Halo 4's Story?

At the end of Halo 3, I thought to myself “So Halo’s ended? Covenant and the Flood were all wiped out?” and then I figured that Halo 4 wouldn’t have any enemies to fight. Everyone on YouTube keeps telling me that they will fight the
‘Reclaimers’, but don’t call me a n00b but… I have no idea what a ‘Reclaimer’ is. But I’ve heard on Halo Nation that after Halo 4 there will be Halo 5 and 6. So, basically what I’m asking is “What are the enemies in Halo 4?”

they haven’t revealed yet but my best but is the Precursors or Forerunners, but hey, I could be wrong.

Well a Reclaimer is a forrunner that has return to his or her farthers and mothers old halo ring and is going to reclaim and use the halo ring aganist the flood.

some people look at the concept art and think its the covanent again

John is the “last true reclaimer”, and he will be fighting an ancient evil. I’m thinking the last Precurser (which is the race that created the forerunners).
