From what i read one of the reasons the forerunner lost the war against the flood is because they were very peace oriented and eventually removed all their weapons from their world…that, and their leader defected to the covenant because he went rampant.
I’m just asking these questions to get a little more info. I know somewhat about the Halo universe
No, the Forerunner lost the war because they took too long to recognize the flood as a threat. The Forerunner were almost warmongering, as they constantly attacked societies who were too close to being as good as them (for religious reasons, but…). Read the Mendicant Bias section for more info. The Covenant has nothing whatsoever to do with everything else going on in these questions. No offense, but I think you might need to read a bit more.
The Librarian is a lifeshaper, a Forerunner protector of life. She was the wife of the Didact, and worked on a plan to preserve life during the firing of a Halo Array. She convinced the Master Builder to protect her precious humans on the Halos, as well as form the Shield Installations. She gathered samples of all the sentient life in the Galaxy (those who would die for hosting the Flood), storing them on the Ark as well. She, in her great wisdom, installed geas into her humans, so that the knowledge of their ancient warriors would not be lost. She died on Earth during the Halo actitivation, to keep the Flood from getting to the lesser ark through the portal. After Primordium, it is believed a geas or some similar technology preserved her through the ages up to modern times.
During the Flood’s assault on Forerunner civilization, Mendicant Bias was the ultimate compound ancilla (forerunner AI), designed to perfectly counter the flood’s attacks. However, he was convinced by that time period’s Gravemind (flood intelligence) to betray Forerunners, and he did that by entering Rampancy (madness) willingly… Later on, he ended up on a massive Forerunner keyship/dreadnought, the same one at the center of High Charity. He was awoken by the Covenant discovery of Humanity, before being short-circuited (something like that) Later on, the Keyship was brought to the ark, where he repented his acts and tried to make up for it, by theoretically saving the chief (that is what it sounded like). Because the Ark was apparently seriously damaged, it is believed he is dead, or
Installation 00 is the Lesser Ark, as seen in Halo 3. Installation 04, or Alpha Halo, is the first Halo discovered, in Halo CE. The Ark can activate the Halo Array from outside the Milky Way, keeping you safe. It also builds replacement Halos. I assume you know what the Halo Array is, so I feel no need to describe their exact process. I will do it, of course, if you wish.
The Didact is the Leader of the Forerunner Armada. He commands the entire Army, and led the majority of assaults in the Human-Forerunner war. His Wife is the Librarian, who he worked with to save humans, on the Halos, Shield Installations, and the Arks. He transferred his consciousness into the body of Bornstellar Makes Eternal Lasting, who became the didact in all but blood. He was the one finally activated the Halos, and vanquished the Primordial, learning the truth of the Flood’s ‘cure.’ His eternal foe was the Lord of Admirals, his human equivalent, Forthenco. It was under his commission that Mendicant Bias was wrought, and later Offensive Bias.
Offensive Bias was created to eradicate the Beggar After Knowledge, Mendicant Bias. His mind was more narrowly focused, to prevent a second Mendicant, and he successfully scored impressive victories over the Flood. However, the Flood simply had too many forces, large numbers, and so they resorted to the final solution, the Halo Array. It is believed Offensive was either deactivated or destroyed, but the truth is still unknown for now.
