[quote][b]Posted by:[/b] MGTrey People need to learn literary mechanics. In Halo CE, you could make a case that Cortana was at the most a co-protagonist. The story is told from the Chief's POV at all times, but she's right there almost the entire game and gives directives. And a fair bit of plot exposition comes from her as well. Halo 2, the Chief and the Arbiter were the stars of the show. Cortana was a B-tier character along with Johnson and Keyes. Halo 3 was all Chief, even though the Arbiter had a bit of shine. So, if you add that all up, Chief would clearly be the main character. Almost everything of worth in the trilogy happens to him or because of him, and the vast majority of the story is told from his point of view.[/quote] I know literary mechanics. I also know that there are endless ways an author can tell a story. Believe me, I am a writer. But onto the topic at hand... (this is from another thread) I'm just working off of personal theory, not known fact. I think that with the addition of Forerunner "knowledge" and tech - as seen in Halo: Reach - she became more of a Forerunner construct and less of a UNSC construct, or a hybrid of the two. It's possible that she has the ability to keep going indefinitely, "forgetting" or deleting irrelevant information as needed. She is quite possibly the most important piece of equipment both and the most important individual figure in the Human-Covenant War, it isn't surprising to be honest. Without her, the Master Chief would have been nothing. Without her, Noble Six and Noble Team would have had no purpose. She is the common denominator and ultimate catalyst of the entire Halo series.
