Eeyoo Sekedoo Aat

Eeyoo Sekedoo Aat is an Isu vault located along the Nile in Egypt. It is connected to the tomb of Smenkhkare, an ancient Egyptian Pharaoh 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, where he activated the vault's pedestal, which in turn started a recording made by the Isu after the Great Catastrophe intended for Layla Hassan, who was reliving Bayek's memories in 2017.
