mabey it could be the comfirmer cause that didnt look like the didacts symbol,but it doesnt make sense why the cryptm or whatever it is called is orange,shouldnt it be blue?plus if its the didact then mabey hes corrupted.
btw siera1117 thx for the link,it helped me out alot about halo 4 ,so bornstellar is our possible enemy.
sometimes i think its a precursor cause they want vengence,it says chief will be battling an ancient evil who wants vengence ,its possible there are still more,but its likely the didact or comfirmer.
