The Ark was damaged during the events of Halo 3. You can read Hunters in the Dark for more info.
Spoiler:
ShowThere is no Monitor in charge of taking care of the Ark anymore. Maybe Isabel was tasked with running parts of it.
Yea the flood is still around, so is the Diadac in a battle 343 failed to tell us about, ONI thinks he is composed, but he nor the MC can be, also there are a few precursers and The primordial. So who is really the true reclaimer?Its not Cortana as she might think. The Ark is outside of all rings, protects all from them too and out of the Milkyway as well, Halo rings are only for that, yea the Arks outer core is melted but what more is there?
The Diadac is gone and irrelevant we should just let that one go. Even if he decided to come back Cortana controls all the AI forces. At best he would be able to get a bunch of ex-covenant into thinking he is a God but you can't wage war without ships.
Sorry my friend, cant speak for 343, but he isnt gone, not by alongshot. they(the DIADAC) were also split the iso n the(brain freeze). He is clearly alive and clearly saved Cortana, Id almost bet Cortana is his Ancilla too, how else would she know about the watchers, the domain, she was dead for all practical purposes. you see all this in Halo4 except the unknown battle with the MC were he compozed the Diadac, the Diadac cant be compozed, same as the MC, The flood will be in HW2 fact! Wa this the primordial or the Diadac using a biological weapon he can now be cured of which is the Flood. The MC watched Cortana die as in dead, yet here she is. how? Only answer posible, the Diadac fixed her.
No bro these are all just your opinions. Where exactly has it been stated that a the Diadac can't be composed?
If you say because he is a Forerunner that's like saying a gun salesman can't be shot because he sales guns. Unless you can back it up with an explicit lore reference that says otherwise can be composed just like any other living thing.
No they arent, they are straight from the lore as written. If they were mine, I would not have done it that way. The flood HW2, 343 answered that, ok,;~}Everything can be found on this forum, sorry but true. Please note all halo MC games are numbered1-4, but Halo 5 Guardians, The Diadac met with the last one an ancient, who accepted that the Forunners held the mantle and gave the location of all Guardians, now the Diadacs Change made him imune to composing, like the lib did for the MC. research for yoursef as I did for over a month, also the Ark is very specail, so 343 says HW2 is now real Sparton time, the flood spores were protected but they need one central brain that can span not just the milky way but universe, is from out of the galaxy just like the ark is now. can the flood make a new gravemind on the ark? Or will the primordial do it, or as Cortana says, all life and the flood is considered life it seems in the forrunner archive, even a pic of the flood in the ark is here on the forum.So is this a misunderstanding? So now the Diadac accessed the domain and the Guardians with Cortana and forrunner key. Thats were its at my friend, but it all came from 343, the game or was on the forum w\links
