His first chronological appearance is in "The Fall of Reach", where, as a young Lieutenant, he accompanies Dr. Catherine Halsey on her mission to screen possible SPARTAN-II Project subjects. In 2534, Lieutenant Keyes plays a pivotal role in saving a million insurrectionists' lives from Covenant forces. By 2552, midway through "The Fall of Reach" Keyes is commander of the "Iroquois", a UNSC destroyer. Keyes is promoted to Captain after he singlehandedly defeats four Covenant ships about to attack a human colony by performing a maneuver later named the "Keyes Loop." When the "Iroquois" is recalled to the human bastion Reach, a Covenant tracking device aboard the ship alerts the Covenant to the planet's existence, and they proceed to attack the colony. As the planet is glassed by the Covenant, Keyes follows Cole Protocol, which leads his new ship, the "Pillar of Autumn" to Halo. There, Keyes leads a guerrilla insurgency against the Covenant, until he is captured and assimilated by the parasitic Flood. His daughter is Miranda Keyes.
