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 Lake Mareotis. 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.
Shortly thereafter, Bayek visited the temple, where he was reunited with Menehet, an old friend of his and a priest of Sekhmet. After laying down an offering, Bayek played a game of hide-and-seek with Menehet's children before returning them back home.Returning to Menehet in the courtyard, Bayek came across an angry tourist confronting Menehet regarding the sale of false religious icons in the market. Bayek was able to discover the source of the false icons from a rogue merchant and dismantled their operations.
