In the mid-1st century BCE, Khaliset served the Order by gathering silica for them in the ancient tombs of Giza, as silica had special properties and could be used to power the Isu technology sought by the Order.
Eventually, however, she went rogue and began keeping the silica for herself, prompting Taharqa, a fellow member known as The Scarab, to write her a letter questioning her lack of contact with them. At some point, she had begun to study the ancient symbols in the Isu vault beneath Khufu’s Pyramid and began to learn how to use the technology, believing that it would ultimately enable her to resurrect her daughter, Eshe.
In 48 BCE, the Medjay Bayek of Siwa tracked Khaliset to the Great Pyramid of Giza, where he found the Isu Temple, Eshe’s sarcophagus, and evidence of Khaliset’s attempts to resurrect her, before Khaliset herself appeared, furious that Bayek had disturbed her daughter’s “tomb”. He chased her through the pyramid’s tunnels, eventually succeeding in killing her after a dramatic confrontation in the middle of a sandstorm outside the pyramid. As she laid dying, she told Bayek that her only regret was not being able to bring her daughter back; Bayek told her that what she found was not meant for mortals. Her body was later eaten by the very hyenas she trained.
