After watching a couple of videos of the orange ball, it says that it is TheDidacts cryptum/ship like it said in the books. Plus cortana said him instead of it when she was talking about the ball since the game is halfway done, do you think we meet TheDidact somewhere after the chief crashes? So I think I summed up what the ball is and its origins, but we may not know if it is TheDidact, if Chief met TheDidact wouldn't TheDidact just gun down Chief? if he hated Reclaimers, I think that TheDidact needs chief, but the same time hates him, since the Master Builder wasn't confirmed dead, maybe TheDidact needs him to kill the master builder, I think he was last seen on instalation 004 that installation is pretty damaged and has no atmosphere at all, there is still evil things living on it, maybe the Flood? since the contanimation might of broken out? maybe the chief will visit 004 somewhere in Halo 5 or 6? maybe he activates it to kill TheDidact and the master builder and possibly a Precursor? Hope to god that wouldn't happen because heroes and legends never die.
