— Marcus Fenix to KR One-Nine's pilot, after spotting the Riftworm
Fourteen years after Emergence Day, during the Battle of Ilima, KR One-Nine was assigned to evacuate Delta-One from a rooftop ambush in the Ilima sinkhole. After successfully evacuating Delta-One, One-Nine was hit by debris from the Riftworm's tunneling, causing it to spin out of control into the Riftworm's jaws. It then crashed inside the Riftworm with only Delta-One surviving the crash, though Pvt. Benjamin Carmine would later die inside the Riftworm.
