John-117, adrift on the back half of the UNSC Forward Unto Dawn for over 4 years since the Battle of Installation 00, arrives at Forerunner Shield World 000, Requiem. He finds Covenant remnant leader Jul 'Mdama's fleet in orbit, and after a brief battle, John, along with the rest of the Forward Unto Dawn and many Covenant ships, fall through an opening in the world and crash onto the interior surface.
During his investigation of the shield world, John and Cortana pick up a signal from the UNSC Infinity, who arrived after detecting Cortana's distress signal from the Forward Unto Dawn. Attempting to locate the Infinity, John accidentally releases the Ur-Didact, an ancient Forerunner Warrior-Servant. The Didact then successfully traps the Infinity in Requiem's gravity well and forces the ship to crash-land onto the interior surface.
John regroups with the Infinity and helps fend off an attack while the crew repairs the ship and gets it back into orbit. John and Cortana chase the Didact, but he escapes to Gamma Halo and recovers the Composer. They then follow him to Earth, where the Didact uses the Composer on the surface before Cortana sacrifices herself to allow John to stop the Didact.
