SUMMARY
Master Chief Petty Officer Spartan John-117 arrives back on Earth by slowing away on the Forerunner Dreadnought that left High Charity in the closing events of Halo 2. He meets up with the Arbiter Thel 'Vadam and Sergeant Johnson and proceeds to reconnoiter with UNSC forces. Admiral Hood and Commander Miranda Keyes devise a plan to attack the Portal at Voi which the Covenant were trying to activate. John-117 successfully breaches the Covenant anti-air defenses, allowing the UNSC forces in the area to attack the portal directly, but they are ineffective. The portal is activated, and the Covenant forces use it to travel to the Ark.
Before another plan can be devised, a Covenant ship infected by the Flood arrives at Voi, and the UNSC and forces under Thel Vadam are forced to contain the threat. In the process John finds a message from Cortana declaring a threat to Earth from the Flood Gravemind aboard High Charity. He decides to travel with Commander Miranda Keyes aboard the UNSC Forward Unto Dawn and Thel 'Vadam's fleet through the portal to the Ark to stop the Flood and stop Truth from activating the Halo array.
On the Ark, the UNSC allied forces find Truth trying to activate the array, and a new Halo being constructed in the Ark's forge. They decide to fire the unfinished Halo to destroy the Flood and all of Truth's forces on the Ark, turning 343 Guilty Spark into an enemy again. John manages to recover Cortana and fire the Halo, destroying the Flood, but also leaving him adrift aboard the rear half of the now derelict Forward Unto Dawn.
The Battle for Earth was a large-scale space, air, and ground battle between the invading Covenant forces and the UNSC Home Fleet on and around Earth at the end of 2552.
The Great Schism was a conflict between the forces loyal to the Covenant, led mostly by the Jiralhanae, and the Sangheili, beginning on November 3rd, 2552 and continuing off and on until the Rule of the Created in 2558.
The Battle of Installation 00 was a major conflict between the forces stationed aboard the UNSC Forward Unto Dawn and Arbiter Thel 'Vadam's Fleet of Retribution, and the Covenant fleet loyal to the Prophet of Truth.
The Voi Memorial was erected in March 2553, marking the end of the Human-Covenant War and to remember all who were lost during the conflict.
