[Halo 5 and 6 - Story Plot - Another brainstorm]

 

What is known:

FORERUNNER

--the Didact is for certain the Ur-Didact (Halo 4 didact)

--the Librarian is dead (supposedly) - Chant-to-Green took her place as Lifeshaper

--the Iso-Didact was still alive after the firing of the Halos (Bornstellar)

--343 Guilty Spark was Chakas

--there was a forerunner colony in another galaxy far from the reaches of the Halos (the most probable place the forerunners fled too after reseeding the galaxy/ Path Kethona/ supposedly destroyed)

--that 6 of the original 7 Halos remain (from the Lesser Ark)

--that a city of nearly 2 million people had been composed (end of Halo 4)

--the Ur-Didact's interest in Cortana (...."this evolved ancilla")

 

HUMAN

--Master Chief was/is the only Spartan 2 left alive

--humanity has begun cataloging all the halos and forerunner artifacts in their galaxy

--humanity has also begun to integrate their technology with forerunner technology

--Dr. Halsey was kidnapped by the Storm Covenant, obtained the Janus Key. The key was split in two: half was kept by Dr. Halsey, the other was given to Spartan Gabriel Thorne

--Cortana supposedly died/ended service after the destruction of the Ur-Didact's ship

--Cortana was created/found by Dr. Halsey on Reach, in an ancient forerunner complex, housing a crystal

--may I also point out that from what I've read, and from the games that have been released thus far, that MC is the only spartan I have seen with an AI companion?

 

FLOOD

--even a single flood spore can house the memories and intellect of every flood being before it

--originated from powdered Precursors

--used as an act of vengeance upon the forerunner race

--no cure - even though it is eluded that humanity had a cure, this was later discredited when it was revealed that the flood had simply receded from human space, not infecting them

--supposedly destroyed at the end of Halo 3

 

COVENANT

--Arbiter has returned to rebuild his home world

--Storm Covenant was/is a covenant fleet sent to Requiem after being founded in 2553 after Halo 3

--now in the possession of Dr. Halsey and part of the Janus Key/ Storm Covenant

 

NEW ASSUMPTIONS:

Presuming 343 would not have a major villain die off so quickly, also presuming they would not have him take such an interest in Cortana as to then kill them both off, my other assumptions about the next halos are as follows:

 

HALO 5

Introduction is Master Chief putting on his new suit, all sad and gloomy about not having Cortana.

Refuses another companion AI/ not offered one.

 

***Arbiter introduction could be here, as he is preforming a diplomatic mission to earth or has requested aid from the UNSC against the Covenant Remnant***(1)

 

-Master Chief is sent on an mission to retrieve Dr. Halsey

--sent with Infinity to retrieve Halsey and the Janus key, with minor disruption

----this mission's intel came from an enemy ship (Covenant) presumably Halsey wishing to escape

----the transmission sent from the ship also requests the other half of the Janus key be brought

----Goes to rescue Halsey and discovers she is not a captive, but a leader of the Covenant resistance, only after bringing the other half of the Janus key

----MC is captured (for a moment) and Dr. Halsey uses the Janus key to discover the All Record's location

----shortly after, the UNSC Infinity bombards the Covenant fleet holding Halsey and MC

----Halsey, though injured and dying, says something to MC, confirming she was in fact still working for the UNSC and was 'playing the part'

as it was the only way they were going to get the information stored in the Janus key

----Halsey dies, the Janus key is destroyed, but MC has the coordinates, and he escapes the destruction

 

Infinity uses the coordinates MC has and finds the All Record, along with the Covenant, and the Flood.

----mission is to use the information Halsey provided on the All Record and find the information the Librarian said would propel humanity forward

----MC navigates through the Covenant and forerunner enemies, going through various missions and leads, trying to determine what information he is looking for

----MC then begins to understand forerunner glyphs (something that the librarian did perhaps?)

----the Flood begins its quest anew, and begins converting the Covenant Remnant

----MC fights through the forerunners, covenant, the flood, eventually finding something interesting

----an active forerunner facility marker, located in deep space (another galaxy perhaps), where there appears to be a data center for the Composers (as there is more than one)

****sometime during this part of the game, MC has a breakdown, feels he is unable to continue and begins to freely express his sadness over the loss of Cortana (I want him to cry, but that may not happen)

 

MC travels to the forerunner facility/ planet/ shield world/ etc.

----discovers there are more composers, the Didact is in fact alive, and so are many other forerunners

----in a final cut scene, the MC is captured by the Didact and held in stasis. he is then stripped of his armor, piece by piece

----in the epilogue, Cortana will be speaking, and the cut scene will show MC with Cortana saying "I found you."

 

HALO 6

--Cortana is alive and well, and is actually human (to a degree)

--The Didact used the composer to bring prometheans forth and Cortana came out almost human, a perfect replica of a young Dr. Halsey

--basically Cortana survived the Composer, something not even forerunners have been able to do, and came out human (almost human)

****mentioned before by some people, I have mentioned as well, it was noted that this would be a possible outcome, and so I found it interesting enough to post

 

/////////

will post more when I think about it, there are a few things to discuss, so discuss whilst I think up a plot for Halo 6 that fits with the above story line. 

 

First of all that you had some of that wrong which just really bugs me (not judging ) but what i found that was wrong was:

-The chief is not the last Spartan ll because at the end of Halo Glasslands, the UNSC recovered 3+ Spartan ll's and I believe a couple Spartan lll's so maybe e could be because the Spartan ll's are getting old and could've died sometime beofre the events of Halo 4

-When you say cataloging all Forunner technology, i'm assuming you mean all FOUND technology (see what i mean? Little thing like THAT bug me. Still not judging)

Its only two reasons but i felt that I had to say the first one. And Master Chief isn't the only Spartan that had an A.I. Naomi-010 had the A.I. BlackBox.
