu used the confusion to free his father, who attacked the members before being subdued. Amidst the confusion, Flavius physically manipulated Bayek (whom tried stabbing him) into stabbing his own son, who succumbed to his wounds shortly after. After his death, his body was buried in a tomb in the Mountain of the Dead.
Khemu's death led his parents on a quest for vengeance against the Order of the Ancients. By 47 BCE, most of the Order's members in Egypt have been assassinated, with only Lucius Septimius and Flavius Metellus, Khemu's murderer, remaining. While Aya went after Septimius, Bayek pursued Flavius to Cyrene. Bayek confronted the Roman Consul in the Temple of Zeus in Cyrene and, despite Flavius taking advantage of an ancient relic of the gods, killed him. In the void, Khemu asked his father to let go of him before he rubbed the feather against Flavius, putting him to peace and satisfying Bayek's quest for vengeance.
- Despite his short role and small life, his death led to a series of events which resulted in the official core founding of the Hidden Ones, a secretive cabal which later evolved into the Assassin Brotherhood.
- The necklace worn by Khemu (later worn by his father) would later serve as the "template" from which the Assassin insignia was derived.
