The year 98,395 BCE is a year in the distant past.
- Circa 98,395 BCE, the Librarian undertakes on a mission to study the origins of the Flood in the satellite galaxy of Path Kethona. In Path Kethona, the Librarian and the crew of her explorer vessel, Audacity, discover a world with a population of primitive Forerunners. On this planet, she learns the truth about the Precursors' disappearance ten million years earlier: the Forerunners rose up against their creators and annihilated them in defiance of the Precursors' choice to pass the Mantle on to humanity. The Librarian would keep this information to herself at the time, fearing that the Builders in control of the Old Council could potentially use it against her or the Didact.
