Biography
During the Battle of Installation 04, Cornelia helped to settle on a cliff side at Installation 04 so that ODSTs Major Antonio Silva and First Lieutenant Melissa McKay could set Alpha Base. She later warned Silva about an incoming Covenant attack on the base, comparing it to the French cavalry charge at Waterloo, which annoyed a focused Silva. Following the securing of Alpha Base, Cornelia interfaced with the base's anti-air turrets to help John-117 after the Covenant returned to the base searching for the SPARTAN-II. During her attack, she was able to destroy three Spirits and two Phantoms.

Following the capture of the Covenant CCS-class battlecruiser Truth and Reconciliation by the surviving ODSTs and Marines, Cornelia stood at the side of Lieutenant McKay when Silva became rampant and wishing to leave the ring, where she stated they should await for every last xenomorph on the ship to be exterminated, or else it would lead to an outbreak on Earth. When the Major did not comply, McKay cut all communications from the ship's engines, and the Truth and Reconciliation crashed on the ring's surface, killing everyone inside, including Cornelia.
