That's not Jim Corrigan, it's Crispus Allen, unless something happened between Revelations #6 and Final Crisis #7 that I am unaware of.
and the specter and radient were weakened during the whole of final crisis by THE PRESENCE because the war was for the freewill of humanity and THE PRESENCE wanted man to decide who won. also its very clear that the dying god mandrakk is talking about is Dax Novu, not the presence who was alive and well throughout all of final crisis and who nix uotan called GOD!
I think he is referring to Darkseid here but its been a while so I'm not sure.
