Mered was a merchant who operated his stall, Mered's Wares, in a market located in the ruins south of the Great Sphinx of Giza. In 48 BCE, the Medjay Bayek of Siwa was directed by Apollodorus to Mered, who had information regarding the Hyena, a member of the Order of the Ancients. Mered was given a payment of drachmae, and revealed to Bayek the Hyena's real name to be Khaliset. In exchange for information about Khaliset's whereabouts, Mered asked Bayek for a favor, requesting him to retrieve his horse which he claimed to have been stolen by some of his customers from a hideout south of the market.
Accompanied by several of Mered's men, Bayek was able to retrieve Mered's horse, bringing it back to the market. Honoring the deal, Mered revealed to Bayek that Khaliset lived in a cavern in the hills west of the pyramids of Giza and spent her time roaming the desert collecting silica.
