In 522 BCE, the throne of Persia was usurped by Gaumata. Cambyses attempted to march against the usurper, but died shortly after under disputed circumstances. After a few months, Gaumata was eventually overthrown by Darius.
Almost 500 hundred years later, a group of explorers discovered a site in the Isolated Desert which they believed to be the remains of Cambyses' army. Due to the harsh environment and the number of casualties suffered, the explorers later abandoned the excavation site. The site was later discovered by the Medjay Bayek in around 48 BCE, overridden with hyenas.
