The Halo Timeline: A Journey through Time

The Halo timeline takes us through the creation of the universe, the evolution of sentient life forms, and the events that led to the first Halo game. Let’s explore the various timelines that have been introduced in the Halo Universe.

The Precursors-era Timeline

The Halo Universe revolves around ancient races known as the Precursors, whose technology led to the creation of the Forerunners. The Forerunners, in turn, created the Halo rings to protect sentient life from the Flood, whose primary goal was to consume all life in the galaxy. The Precursors-era timeline spans billions of years and is shrouded in mystery.

The Forerunner-era Timeline

The Forerunner-era timeline starts when the Forerunners became the dominant power in the galaxy. The Forerunners discovered the threat of the Flood and sought to contain it, leading to the creation of the Halo rings. The Forerunner era spans 100,000 years and ends with the activation of the Halo rings by the Forerunners, which wipes out nearly all life in the galaxy, including the Forerunners themselves.

The Human-era Timeline

The Human-era timeline starts with the emergence of intelligent life on Earth, leading to human colonization of other planets in the Milky Way. In 2525, humanity’s first contact with the Covenant, an alliance of alien species, starts the Human-Covenant war, which spans over 27 years. Eventually, the war ends with the defeat of the Covenant, and humanity sets forth to reclaim its place in the galaxy.
