What is the extent of Guardians, and just how many are active/dormant? A question that I have is, what if the Forerunner structure beneath Reach’s Castle base also house a dormant Gaurdian? It could be a cool return in the story that we go back to Reach, to activate the Guardian that is solely controlled by the Chief. And maybe ultimately the Chief becomes a Guardian, leading to the notion that Spartans never die. It could be a fitting end to the Chief, so that he does not die, but transfers his physical form. Or something like that. Just an idea.
Good idea, except the part where chief becomes a guardian, if that was the end for the chief I think I would shoot myself
