Created by Roberto, and expanded upon by Chronarch. [quote]1) 6 of the 7 Halo rings are still primed and ready to fire - a shadow that will forever loom over the Halo universe as long as it's unresolved. [url=http://www.youtube.com/watch?v=ArbPF58V-Co&feature=youtu.be&t=3m34s]Frankie states in the Halo A-Z video that "we never diffuse that fuse"[/url]. This is picked up on in Halo 4, as the primary mission of the Infinity before the Requiem campaign was to find the other Halos and study them for decommission. 2) The Gravemind tells us that defeat at Installation 04B at the end of Halo 3 only delays his return. This is picked up in the narrative of the Forerunner Saga, as we know from the end of Primordium that the Precursors (in the form of the Flood) are returning. 3) Mendicant Bias virtually screams to the player that the Chief's story is not done, informing us that: 4) The Forerunners are not dead... 5) ...and that the path to the Forerunners is "fraught with peril", suggesting a new threat to confront. 6) No explanation whatsoever was given to these mysterious new beings referenced by the Didact called the Precursors. This obviously formed the basis of Greg Bear's Forerunner Saga, and which we now know is feeding directly into the Reclaimer Saga. 7) Nor was any explanation given as to what "following in Their footsteps" means in Halo 3's Terminals when the Didact started talking about the Great Journey he and the other surviving Forerunners will go on after he fires the Halos. 8) Therefore, the Great Journey [i]does[/i] exist, but has been misinterpreted by the Prophets. What is the Journey, and what is the significance it has? 9) Mankind has yet to uphold their destiny as the guardians of the universe (as mankind's destiny is the entire thematic point of the series, not continuing the story would mean voiding the relevance of the franchise as a story). This forms the thematic basis for the Reclaimer Trilogy, as the name itself implies. 10) We do not know if humanity can survive the inevitable tensions between the Covenant client races, the Elites, and themselves. 11) We did not know (at the time, until Cryptum) what made humanity so special and worth saving in the eyes of Librarian. She said that we held the answer to many secrets, something which Halo 3's main narrative NEVER addresses but constantly slaps us in the face with because it shows us that humans are Reclaimers. 12) Cortana, who holds the largest wealth of Forerunner knowledge in the universe aside from the Forerunners themselves, is slowly drifting into insanity. How can anyone claim that Halo 3 provided any kind of satisfying closure when we spend the whole game building up to her rescue only for her to be discarded and left to rot into insanity half an hour later? 13) And finally, Master Chief, the selected messenger of Medicant Bias, is drifting near an unknown Forerunner world at the very end of the game.
