Around 48 BCE, the vault was visited by the Medjay Bayek, who activated the vault's pedestal and witnessed a recording made by the Messenger. Dated one hundred and five days after the Great Catastrophe, the message displayed was intended for Layla Hassan, who was reliving Bayek's memories in 2017.
Circa 38 BCE, a traveller looking for treasure removed an artifact from the Desheret Desert complex, which activated the complex and created illusions of undead soldiers. Bayek investigated the area upon hearing rumours of strange lights in the desert, and fought through the illusions. At the traveller's behest, the Medjay-turned-Hidden One sought to recover the artifact from the traveller's camel, which had run off. After finding the artifact and fighting through yet more illusions, Bayek returned the artifact, but was ambushed by more undead soldiers.
