[ EU ] Spartan 117 , The Master Chief , has defected to the covenant .

In the year 2552, Noble Six failed to reach the UNSC *Pillar of Autumn*. Cortana was never delivered, and without her guidance, the *Autumn* was easily captured by Supreme Commander Thel'Vadamee. Under the Prophets' behest, the cryopod holding the Master Chief was refitted to interface with Covenant systems aboard the planetoid station *High Charity*. There, the Oracle of *High Charity* recognized the hardware implanted into S-117, and began interacting with him, trying to explain the reality that the Prophets mistook as religion. After convincing the Master Chief of his importance, the Oracle segmented a portion of himself into the Spartan's neural interface. 
 
 After 3 years, the Master Chief was released from his cryopod, aware of the threat looming over both humanity and the species forming the Covenant. The Sangheili, being a true warrior species, recognized the way the Master Chief carried himself, and V'rtha'Fahi was eventually tasked in evaluating the `` Demon'' as a possible member of the Covenant. 
 
 Several months passed, and the Demon was soon recognized as an merited member of the Sangheili. Attaining the rank of Commando, the Demon was assigned to the *Purity of Spirit*.
