The Glow

The Glow was the name given by the Forerunners to a mysterious realm outside of conventional space, composed solely of photons. According to the IsoDidact the Forerunners had explored this realm before 97,445 BCE. The Ur-Didact was able to analyze the Glow to calculate relevant data in normal space around Charum Hakkor.

The Librarian referred "the great Glow" as reference point for before life existing in the galaxy.
