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.
