Halo Timeline

While Cortana's Created armies work to subjugate the galaxy, an isolated conflict between a long-lost crew and a new enemy emerges — and it may end up impacting the entire Halo universe at large.

As conflicts throughout the galaxy continue, a new force emerges — one that is lead by a friend that was thought to be dead, though she no longer is who she once was.

As the Master Chief moves forward following Cortana's apparent passing and the Didact's defeat, the UNSC Infinity returns to the planet Requiem for further investigation and analysis.

Just when it looked like all hope was lost for humanity, the Covenant began to tear itself apart due to a devastating civil war that would eventually lead to the faction's collapse.

While the rest of the galaxy attempts to heal from years of conflict, the Master Chief must put everything on the line in order to stop the Didact from ending humanity's future.

As the Prophet of Truth races to The Ark in order to activate all of the Halo rings, it's up to the UNSC and the Sangheili, led by the Master Chief and the Arbiter, to stop him ... all while trying to thwart the efforts of the Gravemind and the Flood.

The Human-Covenant War, at long last, has ended. However, the old feuds and new discoveries that make up the Post-War Era ensure that the tired, battered galaxy will not yet be able to rest.

After the firing of the Halos, the galaxy began to rebuild. Forerunner artifacts left behind from the past were in abundance — and two species, the Sangheili and the San'Shyuum, went to war over a disagreement about how they were to be used.

Following the birth of the Covenant, the new Sangheili-San'Shyuum coalition explored the galaxy searching for Forerunner artifacts — and along the way encountered several species that they would come to integrate into the alliance.

After a complete defeat at the hands of the Forerunners in the ancient times, humanity grew to rebuild and once again thrive on Earth — and beyond. This is the story of the rise of humanity in Halo's current era.
