first of all sangnielos is under arbiter control with unsc backing
prophets vanished
elites hate brutes
dr. halsey hates the unsc(more oni) not humanity she will defend humanity its why she created spartans her life work
elites would get destroyed by the unsc (unsc infinity)
and jackels are out for themselves as a whole same with all the other races except maybe hunters
halo 5 should have a precursor (uncourupted gravemind) and more forerunners come back i know they apparently died to kill the flood but some like the master builder (if alive didnt finish book) werent so noble and survived
the precursors could come back telling the humans they have passed the test and in due time must take on the mantle but first must end war with the covenent remenants, and pursue the surviving forerunners who failed the mantle so long ago. combat will be between the infinity fighting the covenant in pursute of the other half of the map, and a new ship ifinity's sister ship "UNSC Victory" or maybe "UNSC Human Spirit".
but based on the trailer thats not happening
ONI would terminate cortana they dont care
halsey is a civilian not oni
there are still spartan 2's and threes they were traped on onyx with halsey if u read the book
