Contents[show] HistoryEdit The Traveler's origins are unknown. When it arrived, humanity first discovered it on Mars. It sparked a Golden Age of humanity that allowed humans to migrate from Earth to colonize other planets within the Solar System. Some speculate that the Traveler is a large vessel; others believe that it is a sentient being or artificial intelligence and some may even consider it a deity. As of yet its true nature is unknown. The Traveler is credited with humanity's survival during the Collapse of the Golden Age. After the Traveler sacrificed itself to save humanity, it remained floating not far from the Earth's surface, and became silent and dormant. The City was built in its shadow and under its protection, where its inhabitants are temporarily safe from the threat of the Darkness. The Red WarEdit Dominus Ghaul, leader of the Red Legion, attacked the City and trapped the Traveler inside a barrier, cutting off its Light from the Guardians.[1] Ghaul absorbed some of the Traveler's Light to fight the Guardians, but he was defeated. Ghaul resurrected as a cloud of pure Light. Instead of choosing Ghaul, the Traveler broke its barrier and obliterated him, releasing a pulse that reaches throughout the entire galaxy.[2]
