Yamu was a village located south of Alexandria and on the west coast of Lake Mareotis in Egypt. During the 1st century BCE, the village housed a temple dedicated to the Egyptian goddess of Sekhmet.
In 48 BCE, the Medjay Bayek passed by the village during his journey to Alexandria from Siwa. There, he came across a woman by the name of Ebio, who sought his help to look for her husband Klaudios, who had took a boat to the ruins near the lake. When Bayek returned with Klaudios, he discovered Ebio's claim as Klaudios' wife to be a fraud and helped him to eliminate her two bandit brothers.
Bayek later met Beka, an old man whose Book of the Dead was stolen by bandits from the Necropolis hideout. Beka requested Bayek to help him recover the book before being urged by his daughter to return home.
Beka later died of natural causes, and his body was brought to a mummification temple by his daughter. Bayek later returned with the book, placing it beside the old man's body.
