In every Halo story in the first Trilogy, there were three enemies: The Covenant, the Sentinels, and the Flood. That being said, I believe this pattern will continue. It has been released that there is no Flood presence in Halo 4. That could just leave the Sentinels, but where is the ‘ancient evil’ 343 said was being released upon the Universe? There are three ancient races that are currently known to the Halo Universe: the Flood, the Forerunners, and the Precursors.
Thee Precursors were the rivals of the Forerunners. Where Forerunners lead in technology, the Precursors made up for in other aspects. Among these was a cure to the Flood. One senario is that they learned of the Forerunners’ plan to activate the Halo array. they then hi-jacked one or more Forerunner Shield worlds to ensure their survial. One of these includes Requium. After 100,000 years, a human, ancestor to the Forerunners, shows up in their home. Fearing a Forerunner uprising, they decide to try to wipe out Humanity.
The Forerunners were a more peace-seeking race. After the appearance of the Flood, their actions were solely on preventing its spread. They then enabled the Halo array, supposedly sacrificing themselves to stop the Flood. Another senario is that they simply lost their presence in the Milky Way. Any Shield Worlds in the Galaxy were too far from the Ark, so they built more outside of the Galaxy, close enough to the Ark to be a mere few days in under-power, a few years without. After Halo’s activation, could no get back to the Milky Way because the technology for their portals was lost. They DID, however, retain information uplinks to the Halo array. When they began getting activity and noticed the sudden loss of information. (i.e. the destruction of Installations 04, 00, and 04 again), they became furious with the humans. When they learn that the remains of a human ship was approaching Requium, they captured it. The Forerunners then discovered a sole human hat was aboard the ship. Concluding he was responsible for the loss of the array, they decide to kill him.
Both of these senarios seem quite possible. They also match the pattern of multi-enemies in Halo. The senarios also answer the question of the ‘ancient evil’ and ‘vengence’ 343 has described. There is, however, another possibility for those who do not believe my senerios add up. It could simply be another race that pre-dates the Forerunners and the Precursors. However you hink of it, Sentinels are almost garranteed to have a presence in Halo 4.
But enough of how I believe it should go. What do you think the true enemy is?
