Master Chief and Cortana accidentally free the Didact and he briefly returns to assert supremacy over humanity, though he is foiled by the pair, resulting in Master Chief initially believing Cortana dead in the attempt. Cortana's survival through the Domain leads her to break with the UNSC and assert a new hegemony over the galaxy, with artificial intelligence (the "Created") in control. After two years of a scattered war between Cortana and the UNSC, Cortana attacks the Banished, a mercenary organization largely led by the Jiralhanae race. The Banished win the resultant conflict, terminating Cortana and battle the UNSC for control of Zeta Halo.
