Normally there is a monitor floating about the technology it is watching and wanting to activate it, probably because they are mostly bored and glad for the company lol
His voice makes an appearance during the mission where you have to protect the spirit of fire as it goes through the sheild world. But other then that there was no where abouts of him.
What for real! I’m going to have to check it out lol 
Easy to miss sounds very robotic
Lol I can’t believe I missed that 
busy preventing the flood from collecting more biomass
The lone monitor all alone 
During the campaign mission or the cutscenes?
During the mission. You can only hear him though.
Time to dust off the game that is Halo’s Irony.
And he does outlive the installation. Check out Smoke and Shadow and Renegades
So what’s he doing right now I wonder
hopefully not like Intrepid Eye, who was playing God to see which factions would win to obtain the mantle of responsibility….that’s the second forerunner A.I to say this, the other was the one in charge of the absolute record but I thought the Librarian said humanity was to obtain the mantle? Why did they not follow orders?
Well, those other Forerunner AIs weren’t necessarily in service of Lifeworkers. Clearly neither the Warrior Servants, Builders, not the head of the Ecumene Council were exactly pro-Humanity
Oh well that makes sense, so much for advance alien species, they couldn’t even decide who would obtain the mantle 
Well indeed, but there were clear disagreements there. The huge and climactic events by which the Forerunners ‘seized’ the Mantle from the Precursors were seminal in the development of Forerunner society
But then why did the flood attack humans if they were to be chosen by the precursors the whole lore is so confusing now I will need to re read all the novels for clues
Well the Flood was formed from the corrupted remains in canisters of dust/powder which ancient humans and/or San’Shyuum applied to pheru pets so I’m not sure we can read too much into the actions demonstrating any ‘plan’ on the part of the Precursors
So your telling me some animal on alien dust tried to wipe out the galaxy! That’s hilarious lol 
I mean, the dust was fundamentally part of the plan for the Precursors, but something definitely didn’t go right with the plan.
I know but it’s pretty hilarious, I just hope when we fight the endless they have a better back story since apparently they are worse then the flood
