The Halo franchise takes place in a fictional science-fiction universe, where there are four major factions players encounter or control. Halo's story has 26th century humanity, led by the United Nations Space Command (UNSC), caught in a war with a genocidal alien coalition known as the Covenant. In the video game Halo: Combat Evolved, a lone UNSC ship surrounded by Covenant discovers a mysterious ringworld known as "Halo". The massive installation was built by an enigmatic race known as the Forerunner, who have long since disappeared for unknown reasons; the Covenant worship the Forerunner as gods. During the course of the game, players discover that the Halos were built by the Forerunner as a weapon of last resort against the Flood, a parasite which is driven to consume all sentient life. The Forerunner were forced to activate the Halo network, killing themselves and any potential Flood hosts, in an effort to starve the Flood to death. In Halo: Contact Harvest, it is revealed that the Covenant leadership discovered that humanity was in fact descended from the Forerunner, and decide to commit genocide in order to suppress the truth.
