The Forerunners are a fictional race of beings (not yet confirmed aliens) referred to in the Halo universe. Little is known about them, although certain things can be ascertained from hints located in the games and books. The alien alliance known as "The Covenant" exalts the Forerunners, even considering them demigods, but it is not known whether this is an earnest belief or simply religious propaganda spread by the Covenant's High Prophets. In the novel "Halo: The Flood", it is revealed that the Covenant received much of their technology from the Forerunners. Indeed, the High Prophets, who are part of the alien federation's leader caste, evolved on a planet formerly inhabited by the Forerunners.
