Seshem.eff Er Aat is an Isu vault located in the Black Desert in Egypt. It is connected to the tomb of a Nomarch, who had his final resting place built on top of the complex's remains.

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 ninety-three days after the Great Catastrophe, the message displayed was intended for Layla Hassan, who was reliving Bayek's memories in 2017.
