''"For I certainly found beauty everywhere,For the colorful flowers and singing birds, they all left me, Salvation bringing me here, to a vast plateau of dark rock and nature...This is most unusual.But in spite of all these,it was the safest place, and even the farhest...I wonder if the Covenant Know that we are here"

"I wonder if he knew anything...If he lied to me, if he only wanted to make me feel better...."''

-Halo: The Covenant Chronicles Capter.2

Cortana is a female Smart A.I, A.I Of the UNSC Pillar of Autumn ,later, the UNSC Course of Clad

Cortana began her service on 7 November, 2549, and her Fnish-date is still unknown.Cortana was given to Masterchief John-117, and became a great help to him.

She was one of the most important figures in the Human-Covenant war, and served as John-117's partner in various combat missions as well as serving as the A.I. for the United Nations Space Command Halcyon-class light cruiser UNSC Pillar of Autumn, the Orbital Defense Platform Cairo Station and later, the UNSC Course of Clad. In addition, she held vital data pertaining to the Halos, including the Activation Index from Installation 04.

Battle of Installation 04
"Halo doesn't kill Flood. It kills their food. Humans, Covenant, whatever - we're all equally edible. The only way to stop the Flood is to starve them to death. And that's exactly what Halo is designed to do: wipe the galaxy clean of all sentient life."

— Cortana reveals the true purpose of Installation 04 to John-117.

After emerging out of slipspace, the two discovered a ring shaped world called "Halo". Unfortunately, Covenant ships had followed them, and the fighting continued. Controlling the UNSC Pillar of Autumn's defenses, Cortana managed to destroy four Covenant targets over Installation 04 before the ship's weapons were disabled by Covenant boarders. Following the Cole Protocol, Captain Jacob Keyes, the ship's commanding officer, prepared to abandon ship. Because the Cole Protocol forbade the capture or destruction of any A.I. construct, the Master Chief was charged with protecting Cortana from the Covenant. It was around this time that the Chief learned that Covenant forces had successfully captured Keyes and taken him to the Truth and Reconciliation. The Master Chief rescued Keyes, who left to infiltrate what appeared to be a Covenant weapons cache located in a swamp. The Chief and Cortana used the Silent Cartographer to locate and enter Halo's Control Room, where Cortana was uploaded to Halo's core systems. When the Master Chief asked her how Halo could be used against the Covenant, she hinted that the Halo wasn't what it seemed to be. She also learned that the "weapons cache" Keyes was attacking was really a Flood Containment Facility. She stayed in Halo's systems sending the Master Chief to find Keyes. After the Chief encountered the parasitic Flood for the first time, he was convinced by the Forerunner Monitor 343 Guilty Spark to activate the Halo. During this time, Cortana apparently absorbed as much data as she could about Halo from its control systems. 343 Guilty Spark helped the Master Chief retrieve the Activation Index. The Chief, intent on using the Index to eliminate the Flood, returned to the Control Room and inserted the Index into the Halo's control panel. Luckily, Cortana stopped the activation sequence and removed the Index's data, informing him of the true purpose of the Halo Array. Cortana's actions saved all life in the galaxy from total annihilation. At that point, 343 Guilty Spark, seeing that the duo had no intention of returning the Index, tried and failed to kill them to retrieve it. After enduring prolonged engagements with the Covenant and the Flood, Cortana realized that detonating the Pillar of Autumn's fusion reactors would destroy the Halo. Unfortunately, the reactors could only be activated using codes stored in the now-infected Captain Keyes's Command Neural Interface (CNI). The Master Chief retrieved the CNI, and he and Cortana managed to detonate the reactors despite interference from 343 Guilty Spark. The two escaped the resulting explosion by racing through the ship's crumbling superstructure in a M12-LRV to a hangar bay, where one remaining Longsword fighter was still berthed. Climbing aboard with the Flood right behind them, they barely outran the blast, and watched through the viewports as debris from the reactor breach destroyed the remains of the Halo ring.
